As we bicycle around town, I avoid getting hit by cars all the time, by taking very specific preventative measures which definitely keep me from getting killed. 

What this page aims to show you is real ways you can get hit and real ways to avoid them. This is a far cry from normal bike safety publications which tell you things of questionable usefulness, such as admonishing you to always signal your turns. (It's actually more important to ride in such a way that it's not NECESSARY for cars to know where you're going -- if a car has to know what you're about to do in order to avoid hitting you, then you're a prime candidate for getting hit. Even if you signal.) Many bike safety texts also think they're being helpful by telling you to not ride with two people on one bike. (How many people actually do this anyway? Why aren't they using that space to address things which you're much more likely to actually experience?) Most bike safety manuals also emphasize helmets with a certain zeal, as though simply wearing a helmet magically makes you safe. Well, consider this for a moment: Wearing a helmet will do absolutely nothing to prevent you from getting hit by a car! Sure, helmets might help you if you get hit, and I wear one myself, but your #1 goal should be to avoid getting hit in the first place! Plenty of cyclists are killed by cars even though they were wearing helmets! Ironically, if they had ridden WITHOUT helmets, yet followed the guidelines listed below, they might still be alive today. Don't confuse wearing a helmet with biking safely.

This is the most common type of collision or potential collision. A car is pulling out of a side street, parking lot, or driveway on the right. Notice that this are actually two different kinds of possible collisions here: Either you're in front of the car and the car hits you, or the car pulls out in front of you and you slam into it.

How to avoid this collision:

1. Get a headlight. If you're riding at night, you should absolutely use a front headlight. It's required by law, anyway.

2. Honk. Get a bell or a horn and USE IT whenever you see a car approaching (or waiting) ahead of you and to the right. You may feel awkward ringing your bell or honking your horn, but it's better to be embarrassed than to get hit. Do it.

3. Slow down. If you can't make eye contact with the driver (especially at night), slow down so much that you're able to completely stop if you have to. Sure, it's inconvenient, but it beats getting hit. Doing this has saved my life on too many occasions to count.

4. Move left. Notice the two blue lines "A" and "B" in the diagram. You're probably used to riding in "A", very close to the curb, because you're worried about being hit from behind. But take a look at the car in the diagram. When that motorist is looking down the road for traffic, they're not looking in the bike lane or the area closest to the curb; they're looking in the MIDDLE of the lane, for other cars. The farther left you are (such as in "B"), the more likely the driver will see you. There's an added bonus here: if the motorist doesn't see you and starts pulling out, you may be able to go even FARTHER left, or may be able to speed up and get out of the way before impact, or roll onto their hood as they slam on their brakes. In short, it gives you some options. Because if you stay all the way to the right and they pull out, your only "option" may be to run right into the driver's side door. 

Of course, there's a tradeoff. Riding to the far right makes you invisible to the cars ahead of you at intersections, but riding to the left makes you vulnerable to the cars behind you. Your actual lane position may vary depending on how wide the street is, how many cars there are, how fast & how close they pass you, and how far you are from the next intersection.

A parked car opens its door right in front of you. You run right into it if you can't stop in time. If you're lucky, the motorist will exit the car before you hit the door, so you'll at least have the pleasure of smashing them too when you crash, and their soft flesh will cushion your impact.

How to avoid this collision:

Ride to the left. Ride far enough to the left that even if someone swings their door out all the way, it won't hit you. You may be wary about riding so far into the lane that cars can't pass you easily, but you're MUCH more likely to get doored by a parked car if you ride too close to it than you are to get hit from behind by a car which can clearly see you.

You stop at a red light (or stop sign) immediately to the right of an automobile that's waiting at the same light. They can't see you. When the light turns green, you move forward, and then they turn right, right into you. Simple cars can do you in this way, but this scenario is especially dangerous when it's a bus or a semi that you're stopping next to. A cyclist was killed in 1994 when he stopped to the right of a semi, and then it turned right. He was crushed under its wheels.

How to avoid this collision:

Don't stop in the blind spot. Look at the diagram. Either stop in point A, where the driver can see you, or stop in point B, behind the first car so it can't turn into you, and far enough ahead of the second car so that the second car can see you clearly. And it does no good to avoid stopping to the right of the first car if you're going to make the mistake of stopping to the right of the second car. EITHER car can do you in.

If you chose spot A, then ride quickly to cross the street as soon as the light turns green. Don't look at the motorist to see if they want to go ahead and turn. First of all, if you're in spot A and they want to turn, then you're in their way. Why did you take spot A if you weren't eager to cross the street when you could? When the light turns green, just go, and go quickly. (But make sure cars aren't running the red light on the cross street, of course.)

If you chose spot B, then when the light turns green, DON'T pass the car in front of you -- stay behind it, because it might turn right at any second. If it doesn't make a right turn right away, it may turn right into a driveway or parking lot unexpectedly at any point. Don't count on drivers to signal! They don't. Assume that a car can turn right at any time. (NEVER pass a car on the right!) But try to stay ahead of the car behind you until you're through the intersection, because otherwise they might try to cut you off as they turn right.

While I'm not advocating running red lights, notice it is in fact safer to break the law and run the red light if there's no cross traffic, than it is to wait legally at the red light directly to the right of a car, only to have it make a right turn right into you when the light turns green.

A car passes you and then tries to make a right turn right in front of you, or right into you. Just because you're on a bicycle they think you're not going very fast (even if you are) so it never occurs to them that they can't pass you in time. Even more frustrating is that even if you have to slam on your brakes to avoid hitting them, they often won't feel they've done anything wrong. This kind of collision is very hard to avoid because you typically don't see it until the last second, and because there's nowhere for you to go when it happens.

How to avoid this collision:

1. Ride to the left. Taking up the whole lane makes it harder for cars to pass you to cut you off or turn into you. Don't feel bad about taking the lane: if cars didn't threaten your life by turning in front of or into you or passing you too closely, then you wouldn't have to. Unfortunately, this is a trade-off: it's often safer, or at least more comfortable, to ride far to the right. Your choice of riding position will probably depend on the particular roadway you're on. If the lane you're in isn't wide enough for cars to pass you safely, then you should be taking the whole lane anyway.

2. Glance in your mirror before approaching an intersection. (If you don't have a mirror, get one now.) Be sure to look in your mirror well before you get to the intersection. When you're actually going through an intersection, you'll need to be paying very close attention to what's in front of you.

You're passing a slow-moving car (or even another bike) on the right, when it unexpectedly makes a right turn right into you, trying to get to a parking lot,driveway or side street.

How to avoid this collision:

1. Don't pass on the right. This collision is very easy to avoid. Just don't pass any vehicle on the right. If a car ahead of you is going only 10 mph, then you slow down, too, behind it. It will eventually start moving faster. If it doesn't, pass on the left when it's safe to do so.

When passing cyclists on the left, announce "on your left" before you start passing, so they don't suddenly move left into you. (Of course, they're much less likely to suddenly move left without looking, where they could be hit by traffic, then to suddenly move right, into a destination.) If they're riding too far to the left for you to pass safely on the left, then announce "on your right" before passing on the right.

If a bunch of cars are stopped at a light, then you can try passing on the right cautiously, being prepared in case the traffic starts moving again unexpectedly.

Note that when you're tailing a slow-moving vehicle, ride behind it, not in its blind spot immediately to the right of it. Even if you're not passing a car on the right, you could still run into it if it turns right if you're on the right side of it. Give yourself enough room to brake if it turns.

2. Look behind you before turning right. Here's your opportunity to avoid hitting cyclists who violate tip #1 above and try to pass you on the right. Look behind you before making a right-hand turn to make sure a bike isn't trying to pass you. (Also remember that they could be coming up from behind you on the sidewalk while you're on the street.) Even if it's the other cyclist's fault for trying to pass you on the right when you make a right turn and have them slam into you, it won't hurt any less.

A car approaching from ahead tries to make a left turn right into you. This is similar to #1, above. 

How to avoid this collision:

1. Get a headlight. If you're riding at night, you should absolutely use a front headlight. It's required by law, anyway.

2. Slow down. If you can't make eye contact with the driver (especially at night), slow down so much that you're able to completely stop if you have to. Sure, it's inconvenient, but it beats getting hit.

You innocently move a little to the left to go around a parked car or some other obstruction in the road, and you get nailed by a car coming up from behind.

How to avoid this collision:

1. Never, ever move left without checking your mirror or looking behind you first. Some motorists like to pass cyclists within mere inches, so moving even a tiny bit to the left unexpectedly could put you in the path of a car.

2. Use a handlebar mirror. If you don't have one, go to a bike shop and get one.

This is what many cyclists fear the most, but it's not the most common kind of accident (except maybe at night, or on long-distance rides outside the city). However, it's one of the hardest collisions to avoid, since you're not usually looking behind you. 

How to avoid this collision:

1. Get a rear light. If you're riding at night, you absolutely should use a flashing red rear light.

Bike shops have red rear blinkies for $15 or less.  We can't stress this item enough: If you ride at night, get a rear light!

2. Choose wide streets. Ride on streets whose outside lane is so wide that it can easily fit a car and a bike side by side. That way a car may zoom by you and avoid hitting you, even if they didn't see you!

3. Choose slow streets. The slower a car is going, the more time it has to see you. Navigate the city by going through neighborhoods. Learn how to do this.

4. Use back streets on weekends. The risk of riding on Friday or Saturday night is MUCH greater than riding on other nights because all the drunks are out driving around. I avoid riding on Friday & Saturday nights as much as possible.

5. Get a mirror. Get a mirror and use it. If it looks like a car doesn't see you, hop off your bike and onto the sidewalk. Mirrors cost $5-15. Trust me, once you've ridden a mirror for a while, you'll wonder how you got along without it. 

A car makes a right turn, right into you, as you're biking through the crosswalk between two sidewalks. Cars aren't expecting bikes in the crosswalk, so you have to be VERY careful to avoid this one. 

How to avoid this collision:

1. Get a headlight. If you're riding at night, you should absolutely use a front headlight. It's required by law, anyway.

2. Slow down. Slow down enough that you're able to completely stop if necessary.

3. Don't ride on the sidewalk in the first place. Crossing between sidewalks can be a fairly dangerous maneuver. If you do it on the left-hand side of the street, you risk getting slammed as per the diagram. If you do it on the right-hand side of the street, you risk getting slammed by a car behind you that's turning right. You also risk getting hit by cars pulling out of parking lots or driveways. These kinds of accidents are hard to avoid, which is a compelling reason to not ride on the sidewalk in the first place.

And another reason not to ride on the sidewalk is that you're threatening to pedestrians. Your bike is as threatening to a pedestrian as a car is threatening to you. Finally, riding on the sidewalk is illegal in some places. (In Austin, those places are the Drag, and downtown on 6th St. and on Congress). If you do plan on riding on sidewalks, do it slowly and EXTRA carefully, ESPECIALLY when crossing the street between two sidewalks.

You're riding the wrong way (against traffic, on the left-hand side of the street). A car makes a right turn from a side street, driveway, or parking lot, right into you. They didn't see you because they were looking for traffic only on their left, not on their right. They had no reason to expect that someone would be coming at them from the wrong direction.

Even worse, you could be hit by a car on the same road coming at you from straight ahead of you. They had less time to see you and take evasive action because they're approaching you faster than normal (because you're going towards them rather than away from them). And if they hit you, it's going to be much more forceful impact, for the same reason. (Both your and their velocities are combined.)

How to avoid this collision:

Ride in the same direction as traffic. That is, do NOT ride on the left-hand side of the road which would make you face oncoming traffic.

Riding against traffic may sound like a good idea because you can see the cars that are passing you, but it's not. Here's why:

1. Cars which pull out of driveways, parking lots, and cross streets (ahead of you and to the left), which are making a right onto your street, aren't expecting traffic to be coming at them from the wrong way. They won't see you, and they'll plow right into you.
2. How the heck are you going to make a right turn?
3. Cars will approach you at a much higher relative speed. If you're going 15mph, then a car passing you from behind doing 35 approaches you at a speed of only 20 (35-15). But if you're on the wrong side of the road, then the car approaches you at 50 (35+15), which is 250% faster! Since they're approaching you faster, both you and the driver have lots less time to react. And if a collision does occur, it's going to be ten times worse.
4. Riding the wrong way is illegal and you can get ticketed for it. Bruce Mackey says that 25% of cycling collisions are the result of the cyclist riding the wrong way.

There's one possible exception to riding the wrong way. When you're riding in the country on narrow roads, it may be helpful to ride against traffic so you can see what you're up against. Compared to city traffic, country traffic is likely to have less roadspace for bikes and cars to share. That being the case, riding the wrong way allows you to bail into the shoulder if a car doesn't see you. You don't have problem #1 above because side traffic is rare, and #2 is avoided because you're riding primarily along one road and not turning right.

Country traffic is more likely to be sparse, which means that you may have the ability to switch to the "correct" side of the road when a car approaches you from ahead. 

Avoid busy streets.

One of the biggest mistakes that people make when they start biking is to take the exact same routes they used when they were driving. It's usually better to take the streets with fewer and slower cars. Sure, cyclists have a right to the road, but that's a small consolation when you're dead. Consider how far you can take this strategy: If you learn your routes well, you'll find that in many cities you can travel through neighborhoods to get to most places, only crossing the busiest streets rather than traveling on them. 

Light up.

Too obvious? Well, if it's so obvious, then why do most night-time cyclists ride without lights? Bike shops have rear red blinkies for $15 or less. Headlights aren't quite so easy, because most bike headlights have sorry battery life (usually only a few hours of run time). One solution is the $30 LightWave flashlight, which runs for 15 hours on rechargeable AA batteries (even longer on alkalines). The secret to the long battery life is that the light comes from four white LED's, which lightly sip battery juice compared to standard incandescent lights. You'll need to rig up a way to mount the flashlight to your handlebars, because it's not designed with bikes in mind.

Ride as if you were invisible.

Assume that motorists don't know you're there and ride in such a way that they won't hit you even if they don't see you. You're not trying to BE invisible, you're trying to make it irrelevant whether cars see you or not. If you ride in such a way that a car has to see you to take action to avoid hitting you (e.g., by their slowing down or changing lanes), then that means they will definitely hit you if they don't see you! But if you stay out of their way, then you won't get hit even if they didn't notice you were there.

On very fast roads, cars will have less time to see you because they're approaching you so fast. Now, you should avoid fast roads in the first place if at all possible, unless there's plenty of room for a car and a bike side by side. And if there IS such room, then on fast roadways, you can practice invisibility by riding to the extreme right. If you're far enough right that you're not in the part of the lane the cars are in, then they'll zoom by and won't hit you, even if they never saw you. (exceptions to riding on the extreme right are noted below)

Here's another example: It's a good idea to signal a left turn, but it's a better idea to make your left turn at a time or place where there aren't cars behind you that could hit you while you're stopped and waiting to make that turn. You can hang out in the middle of the street, stopped, with your left arm out, waiting to make your turn, but you're counting on cars behind you to see you and stop. If they don't see you, you're in trouble.

Naturally we don't advocate running red lights, but if you're the kind of person who does, then apply the invisibility principle when deciding on whether to run a particular light: Could any cross traffic possibly hit me if I were invisible? If yes, then absolutely don't do it. Never make a car have to slow down to avoid hitting you. Remember, the more you rely on cars to see you to avoid hitting you, the more chances they'll have to actually do so.

Remember, you're not trying to BE invisible, you're just riding with the assumption that cars can't see you. Of course, you certainly WANT them to see you, and you should help them with that. That's why you'll wave to motorists whom you think might be about to pull out in front of you, and why you'll be lit up like a Christmas tree at night (front and rear lights).

There are exceptions to riding as though you were invisible. For example, often you'll need to command a whole lane of traffic instead of riding to the extreme right, for the reasons mentioned in the next section.

Take the whole lane when appropriate.

While you'll often prefer to ride to the extreme right to keep out of the way of cars passing you, it's often safest to take the whole lane, or at least move a little bit to the left. As you'll see from diagram #1 below, riding a bit to the left allows cars at cross streets at intersections to see you better. Also, you should take the lane if cars are passing you too closely from behind. This requires cars behind you to see you and either slow down or change lanes. Then again, if you're on the kind of street where you've got cars blocked up behind you or constantly changing lanes to get around you, you're probably on the wrong street and should find a quieter neighborhood street.

By the way, it's perfectly legal for you to take the lane. Texas State Law (and the laws of most other states) says you have to ride as far to the right as is "practicable". Here are some things that make it impracticable to ride to the extreme right:

1. Cars are passing you too closely. If the lane is too narrow for cars to pass you safely, then move left and take the whole lane. Getting buzzed by cars is dangerous.
2. Cars are parked on the right-hand side of the road. If you ride too close to these you're gonna get doored when someone gets out of their car. Move left.
3. You're in a heavy traffic area with lots of side streets, parking lots, or driveways ahead and to your right. Cars turning left won't see you because they're looking for traffic in the MIDDLE of the road, not on the extreme edge of the road. Move left. See Collision #1 diagram below.

If you're paying attention, you'll notice that there are risks to both riding to the extreme right as well as taking the lane. If you wanted a steadfast rule, then sorry, it isn't that simple. (But take heart, because many of the OTHER concepts we mention in our Top 10 list above work 100% of the time.) If you ride all the way to the right, you risk getting doored, and you make it hard for cars at cross streets at intersections to see you. But if you take the lane, you'll definitely get hit if a car behind you doesn't see you. To make it more likely that they'll see you when you're taking the lane, be lit up like a Christmas tree at night, and take neighborhood streets when you can, since the cars will be traveling slower and therefore approach you from behind slower, and have more time to see you.
