Collision Type #1:  The Right Cross

This is the most common ways to get hit (or almost get hit). A car is pulling out of a side street, parking lot, or driveway on the right. Notice that there are actually two possible kinds of 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. Even for daytime riding, a bright white light that has a flashing mode can make you more visible to motorists who might otherwise Right Cross you. Look for the new LED headlights which last ten times as long on a set of batteries as old-style lights. And helmet- or head-mounted lights are the best, because then you can look directly at the driver to make sure they see your light.

2. Honk. Get a loud horn and use it whenever you see a car approaching (or waiting) ahead of you and to the right. If you don’t have a horn, then yell “Hey!” You may feel awkward honking or yelling, but it’s better to be embarrassed than to get hit. Incidentally, many countries require bells on bicycles, but the U.S. doesn’t.

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. Ride further left. Look at the two blue lines “A” and “B” in the picture. 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. When that driver is looking down the road for traffic, he’s not looking in the bike lane or the area closest to the curb; he’s 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. Using this method has saved me on three occasions in which a motorist ran into me and I wasn’t hurt, and in which I definitely would have slammed into the driver’s side door had I not moved left.

Of course, there’s a tradeoff. Riding to the far right makes you invisible to the motorists ahead of you at intersections, but riding to the left makes you more 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 and how close they pass you, and how far you are from the next intersection. On fast roadways with few cross streets, you’ll ride farther to the right, and on slow roads with many cross streets, you’ll ride farther left.

Collision Type #2:  The Door Prize

A driver opens his 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. This kind of crash is more common than you might think, and in fact cyclists crashing into parked cars is the #1 kind of car-bike collision in Santa Barbara. We’ve compiled a list of cyclists killed by running into open car doors.

How to avoid this collision:

Ride to the left. Ride far enough to the left that you won’t run into any door that’s opened unexpectedly. You may be wary about riding so far into the lane that cars can’t pass you easily, but you’re 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.

Collision Type #3:  The Crosswalk Slam

You’re riding on the sidewalk and cross the street at a crosswalk, and a car makes a right turn, right into you. Cars aren’t expecting bikes in the crosswalk, so you have to be very careful to avoid this one. This collision is so common we’ve lost track of the number of people who’ve told us they were hit this way, such as Ray John Ray. One study showed that sidewalk-riding was twice as dangerous as road riding, and another study said it’s even more dangerous than that.

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.

Collision Type #4:  The Wrong-Way Wreck

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:

Don’t ride against traffic. Ride with traffic, in the same direction.

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

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.

How the heck are you going to make a right turn?

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 more than twice as fast! 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.

Riding the wrong way is illegal and you can get ticketed for it.

One study showed that riding the wrong way was three times as dangerous as riding the right way, and for kids, the risk is seven times greater.

Nearly one-fourth of crashes involve cyclists riding the wrong way. Some readers have challenged this, saying if 25% of crashes are from going the wrong way, then riding the right way is more dangerous because it accounts for 75% of crashes. That thinking is wrong. First off, only 8% of cyclists ride the wrong way, yet nearly 25% of them get hit — meaning wrong-way cyclists really are three times more likely to get hit than those who ride the proper way. Second, the problem with wrong-way biking is that it promotes crashes, while right-way biking does not. For example, cyclists running stop signs or red lights is 17% of their crashes.  But do we therefore conclude that not running signals causes 83% of crashes?! (Hint: No.)

Collision Type #5:  Red Light of Death

You stop to the right of a car that’s already waiting at a red light or stop sign. They can’t see you. When the light turns green, you move forward, and then they turn right, right into you. Even small 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. An Austin 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. Simply stop BEHIND a car, instead of to the right of it, as per the diagram below. This makes you very visible to traffic on all sides. It’s impossible for the car behind you to avoid seeing you when you’re right in front of it.

Another option is to stop at either point A in the diagram above (where the first driver can see you), or at 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 driver can see you clearly. 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. 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 we’re not advocating running red lights, notice it is in fact safer to 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. The moral here is not that you should break the law, but that you can easily get hurt even if you follow the law.

By the way, be very careful when passing stopped cars on the right as you approach a red light. You run the risk of getting doored by a passenger exiting the car on the right side, or hit by a car that unexpectedly decides to pull into a parking space on the right side of the street.
