Motorcyclists always keep safety in mind when they’re on the road. After all, when a motorcycle and a car collide, the motorcyclist has the most to lose. They have little protection against serious injuries when they’re thrown to the unforgiving ground.

Unfortunately, one thing that’s very hard for a motorcyclist to predict is a car door flung open directly in their path — and getting “doored” is a serious problem. Both the biker and the person trying to exit the vehicle can get badly hurt when this happens.

Whether you’re a passenger in a motor vehicle or a driver, the odds are high that you’re not opening your car door correctly. If you typically just use the hand nearest the door to open it, you may not be looking for ongoing bikers.

The solution to the problem is really simple: It’s called the “Dutch Reach.” To open your car door correctly (and safely), you merely need to train yourself to use the hand opposite the door to open it. In other words, people on the driver’s side of a vehicle would open their door with their right hands, while people on the passenger’s side would use their left hands. That automatically causes you to twist your body in a way that makes you look back over your shoulder so you can easily see oncoming riders.

You can save lives by reminding everyone in your vehicle to adopt this simple safety step. If you’re a motorcyclist who is just learning about the Dutch Reach, educate your friends. The more the word spreads, the more motorcycle accidents you can prevent.
