Opening a car door is something most people do without thinking, yet a simple change in how you do it can prevent serious accidents. Safety experts recommend using your right hand to open the door — a technique known as the “far-hand reach.” For drivers in the U.S., this means using the hand farthest from the door. It may seem like a small adjustment, but it encourages you to naturally turn your body and check your mirrors and blind spot before stepping out.

By reaching across your body, you’re prompted to glance over your shoulder, helping you spot oncoming cyclists, pedestrians, or passing vehicles. This extra movement reduces the risk of “dooring” accidents — situations where a car door suddenly opens into the path of a cyclist or another motorist. Organizations like the National Safety Council endorse this method as an easy, cost-free way to improve safety for everyone on the road.

The far-hand reach works in busy city streets, parking lots, or anywhere traffic and visibility make exits unpredictable. It’s a practical, low-effort habit that can quickly become second nature. Each time you exit your car, use your right hand to open the door, turn your head, check for movement, and open slowly.

Though it’s a small gesture, its impact is significant. This one habit gives you a crucial moment of awareness that can prevent injury and even save lives. Opening your car door with your right hand isn’t just a driving tip — it’s a reminder that mindfulness in simple actions can make every journey safer for everyone.
