Opening a car door is something most of us do automatically, without a second thought. Yet many serious accidents happen not on the road, but in the split second when someone exits a vehicle. Safety experts now urge drivers and passengers to adopt a simple habit known as the “far-hand reach” — a tiny change that dramatically reduces these risks.The technique is straightforward: use the hand farthest from the door to open it. In the U.S., that means a driver uses their right hand to open the door on the left side. It may seem insignificant, but the motion forces your body to rotate, prompting you to check your mirror and glance over your shoulder.

That natural turn is crucial. In that quick moment, you’re far more likely to spot a cyclist, pedestrian, or oncoming car before the door swings open.Organizations such as the National Safety Council promote this habit because it prevents “dooring” — when a car door suddenly opens into the path of a passing cyclist or vehicle. These incidents cause thousands of injuries every year and are almost entirely preventable.The far-hand reach requires no tools, no technology, and no cost. It’s a simple act of mindfulness that, with repetition, becomes automatic. Teaching yourself to pause, turn, and look transforms an ordinary movement into a built-in safety check.
