Why the far hand changes the driver’s view
When a driver uses the hand farther from the door to open it, reaching across turns the upper body toward the window. The shoulders and head follow the arm, making it more likely the driver will look over a shoulder and notice a cyclist approaching from behind. This habit is often called the “Dutch reach,” though the useful part is the deliberate turn—not the name.
The danger is the door’s sudden sweep
A car door can move into a cyclist’s path with little warning. A glance in the side mirror may miss someone in a blind spot, and a cyclist can cover the remaining distance while a driver is starting to get out. Turning to reach for the handle adds a second check at the moment just before the door opens.
The method works best as a sequence: check mirrors, turn to look back, then open the door carefully. The reach encourages the turn, but it cannot guarantee that the way is clear; the driver still has to pause and look.
A small habit at the moment it matters
The technique is easy to teach because it ties a safety check to an ordinary action. Instead of relying on remembering an extra instruction, the driver’s reach itself prompts a look toward the space a door is about to enter. That extra glance can make the difference between a door opening into an empty street and into a cyclist’s path.
