Driver's License Test Prep
California Practice Sharing the Road

Before opening your door on the traffic side of a parked vehicle, the manual tells you to check for what?

  1. A.
    Pedestrians on the sidewalk behind you
  2. B.
    Oncoming buses in the next lane
  3. C.
    Approaching motorcyclists Correct
The Why

The answer is "Approaching motorcyclists"

The manual tells drivers to check for motorcyclists before opening a door next to traffic, because motorcycles are small, easy to miss in a mirror, and a door pushed open into their path can knock a rider down. The pedestrian answer comes from readers who generalize the rule to any bystander, when the manual anchors it to a door opening into a traffic lane where a motorcycle is the specific hazard.

Why the others miss

The traps in the wrong answers

A. Pedestrians on the sidewalk behind you

The manual's warning is about the traffic side of the vehicle, not the sidewalk behind you. This answer carries over the parking-lot habit of checking for people walking past a car, rather than the traffic-side motorcyclist the manual singles out.

B. Oncoming buses in the next lane

The manual names motorcycles as the traffic-side hazard here, not larger vehicles that already fill a mirror. This answer reaches for the biggest traffic-side vehicle a driver worries about, when the manual singles out the small rider that disappears in mirrors.
