Difficulty: EasyBicycles and Micro-Mobility Devices

After parallel parking along a city street adjacent to a bicycle lane, a driver is preparing to exit the vehicle. Which action should the driver take to prevent a collision with an approaching bicyclist or micro-mobility user?

  1. Check side mirrors and perform a shoulder check to scan for approaching riders before opening the doorAnswer
  2. B
    Open the door quickly so approaching riders have maximum time to spot the opened door
  3. C
    Rely exclusively on the interior rearview mirror to check for riders behind the vehicle
  4. D
    Sound the horn twice to alert any nearby bicyclists that the car door is opening

Answer

Check side mirrors and perform a shoulder check to scan for approaching riders before opening the door.
Before opening a vehicle door into traffic or a bike lane, drivers must visually check side mirrors and look over their shoulder into blind spots. Using a proper shoulder check (or the Dutch Reach technique) prevents 'dooring' collisions with oncoming cyclists or scooter riders.

Step-by-Step Solution

1
Identify the primary hazard when exiting a parked vehicle near bicycle traffic.
Opening a driver-side door into an active bike lane or street can cause a 'dooring' accident with a bicyclist or micro-mobility operator.
Vulnerable road users travel quietly and closely along parked vehicles.
2
Determine the proper visual scanning technique prior to opening the vehicle door.
A driver must look into side mirrors and physically turn their head over the left shoulder to verify the blind spot is clear.
Mirrors alone do not eliminate side blind spots where cyclists ride.
