A driver has parked along a city curb next to a designated bicycle lane. Which of the following describes the driver's legal responsibility before opening their street-side door?

  1. A
    Open the door immediately so approaching bicyclists recognize that someone is exiting.
  2. Check mirrors and look back for oncoming bicyclists and traffic, opening the door only when it is safe.Answer
  3. C
    Expect bicyclists in the bike lane to yield the right-of-way to parked vehicle doors.
  4. D
    Leave the street-side door open continuously while unloading cargo to alert approaching riders.

Answer

Drivers must check rear-view/side mirrors and perform a shoulder check for approaching bicyclists and traffic, opening the door only when it is completely safe to do so.
The correct answer states that drivers must check mirrors and look back for oncoming bicyclists and traffic, opening the door only when it is safe. Traffic laws strictly prohibit opening a vehicle door on the side of moving traffic unless it is reasonably safe to do so without interfering with other traffic, including cyclists.

Step-by-Step Solution

1
Identify the potential traffic hazard when parked next to a bicycle or traffic lane.
Recognize that opening a vehicle door into a travel lane can cause a collision with incoming cyclists or micro-mobility riders.
Bicycles move fast and cannot instantly stop or safely swerve around a suddenly opened door.
2
Apply standard DMV safety rules for opening vehicle doors on the street side.
Check mirrors and turn to look back before unlatching the door, opening it only when clear.
Traffic laws explicitly require drivers and passengers to ensure it is safe before opening doors facing moving traffic.
