If you are parked parallel to the curb, you may get out of the car on the traffic side only:

  1. During the daytime when other drivers can see you.
  2. When the traffic light at the closest intersection turns red.
  3. When you won't interfere with oncoming vehicles. ✓
  4. If you use your four-way flashers first.

Answer: C. When you won't interfere with oncoming vehicles.

You may get out on the traffic side only when doing so won't interfere with oncoming vehicles.

Why this is the answer

The manual's parallel-parking section says that after you park, you must not open the door on the roadside when it would interfere with bicyclists and other traffic. The review question in the same chapter asks whether you may open a roadside door when there is no oncoming traffic. That points to the same condition: before opening into the traffic side, make sure your door will not get in the way of vehicles or other road users. The other choices add conditions like daylight, a red light, or flashers that the manual does not give as permission.

Why the other answers are wrong

Remember it

Before you swing a door into the traffic side, ask whether anyone coming would have to change course.
