What should you do when preparing to leave a parallel parking spot?

Answer: B — Look over your shoulder and indicate your intention by signaling

When preparing to leave a parallel parking spot, looking over your shoulder and indicating your intention by signaling is essential for ensuring safety and effective communication with other road users. This action allows you to have a clear view of any oncoming traffic, pedestrians, or cyclists that might be in your blind spots. Signaling also alerts other drivers of your intention to merge into the lane, which can help prevent accidents and create a smoother flow of traffic. In addition, maintaining awareness of your surroundings reinforces safe driving habits, particularly in busy areas where parking is often tight and visibility can be restricted. While checking your mirrors and waiting for other cars to pass are important aspects of safe driving, relying solely on mirrors does not eliminate blind spots, and merely waiting does not address the need for signaling your intentions. Accelerating out of the parking space without first ensuring it is safe can lead to collisions. Thus, the best approach is to combine shoulder checks, signaling, and a cautious exit from the parking space.
