What must a driver do before switching into reverse while parallel parking?

Before switching into reverse while parallel parking, a driver must check for pedestrians and oncoming traffic. This is crucial because reversing a vehicle can create blind spots, making it difficult for the driver to see other road users. By ensuring the area is clear, the driver helps prevent potential accidents or near misses with pedestrians, cyclists, or other vehicles.

Turning on hazard lights can be helpful when temporarily stopping the vehicle but is not a requirement specifically before reversing. Signaling left may not always be relevant since the driver may not be turning onto a different lane or road. Honking the horn is not a standard procedure for reversing and could startle pedestrians or other road users, potentially leading to unsafe situations. Thus, checking for safety first helps ensure a smooth and safe maneuver.
