When performing a parallel parking maneuver, what should you do first?

The first step in performing a parallel parking maneuver is to signal your intention to park. This action is essential because it alerts other drivers and pedestrians of your plans, helping to maintain safety while you execute the maneuver. Signaling provides clear communication about your intentions, which is a critical aspect of safe driving and helps prevent accidents.

Following this initial step, it would be prudent to check your mirrors for traffic to ensure that the space is clear and safe before starting to reverse, but the act of signaling is what establishes your intent to begin the parking process. Thus, signaling is a necessary practice before taking any further actions, such as reversing into the spot or turning the steering wheel.
