Final answer:
The first step in parallel parking is turning on your signal to let other drivers know what you are going to do.
Step-by-step explanation:
The first step in parallel parking is B) Turn on signal to communicate your intentions to vehicles behind you. This is an important safety measure to indicate to other drivers that you are about to perform a parking maneuver. The next steps would involve positioning your vehicle next to the one you plan to park behind, and then proceeding with the actual parking process which includes steering and adjusting the car's position within the parking space.
The first step when parallel parking is to position the vehicle 2 to 3 feet and parallel to the vehicle you plan to park behind. This ensures that you are aligned with the parking space and have enough room to maneuver. Turning on your signal (option B) comes next to communicate your intentions to vehicles behind you. After that, you should slowly back the vehicle, steering sharp and quickly right to begin the parking maneuver.
