Question

multiple choice: 1. when starting the engine, you should release the key or start button: a. after you check over your left shoulder. b. as you release the parking brake. c. when you hear a grinding sound. d. as soon as the engine starts.

Explanation:

When starting an engine, once it fires up and is running, you should release the key or start - button to avoid over - cranking and potential damage to the starter motor. Checking over the left shoulder is for vehicle movement, releasing the parking brake is a later step in the driving process, and hearing a grinding sound is a sign of a problem, not when to release the start mechanism.

Answer:

d. As soon as the engine starts.
