If you leave your vehicle unattended, you must:

1. Turn off the engine.
2. Lock the ignition and remove the key.
3. Set the parking brake.
4. All of the above. ✓

Answer: D. All of the above.

All of the above: when you leave a vehicle unattended, you must turn off the engine, lock the ignition and remove the key, and set the parking brake.

Why this is the answer

The handbook's parking section says to set the parking brake, shift to Park or Reverse, turn off the engine, and lock the vehicle. It also says Florida law requires you to take the keys out before you leave. Because the question asks about leaving a vehicle unattended, all three listed actions belong in your routine. Choosing only one of them would leave out steps the handbook gives for parking and leaving.

Why the other answers are wrong

• A. Turn off the engine. — Turning off the engine is required, but by itself it does not cover setting the parking brake and locking the vehicle and taking the key.
• B. Lock the ignition and remove the key. — Locking the ignition and removing the key is required, but it leaves out turning off the engine and setting the parking brake.
• C. Set the parking brake. — Setting the parking brake is required, but it does not include turning off the engine or locking the vehicle and removing the key.

Remember it

A simple habit: finish your whole parking routine before you reach for the door handle.
