What must drivers do when leaving their vehicle unattended?

When leaving a vehicle unattended, it is crucial for drivers to stop the engine, lock the ignition, and remove the keys. This practice is essential for several reasons. First, turning off the engine prevents the risk of the vehicle being accidentally set into motion or creating a fire hazard due to an unattended running engine. Locking the ignition adds another layer of security, helping to deter theft and unauthorized use of the vehicle. Furthermore, removing the keys ensures that no one can easily start the vehicle while it is unattended.

Leaving the engine running could lead to various safety and security issues, such as the risk of theft or accidents. Similarly, leaving windows open can jeopardize the vehicle's security by allowing access to valuables inside. Keeping the engine running but closing the windows does not address the fundamental safety concern of leaving a vehicle unattended. Thus, the recommended practice for responsible vehicle operation is to stop the engine, secure the ignition, and take the keys when leaving the vehicle.
