When parking and leaving your vehicle on a highway or street, which of the following should NOT be done?

When parking and leaving your vehicle on a highway or street, lowering the windows is not advisable. This action can pose a risk for several reasons. Firstly, it may allow for easy access to your vehicle, making it a target for theft or vandalism. Leaving windows down can also affect the security of any valuables inside, as they are more visible and accessible to passersby. Additionally, lowering the windows can lead to unwanted weather exposure (like rain or snow) inside the vehicle, or invite animals in that could cause damage when left unattended.

In contrast, turning off the engine is important for safety and to prevent emissions, locking the doors helps secure your vehicle, and checking for pedestrians is a critical step to ensure the safety of others before you exit your car. Each of these actions contributes to a safer and more responsible parking experience.
