What should you check for before entering a vehicle?

Checking for children, pets, and traffic before entering a vehicle is crucial for ensuring safety. This action helps prevent accidents by making sure there are no obstacles or hazards nearby that could lead to injury. For example, small children or pets may be under or near the vehicle, and failing to notice them can result in serious accidents when starting to move the car. Additionally, being aware of surrounding traffic is essential to avoid conflict with other vehicles or cyclists that may be passing by.

The other options, while they are important aspects of vehicle safety, pertain to different aspects of vehicle readiness or maintenance rather than immediate safety concerns before entering. Adjusting seats and mirrors is important for a comfortable driving position but does not directly address immediate dangers around the vehicle. Checking tire pressure and engine fluid levels is crucial for vehicle maintenance but can be done at a different time when preparing for a journey, rather than being a step taken immediately before entering the vehicle.
