What is a fundamental safety precaution before driving?

A fundamental safety precaution before driving is fastening the seatbelt. Wearing a seatbelt is one of the simplest yet most effective ways to protect yourself in the event of a collision. It helps to keep the driver and passengers securely in their seats, reducing the risk of injury by preventing ejection from the vehicle and minimizing movement during a crash.

While checking tire pressure, adjusting the rearview mirror, and turning on headlights are also important safety measures, they focus on vehicle readiness and visibility rather than personal protection. Fastening the seatbelt directly impacts the safety of the occupants within the vehicle, making it a critical step before beginning to drive.
