Seatbelt use is a safety practice that involves wearing a strap designed to secure a person in a vehicle. It helps to prevent injuries during accidents by keeping the occupant in their seat and reducing the risk of being thrown from the vehicle. Most modern vehicles are equipped with seatbelts for all seating positions, and many countries have laws requiring their use. Wearing a seatbelt is especially important for children, who should be secured in appropriate child safety seats or booster seats based on their age and size. Studies show that seatbelt use significantly decreases the likelihood of serious injury or death in car crashes, making it a crucial aspect of road safety.
