Which measure greatly reduces the risk of injury during a car crash?

Using a seatbelt is one of the most effective measures for reducing the risk of injury during a car crash. Seatbelts are designed to secure occupants in their seats, preventing them from being thrown forward or ejected from the vehicle upon impact. This crucial function of seatbelts helps to keep passengers in a controlled position relative to the car's safety features, such as airbags, and reduces the risk of severe injuries to vital body parts during collisions.

Furthermore, seatbelts are effective in preventing injuries even in low-speed collisions, where many people might underestimate the risks involved. They are a basic yet essential safety feature that significantly contributes to the overall safety of driving, making it imperative for everyone in the vehicle to wear them at all times.

While other measures, such as airbags, helmets, and driving at lower speeds, can also enhance safety, seatbelts are consistently proven to be the primary line of defense against injuries during a crash. Airbags, for example, work in conjunction with seatbelts but are most effective when the occupant is already secured by a belt. Lower speeds certainly reduce the severity of accidents, but the use of seatbelts is a universally applicable practice that is vital regardless of speed, making it the most fundamental safety precaution
