What is the law regarding seat belts in Illinois?

In Illinois, the law mandates that all passengers in a vehicle must be secured by seat belts, irrespective of their age or where they are seated within the vehicle. This comprehensive requirement aims to enhance safety for everyone in the vehicle and reduce the risk of injury in the event of a crash. The law applies not only to the driver and front-seat passengers, but also extends to those in the back seat, ensuring that all occupants are protected.

The rationale behind this regulation is rooted in the understanding that unrestrained passengers can become dangerous projectiles during an accident and that wearing a seat belt significantly increases the likelihood of surviving a crash or reducing the severity of injuries. Therefore, the correct answer reinforces the importance of universal seat belt use across all positions in the vehicle.
