Which of the following elements operate automatically in the event of an accident?
Active and passive safety
Explanation
**Seat belts** are a component of **passive safety** in vehicles. This means they are designed to **protect passengers** in the event of an accident, reducing the risk of injury. They operate **automatically**, meaning they do not require any action from the driver or passengers to activate during an accident.
On the other hand, **brakes** and **lighting** are part of **active safety**. These elements are designed to **prevent accidents** and require the driver to use them actively. For example, the driver must press the pedal to activate the brakes and manually turn on the lights.
In summary, seat belts act automatically in the event of an accident, while brakes and lighting require driver intervention to function.
