Explain the role of seat belts in preventing injuries during a collision.✔✔Seat belts help to restrain occupants, preventing them from being thrown from the vehicle or striking the interior during a collision.
Describe how airbags contribute to vehicle occupant safety.✔✔Airbags inflate rapidly upon impact, cushioning the occupants and reducing the risk of severe injuries by preventing them from colliding with hard surfaces.
What is the purpose of electronic stability control (ESC) in modern vehicles?✔✔ESC helps prevent skidding and loss of control by automatically applying brakes to individual wheels when it detects a loss of traction.
Explain the function of Anti-lock Braking System (ABS) in preventing accidents.✔✔ABS prevents the wheels from locking during hard braking, allowing the driver to maintain steering control while stopping the vehicle.

Describe how traction control systems (TCS) work in vehicles.✔✔TCS helps prevent wheel spin during acceleration by reducing engine power or applying brakes to wheels that are slipping.
Explain why child safety seats are critical in reducing injury risk for young passengers.✔✔Child safety seats are designed to securely restrain children in the event of a crash, offering the appropriate size and protection based on their age, weight, and height.
What is the purpose of the crumple zone in a vehicle?✔✔Crumple zones are designed to absorb and dissipate the energy from a collision, reducing the force transferred to the occupants and minimizing injury.
Explain the importance of tire pressure monitoring systems (TPMS) in vehicle safety.✔✔TPMS alerts drivers when tire pressure is too low, reducing the risk of tire blowouts and improving vehicle handling and fuel efficiency.
Describe how lane departure warning (LDW) systems assist drivers.✔✔LDW systems alert drivers when the vehicle unintentionally drifts out of its lane, helping to reduce the risk of accidents due to inattention or fatigue. 2 / 3

Explain how forward collision warning (FCW) systems work to prevent accidents.✔✔FCW uses sensors to detect potential collisions with vehicles or objects ahead, providing a warning to the driver to take corrective action.
Describe the role of automatic emergency braking (AEB) in reducing rear-end collisions.✔✔AEB detects an impending collision and automatically applies the brakes if the driver does not respond in time, helping to prevent or mitigate the severity of rear-end accidents.
What is the benefit of adaptive cruise control in improving road safety?✔✔Adaptive cruise control maintains a safe distance from the vehicle ahead by adjusting the speed, reducing the likelihood of rear-end collisions.
Explain the importance of pedestrian detection systems in modern vehicles.✔✔Pedestrian detection systems use sensors to identify pedestrians in the vehicle’s path and can trigger an alert or apply the brakes to avoid a collision.
Describe how blind spot monitoring systems (BSM) enhance driver awareness.
