Question 1

What is the Federal Motor Vehicle Safety Standard (FMVSS) 208?

Accepted Answer

The standard governing occupant crash protection, including airbag and seatbelt requirements

Answer

FMVSS 208 establishes performance requirements for occupant protection in frontal crashes, mandating airbags, seatbelts, and their performance criteria in crash testing.

Question 2

How does Electronic Stability Control (ESC) prevent loss of vehicle control?

Accepted Answer

By automatically applying individual brakes and reducing engine power when sensors detect the vehicle is skidding

Answer

ESC uses wheel speed sensors, steering angle sensors, and yaw rate sensors to detect when a vehicle begins to lose traction, then selectively applies brakes to individual wheels to correct the vehicle's path.

Question 3

What is a crumple zone in vehicle design?

Accepted Answer

A structural area designed to deform and absorb crash energy, protecting the passenger compartment

Answer

Crumple zones are engineered to progressively deform during a collision, absorbing kinetic energy and extending the crash duration, which reduces the forces transferred to occupants in the passenger safety cell.

Question 4

What does ADAS stand for in automotive safety?

Accepted Answer

Advanced Driver Assistance Systems

Answer

ADAS encompasses technologies like adaptive cruise control, lane departure warning, automatic emergency braking, and blind-spot monitoring that assist drivers and reduce the risk of accidents.

Question 5

What is the purpose of crash test ratings from NHTSA and IIHS?

Accepted Answer

To evaluate and rate vehicle safety performance in standardized crash tests, helping consumers make informed choices

Answer

NHTSA (5-star ratings) and IIHS (Good, Acceptable, Marginal, Poor) conduct independent crash tests simulating real-world collision scenarios to assess how well vehicles protect occupants.
