Traffic Occupant Protection Systems are best described as:

• A. Vehicle features that maximize comfort and luxury
• B. Vehicle features designed to reduce maintenance costs
• C. Vehicle features designed to improve engine performance
• D. Vehicle features designed to prevent crashes and protect occupants

Answer: (D)

Traffic Occupant Protection Systems are safety features in vehicles that aim to prevent crashes whenever possible and to protect people inside the vehicle if a crash occurs. This includes technologies that help avoid collisions, as well as systems that cushion and safeguard occupants during a crash, such as seat belts, airbags, reinforced passenger cabins, crumple zones, and safety electronics like electronic stability control and anti-lock brakes. That combination—preventing crashes and protecting occupants when crashes happen—is why the description focusing on preventing crashes and protecting occupants is the best fit. These features aren’t primarily about comfort or luxury, maintenance costs, or engine performance.
