What is a primary safety feature of newer vehicles regarding braking?

Answer: B — Anti-lock braking systems

The primary safety feature of newer vehicles regarding braking is the anti-lock braking system (ABS). ABS is designed to prevent the wheels from locking up during heavy braking or when braking on slippery surfaces. This technology helps maintain steering control during a skid, allowing the driver to maneuver away from potential hazards while braking. This enhanced control significantly reduces the risk of accidents in emergency situations, making it a crucial element in vehicle safety. While increased horsepower, airbag deployment, and automatic steering correction contribute to the overall safety and performance of a vehicle, they do not specifically address braking performance in the same way that ABS does. Increased horsepower relates to engine performance rather than braking capability, airbags primarily protect occupants during a collision rather than prevent one, and automatic steering correction is more about maintaining lane position than directly enhancing braking effectiveness. Therefore, the anti-lock braking system stands out as the primary safety feature specifically designed to improve braking safety in newer vehicles.
