A vehicle with __________ can stop a lot faster than one without.

Anti-lock brakes are specifically designed to prevent the wheels from locking up during hard braking, which allows the driver to maintain steering control while stopping more quickly. When a driver applies the brakes forcefully, the anti-lock braking system (ABS) automatically modulates the brake pressure to each wheel, preventing skidding. This enhanced control significantly reduces stopping distances on both dry and slippery surfaces, making it a crucial feature for improving overall vehicle safety.

In contrast, the other choices do not directly relate to the vehicle’s ability to stop faster. Passenger side airbags are a safety feature designed to protect occupants in an accident, but they do not affect stopping distance. Hard-line suspension may improve handling and ride comfort but does not influence braking efficiency. Pressure treated tires might be durable but do not contribute to a vehicle's braking capability in the same manner that anti-lock brakes do.
