Do cars with ABS stop more quickly than cars without?

Perhaps, but that’s not the main purpose of ABS. It is a system designed to help you maintain control of the vehicle during emergency braking situations, not necessarily make the car stop more quickly. ABS may shorten stopping distances on wet or slippery roads and most systems may shorten stopping distances on dry roads. On very soft surfaces, such as gravel or unpacked snow, ABS may actually lengthen stopping distances. In wet or icy conditions, you should still make sure you drive carefully, always keep a safe distance behind the vehicle in front of you, and maintain a speed consistent with the road conditions.
