Show the correct answer
Correct answer
A. Adaptive cruise control (active).
Explanation
The question is about a driver assistance device that makes it easier to keep a following distance from the vehicle in front. It is adaptive cruise control, also called active cruise control - answer A.
The Road Traffic Act requires you to keep the distance needed to avoid a collision if the vehicle in front brakes, and on a motorway or an expressway - at least half of the speed in metres. Adaptive cruise control uses a radar or a camera to measure the distance to the vehicle in front of you and slows down by itself when you get closer to it, and then speeds up to the set speed. The lane keeping assistant (answer B) makes sure that you do not drift out of your lane, but it does not control the distance. Electronic stability control (answer C) counteracts skids. Remember that each of these systems only helps - you are still responsible for the distance.
