How should you behave to drive at a safe speed?
Show the correct answer
Correct answer
A. Maintain the speed to avoid collision with the preceding vehicle.
Explanation
The question is about driving at a safe speed. You should keep a speed that makes it possible to avoid running into the vehicle in front - answer A.
The Road Traffic Act requires you to drive at a speed that ensures control over the vehicle, taking into account the traffic conditions, and to keep the distance needed to avoid a collision when the vehicle in front brakes. So a safe speed is one at which you have time to stop. Following only the signs (answer B) or only the general limit in a built-up area (answer C) is not enough - the limit is the upper boundary, and on wet rails, in fog or in heavy traffic, a safe speed is often much lower.
