On what factors does the safety distance to be kept from the vehicle ahead fundamentally depend?

Question

DentroTest · Accepted Answer

According to the General Traffic Regulations, every driver traveling behind another vehicle must keep a sufficient separation to be able to stop, in the event of sudden braking, without colliding with it. This safety distance is not fixed; it depends directly on speed (the higher the speed, the greater the braking distance), on the condition of the brakes and tires (grip) and on the condition of the roadway as affected by weather or environmental factors (rain, ice, snow or fog). The options pointing to traffic density or the type of preceding vehicle are incorrect, since the distance required to stop one's own vehicle safely depends on the laws of physics and on the condition of the road and of one's own vehicle.
