Which of the following factors has direct influence on the stopping distance of the passenger car?
Description
In calculations of a vehicle's stopping distance, the element of mass is not a factor.
Explanation
Correct answer: The driver's reaction time.
Stopping distance is the sum of reaction distance and braking distance. It is directly influenced by factors such as: vehicle speed, driver's reaction time, the condition of the road surface (e.g., dry, wet, icy), and the technical condition of the vehicle (tyres, brakes). The higher the speed and the poorer the conditions, the longer the stopping distance.
