Question 7089
What is the main cause of rear-end collisions?
- Driving at an abnormally low speed.
- Not keeping a safe following distance from the vehicle ahead.
- Driving at a speed over 100 km/h.
Show answer and explanation
Correct answer: Not keeping a safe following distance from the vehicle ahead.
A rear-end collision happens when the vehicle ahead brakes and the driver behind does not have enough space to stop in time. That is why the main cause is failing to keep a safe following distance. In the image, the blue car is following closely behind the gray car, whose brake lights are on. Following too closely is dangerous at any speed.
