Explanation
When vehicles ahead do something unexpectedly, you will need time to react. Always leave enough room between your vehicle and the vehicle ahead so you can stop safely if the other vehicle stops suddenly. Maintaining a following time of 4 seconds improves your line of sight, and allows more time to avoid hazards.
