How to avoid a collision with the vehicle ahead

• Stay back. When conditions are unfavorable, increase the number of second of distance between you and the vehicle ahead.
• The Two-second / Three-second rule. Use the two-or-more second rule to establish the necessary distance between you and the vehicle ahead. When the rear bumper of the vehicle ahead of you passes a stationary marker, count "one thousand and one, one thousand and two". The moment you finish counting should be the time you reach the maker. You are too close when you pass the marker before you finish counting
• Stay alert. Watch for signal or signs of the driver's intensions
• Start stopping sooner. Delayed braking leads to panic stops, something you would not want to happen.
