We know that a following distance of two (2) seconds is effective for those traveling on dry surfaces at speeds of under 35 m.p.h.

Three (3) seconds gives a vehicle enough time for evasive steering or quick braking on dry surfaces of speeds from 35 to 45 m.p.h.

Four (4) seconds is a minimum effective following distance to steer out of a problem and quick braking on dry surfaces up to 70 m.p.h.

What if it is raining or other adverse weather is present? Add 1 to 2 seconds to your space cushion.

When should you INCREASE your following distance?

• Limited Visibility
• Tire Traction is limited
• Visual and mental Driving Tasks Increase dramatically
• Being Tailgated
• Line of sight restriction
• PATH of travel restriction
• When carrying a heavy load/pulling a trailer
• When LEARNING to drive
