Space Management System Cont'd
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
