Difficulty: MediumSpace Behind and Tailgaters

You are driving a commercial vehicle in moderate traffic on an interstate highway when a passenger car begins tailgating your rear bumper closely. Which of the following is the safest and most effective defensive driving action to manage this hazard?

  1. Increase the following distance between your vehicle and the vehicle ahead to allow for gradual braking.Answer
  2. B
    Flash your brake lights repeatedly to warn the driver behind to back off.
  3. C
    Increase your road speed above the posted limit to open up space behind your vehicle.
  4. D
    Make sudden lane shifts into adjacent traffic lanes to force the trailing vehicle to pass.

Answer

Increase the following distance between your vehicle and the vehicle ahead to allow for gradual braking.
When followed too closely, a commercial driver cannot control the space behind directly; therefore, the safest defensive response is to increase following distance ahead. Expanding the front cushion ensures the driver will never need to brake abruptly, allowing smooth and gradual stops that protect both vehicles and facilitate passing.

Step-by-Step Solution

1
Identify the primary danger created by a tailgating vehicle.
The tailgater eliminates the rear buffer zone, making any sudden stop by the heavy vehicle likely to cause a rear-end collision.
Commercial motor vehicles require long stopping distances, but trailing vehicles following too close cannot stop in time if the truck brakes abruptly.
2
Adjust forward vehicle spacing to compensate for the lost rear space cushion.
Opening up extra following distance in front provides ample time and distance to decelerate gently and smoothly.
Gradual deceleration prevents emergency stops and encourages the trailing driver to safely pass when an opportunity arises.

Key Concept

Defensive space management when being tailgated requires increasing forward following distance to prevent sudden stops.
