ELDT Backing and Docking 2

Question 1

What is 'jackknifing' during a backing maneuver?

Accepted Answer

When the trailer swings past 90 degrees to the tractor and folds

Answer

Jackknifing occurs when the angle between the tractor and trailer exceeds a safe limit (past 90 degrees), causing the trailer to fold sharply against the tractor.

Question 2

Before backing into a dock, what should a driver inspect on foot?

Accepted Answer

The dock height, overhead clearances, the ground for obstacles, and the pathway

Answer

A pre-backing walk-around should check dock height, overhead obstacles, the ground for debris or people, and ensure the pathway is clear.

Question 3

What should a driver do if the trailer begins to drift off target during a blind-side backing maneuver?

Accepted Answer

Pull forward to reposition and start again if needed

Answer

Pulling forward to reposition gives the driver a fresh angle and better control rather than attempting to correct a large error while still moving backward.

Question 4

What is the proper use of hazard lights when backing to a dock in a busy yard?

Accepted Answer

Activate hazard lights to warn nearby pedestrians and vehicles of the backing movement

Answer

Activating hazard lights alerts other yard workers and drivers that the truck is actively backing, improving overall safety in busy dock areas.

Question 5

How should a driver handle a dock approach when dock bumpers are damaged or missing?

Accepted Answer

Report the condition and back with extra care to avoid striking the dock

Answer

Missing or damaged bumpers increase the risk of dock damage and injury; the driver should report it and proceed with extra caution to protect equipment and personnel.
