Frequently Asked Questions
Which backing maneuver is the hardest?
Most students find alley dock (90-degree backing) the most challenging because it requires precise trailer control and spatial awareness. Practice this one the most.
How many pull-ups are allowed on the CDL backing test?
Most states allow 1-2 pull-ups (pulling forward to reposition) without penalty. Additional pull-ups result in point deductions. Encroachments (crossing boundary lines) are more serious.
Should I use my mirrors or look out the window when backing?
Use your mirrors primarily. Looking out the window is acceptable for quick checks, but examiners want to see proper mirror use. Get out and look (GOAL) if needed.
What is GOAL and when should I use it?
GOAL stands for "Get Out And Look." Use it whenever you're unsure about clearance or position. It's not penalized and shows safety awareness. Better to GOAL than hit a cone.
What happens if I hit a cone during backing?
Hitting a cone (boundary) typically results in automatic failure of that maneuver. You may be able to retry, depending on your state. Some states allow one retry; others do not.
