Top 10 Failure Reasons (Ranked by Frequency)

#1

Pre-Trip Inspection Failures

25% of failures

Problem: Forgetting components, wrong order, or unable to explain function.

Fix: Practice the ENTIRE pre-trip from memory daily. Use mnemonics. Know not just WHAT but WHY.

#2

Backing Maneuver Errors

22% of failures

Problem: Getting outside the boundary, excessive pull-ups, or final position off.

Fix: Learn YOUR reference points. Practice until maneuvers are automatic. Use ALL mirrors.

#3

Lane Position Problems

12% of failures

Problem: Drifting, not staying centered, or improper tracking on turns.

Fix: Keep eyes far ahead, not right in front. Use mirrors to check position constantly.

#4

Intersection Failures

10% of failures

Problem: Not scanning, improper speed, or rolling stops.

Fix: VISIBLY turn your head at every intersection. Count 3 seconds at stop signs.

#5

Improper Shifting

8% of failures

Problem: Grinding gears, wrong gear selection, or coasting in neutral.

Fix: Master double-clutching. Know your shift patterns. Never coast.

Fix: Know posted limits. Practice maintaining steady speed. Anticipate changes.

#7

Turn Signal Problems

Following Distance
