6 Mistakes That Cause Most Failures
Not using reference points for backing
Fix: Ask your instructor for specific mirror reference points
Rushing through pre-trip
Fix: Take your time - examiners want thoroughness, not speed
Not scanning intersections
Fix: Turn your head visibly - examiners need to see you look
Poor lane positioning
Fix: Stay centered, watch for drift on turns
Forgetting to cancel turn signals
Fix: Build the habit of checking after every turn
Getting out of cab wrong
Fix: 3 points of contact ALWAYS when entering/exiting
