Basic Vehicle Control
Backing, turning, and low-speed maneuvering safely with a vehicle whose blind spots are larger than most cars are long.

Basic vehicle control covers the slow-speed maneuvers that fill the second portion of the CDL skills test: straight-line backing, offset backing left and right, parallel parking on the driver and passenger sides, and an alley dock. Every maneuver is scored on whether you used pull-ups (limited), encroached on boundary lines, missed the final stop position, or got out of the vehicle to look without a proper GOAL (Get Out And Look) sequence with hazard lights on and the parking brake set.
The FMCSA CDL Manual emphasizes three habits. First, always back to the driver\'s side when you have a choice; visibility is dramatically better than passenger-side blind backing. Second, GOAL is free — there is no points penalty for getting out and walking around the rear of the trailer to confirm clearance. Third, use a steady speed at idle in low gear and steer with small, deliberate corrections; oversteering during backing is the most common cause of trailer jackknife at low speed.
Right-hand turns at intersections require swinging slightly left first to avoid the trailer cutting the curb, but never so far that another driver can squeeze up your right side. Left turns require entering the intersection in the leftmost legal lane and exiting into the corresponding lane on the receiving street so the trailer tracks within its own lane. Off-tracking — the difference between the path of the steering axle and the path of the trailer axles — is the underlying physics that drives both turning and backing technique. Memorize the term and the geometry; both come up on the written exam.
