Basic Control of Your Vehicle

Basic Control of Your Vehicle

This domain tests starting, shifting, steering, stopping, and backing. The exam rewards smooth inputs, correct gear selection, and a careful check before you move.

Starting and moving

Adjust the seat and mirrors, fasten the belt, and check that the path is clear. Start in the proper gear, release the parking brake, and accelerate smoothly. Do not roll backward on a hill.

Shifting and steering

Use progressive shifting and do not coast in neutral. Downshift before a downgrade or a curve rather than braking late. Keep both hands on the wheel and avoid shifting while turning. Look ahead and steer smoothly; jerky inputs unsettle a tall vehicle.

Backing and stopping

Get out and check the area before backing. Use a spotter when possible, back slowly, and stop if you lose sight of the spotter. Back toward the driver's side when you can. For stopping, brake early and smoothly, and avoid locking the wheels.

Worked example

You are backing a straight truck to a loading dock and the spotter disappears behind the trailer. Do not continue on memory. Stop, set the brake, and reestablish visual contact or check the area yourself.

Traps that cost marks

  • Coasting in neutral to save fuel.
  • Shifting in the middle of a turn.
  • Backing without checking behind the vehicle.
  • Braking hard in a curve instead of slowing before it.
