Road Tests and Practical Assessment
What the Class 1 road test contains
SGI's Class 1 practical assessment is a pass/fail evaluation in a tractor-trailer that meets the test-vehicle requirements: registered, insured, mechanically sound, and representative of the class. It normally has three parts: a pre-trip inspection, a yard/backing component, and an on-road drive. The examiner is looking for systematic habits, not memorized phrases.
Pre-trip and yard
- Walk-around inspection in a fixed sequence: lights, tires, wheels, brakes, suspension, couplings, hoses, fifth wheel, and cargo securement.
- Air-brake checks: compressor build-up, governor cut-out, leakage limits, low-pressure warning, and spring-brake application.
- Coupling/uncoupling where required: alignment, kingpin lock, landing gear, air lines, electrical cord, and trailer brake test.
- Backing: straight-line, offset, and parking manoeuvres with mirror discipline and a spotter where appropriate.
On-road drive
The examiner scores lane position, speed management, mirror scans, signal timing, right turns and off-tracking, lane changes, railway crossings, grade control, and highway merging. Automatic failures include a collision, examiner intervention, disobeying a traffic control device, or any dangerous action. You must pass every component; a failed pre-trip can end the test before the drive begins.
Worked example
A candidate completes a clean highway drive but rushes the pre-trip. He checks the tractor brakes but never tests the trailer spring brakes and misses a cracked air line. The examiner fails the inspection, so the drive is never scored. The lesson: the pre-trip is not a formality - it is a separately scored, high-weight component, and a defect the candidate should have found is treated as a knowledge failure.
Traps
- Rolling stops and wide right turns that clip the curb.
- Not verbalizing what you check during the inspection.
- Using a test vehicle with expired registration or inoperative lights.
- Failing to adjust mirrors and seat before moving.
- Forgetting the trailer brake test after coupling.
