Your pre-trip is graded before you ever start the engine. Examiners want to see a methodical, walk-around inspection that demonstrates you understand the vehicle — not a memorized speech. Below is the sequence we teach in our MELT program, broken down into the seven inspection zones the MTO uses.
Zone 1: Front Of The Tractor
- Check headlights, signal lights, and high-beam operation
- Inspect windshield for cracks larger than 12mm in the wiper sweep area
- Confirm wiper blades are intact and washer fluid is full
- Look under the front for fluid leaks
Zone 2: Driver Side Engine Compartment
- Engine oil level on the dipstick
- Coolant reservoir level and condition
- Power steering and washer fluid reservoirs
- Belts for fraying, glazing, or missing chunks
- Hoses for bulges, cracks, or leaks at the clamps
Zone 3: Driver Side Saddle Tank, Steer Axle, And Frame
This zone trips up more students than any other. You need to physically check the steer tire tread depth (minimum 3mm in any major groove), look for cuts or sidewall damage, confirm lug nuts are seated and rust-free, and inspect brake components — slack adjusters, air chambers, and hoses.
Zone 4: Rear Of Tractor And Coupling
- Fifth wheel: jaws closed and locked, kingpin seated, no daylight between trailer and plate
- Locking jaw arm in the secured position
- Glad hands and electrical pigtail securely connected
- Mud flaps present, not torn
Zone 5: Trailer Sides
- All marker lights operational and clean
- Tandem locking pins fully seated
- Tire condition and inflation on all axles
- Frame rails free of cracks or rust damage
Zone 6: Rear Of Trailer
Brake lights, signal lights, ABS indicator, and reflective tape all get checked. Make sure the rear doors are properly latched and the licence plate is visible and lit.
Zone 7: In-Cab Inspection And Air Brake Test
After the walk-around, the in-cab portion covers gauges, warning lights, mirrors, seatbelt, horn, defroster, and the full air brake test sequence: governor cut-in and cut-out, applied leak test, low air warning, and spring brake activation. Examiners listen specifically for you to verbalize each step.
We dedicate 17 hours of MELT training specifically to vehicle inspection. By the time you reach your road test, the seven-zone walk-around becomes muscle memory.
