The vehicle must remain fit for the road
Roadworthy means that the vehicle complies with the prescribed condition and equipment requirements. A licence disc records licensing; it does not certify that a tyre damaged this morning or a brake that has just failed is safe. A driver must not knowingly use a dangerous vehicle and an owner must not permit unlawful use.
Use a systematic walk-around and cab check before travel. Look at the vehicle as it will actually be driven, including its passengers, trailer and load. A fault that prevents safe control, visibility, braking or restraint needs attention before the journey, not after a successful first kilometre.
A useful check sequence
Work around the vehicle and then into the driving position so that important systems are not forgotten.
- Outside: check tyres, obvious leaks, secure bodywork, mirrors, lamps, reflectors, plates and anything attached to the vehicle.
- Load and occupants: check fastening, dimensions, unobstructed lamps/view, seats, belts and child restraints.
- Driving position: check clear view, mirror setting, steering freedom and access to pedals or motorcycle controls.
- Function: check the prescribed lamps, horn, wipers, braking controls and speedometer as appropriate.
- Before moving: remove obstacles, make sure the route is clear, and confirm that all doors and carried equipment are secured.
Number plates must remain identifiable
Fit approved plates securely so that they are not easily detached. They must be upright, or within 30 degrees of upright, with the whole plate and every character clearly visible and legible. Do not hide the plate with a rack, load, dirt or an accessory.
The manual requires a rear plate on a motorcycle, motor tricycle or trailer; other motor vehicles require front and rear plates. After adding a trailer or carrier, check the actual rear of the combination and its plate lighting, not only the drawing vehicle.
Decide what a defect means
A loose mirror, ineffective brake or exposed fuel leak affects more than appearance. Ask which safety function has been lost and whether the vehicle still satisfies the rule. Do not compensate for a failed brake by promising to drive slowly or for an obstructed view by asking a passenger to watch constantly.
Use the detailed lessons on lamps, visibility, brakes and steering, tyres, occupant protection and loads to investigate each system. The pre-journey check brings these requirements together; it does not replace the individual rules.
Worked situation
A vehicle has a current licence disc but fuel is dripping near its exhaust. The disc does not make the journey lawful or safe. Keep the engine off, prevent use and arrange appropriate repair before road operation.
