Why Heavy Vehicles Need a Certificate of Fitness, Not a WOF

If you are used to running cars, the Warrant of Fitness is familiar territory. Step up to trucks and the rules change. Any vehicle over 3,500kg needs a Certificate of Fitness rather than a WOF, and it is a stricter, more commercial inspection for a reason.

A COF looks hard at the systems that carry real load: the brakes, the chassis and structure, the steering, the lights, and the safety equipment. Because a loaded truck takes far longer to stop and does far more damage if something fails, the standard is higher and the checks are more detailed. Most heavy vehicles need a COF every six months, though some can qualify for a longer cycle.

The smart move is not to wait for the inspection date to roll around. A pre-COF check lets you find and fix problems on your own timeline instead of scrambling when something fails. That keeps your trucks legal, your drivers safe, and your operation running without an unexpected stand-down. If you are not sure when your COF is due or what it covers, ask and we will walk you through it.
