Heavy vehicle CoF with brake and load-security failures
A 2014 Isuzu FTR 850 tipper with a GVM of 15,500 kg arrives at a CoF inspecting organisation for its six-monthly certificate. It is used to cart metal and has a current RUC distance licence. The inspector finds: the air-brake low-pressure warning buzzer does not operate when the ignition is switched on; a roller brake test shows service brake efficiency of 42% and park brake 18%; the left drive tyre has 1.6 mm tread on the outer groove; two load-binding ratchets are cracked; the driver's seat mounting has a loose bolt. The operator says the truck is needed for a concrete pour tomorrow and asks the inspector to issue the CoF and note the defects for next time. The inspector is the only CoF inspector on site.
1. Can the inspector issue a CoF? Assess each defect against the CoF requirements.
Read the worked answer
No CoF can be issued. A CoF is a fitness certificate, not a deferred-repair note. The air-brake low-pressure warning is a required safety device; if it does not operate, the vehicle fails. Service brake efficiency of 42% is below the VIRM minimum for this heavy vehicle class (50%), and park brake performance at 18% must also be checked against the minimum; both are fail items. The drive tyre at 1.6 mm is above the 1.5 mm tread minimum, so tread depth alone is not a fail, but the tyre must still be rejected if it has cuts, bulges or cord exposure. Cracked load-binding ratchets mean the load restraint system is not fit for purpose and is a fail. A loose seat mounting is a safety failure. The operator's deadline does not change the criteria.
2. What should the inspector do next, including recording and notification?
Read the worked answer
The inspector should record a CoF fail with each defect, the brake test figures and the tyre measurement. The vehicle should not be certified until all fail items are repaired and re-inspected. The inspector should advise the operator that the vehicle must not be used for the concrete pour unless it is repaired and passes; using it in an unsafe condition may breach the operator's duties. If the inspecting organisation's procedures require a defect notice or entry in the CoF system, that must be completed. The inspector should not issue a pass conditional on later repair. Any attempt to pressure the inspector should be documented and, if necessary, escalated to the inspecting organisation's compliance manager and NZTA.
