Roadworthiness Inspection with Safety-Critical Defects
You are performing a periodic roadworthiness inspection on a 2013 sedan. The owner needs a pass certificate today because the registration expires at midnight. Inspection findings: front brake pads 2 mm on the left inner pad and 5 mm on the outer; left front rotor measured at 24.0 mm against a minimum of 26.0 mm; the right front tyre has exposed cord on the inner sidewall; the steel brake line above the rear axle has heavy surface corrosion with pitting over 150 mm; the parking brake holds on a 12% slope only at the last two clicks. The owner says a friend's workshop 'would pass it' and offers to pay cash for the certificate without repairs. Your inspection station is audited by the transport authority and uses a digital record that uploads immediately.
1. State the inspection result and justify each defect in roadworthiness terms.

The vehicle must fail. The left front inner pad at 2 mm is at or near the replacement limit and is wearing unevenly compared with the 5 mm outer pad, indicating a sticking caliper or slide. The left rotor at 24.0 mm is below the 26.0 mm minimum, so it cannot safely dissipate heat and may crack. Exposed cord on the right front tyre means the structural reinforcement is visible; the tyre is unroadworthy and may fail suddenly. Heavy pitting on 150 mm of brake line above the rear axle is a corrosion perforation risk and a hydraulic failure risk. The parking brake holding only at the last two clicks on a 12% slope shows insufficient reserve. These are safety-critical defects, not advisory items, so no certificate can be issued.
2. What would you tell the customer, and what would you record?
Read the worked answer
Tell the customer clearly and without jargon that the car is not roadworthy and should not be driven, particularly because of the tyre cord and brake line. Provide a written report with measured values, photos and the specific minimum specifications. Offer a repair estimate and a re-inspection appointment. Record the customer's decision, including any refusal to authorise repairs, and note that they were advised not to drive. Because the digital record uploads immediately, the fail result is already recorded; do not alter it. The reasoning: the inspector's duty is to the safety of the vehicle occupants and other road users, and the record must be contemporaneous and accurate in case of an audit or a later collision investigation.
3. The owner offers cash to issue a pass. What do you do?
Read the worked answer
Refuse. Issuing a pass for cash would be a false certification, an offence under the inspection scheme and a serious safety risk. Explain that the digital record has already uploaded and that the station is audited, so no one can change the result. Offer the repair path and a re-inspection; if the customer becomes aggressive, end the conversation and involve the manager. Document the offer in the job record. The reasoning: the integrity of inspection depends on not trading safety for payment, and the audit trail makes falsification detectable and career-ending. A refusal also protects the shop's approval to inspect.
