Can DVA refuse to test a vehicle presented for an MOT in Northern Ireland?

Yes. DVA can refuse to conduct an MOT where the vehicle is presented in a condition that makes a safe or proper inspection unreasonably difficult.

Examples include a vehicle that is excessively dirty or unhygienic, or certain modified/very low vehicles that cannot be safely accommodated without prior arrangements.

For DVA testing, keep the booking confirmation, test certificate or refusal notice and note any deadlines. An MOT result only confirms the condition of testable items at the time of inspection; the keeper and driver remain responsible for roadworthiness at all times. For "Can DVA refuse to test a vehicle presented for an MOT in Northern Ireland?", keep the document that records the original test decision because DVA procedures often depend on the date and status shown on it.
