Can PSNI require a vehicle to attend a further roadworthiness examination?

Yes. Depending on the defect and enforcement route, a vehicle can be directed for further inspection or prevented from continued use until defects are rectified.

For this Northern Ireland query, the practical issue is whether PSNI require a vehicle to attend a further roadworthiness examination. A roadside stop in Northern Ireland should be treated as a legal compliance check, not as an argument at the roadside. The Highway Code for Northern Ireland states that drivers must obey police stopping signals and stop as soon as it is safe. PSNI can then check the matters for which it has legal powers, including driver entitlement, insurance and vehicle condition.

If stopped, pull over safely, switch off the engine when directed, answer lawful requests accurately and do not give false information. If a database record appears wrong, produce whatever genuine evidence you have and contact the insurer or issuing authority promptly. Disputes about a notice, seizure or alleged offence should be dealt with through the proper review or court process rather than by refusing to comply at the roadside. For this question specifically — “Can PSNI require a vehicle to attend a further roadworthiness examination?” — the safest answer is the one above, based on the current Northern Ireland and UK official guidance rather than forum advice or rules written for another jurisdiction.
