Which Northern Ireland driving licence restriction codes can require specific vehicle adaptations?

Northern Ireland licences can carry restriction codes identifying conditions such as automatic transmission or specific modified controls.

The exact code depends on the driver’s assessed needs and the type of adaptation DVA requires; there is no single “disabled driver” code that covers everyone.

For “Which Northern Ireland driving licence restriction codes can require specific vehicle adaptations?”, the wider Northern Ireland context is this: Northern Ireland licensing in these cases is handled by DVA, not DVLA. Age or disability alone does not decide whether someone may drive: the key questions are licence validity, medical fitness, any DVA restrictions and, for Blue Badge matters, the specific parking scheme rules. Current nidirect/DVA guidance should therefore be checked rather than assuming Great Britain procedures are identical.

For this exact question — “Which Northern Ireland driving licence restriction codes can require specific vehicle adaptations?” — the practical point is: Read the codes printed on your licence and make sure any vehicle you drive satisfies them. The answer should be applied to the actual signs, conditions, licence wording or parking rules in force at the time, because temporary restrictions and individual DVA decisions can change the ordinary position.

If the rule, road layout or personal licence condition changes, those primary sources are the ones to re-check.
