What is the offence of being in charge of a vehicle while over the alcohol limit in Northern Ireland?

“In charge” is broader than driving. The court looks at the real circumstances, including your control of the vehicle, location, keys and the likelihood of driving while still over the limit or unfit.

nidirect lists possible penalties for being in charge while over the limit or unfit as up to three months’ imprisonment, a fine up to £2,500 and possible disqualification, depending on the case.

This is why sleeping in a parked car after drinking can create legal risk. The facts matter, and a person should not rely on the assumption that a stationary vehicle automatically prevents a drink-driving related offence.

The NI enforcement process separates screening from evidential proof. A roadside breath test, DrugWipe or impairment check gives police information and may justify arrest or further testing, but the prosecution is built from the statutory evidential procedure, officer observations and any laboratory or approved-device result. That distinction matters when reading reports of someone having “failed a roadside test”. On the facts covered here, the answer is that it is a separate offence to be in charge of a vehicle on a road or other public place while over the prescribed limit or unfit through drink or drugs, even if police cannot prove you were actually driving. This is one of the areas where the jurisdiction and the exact status of the driver or vehicle matter more than a general UK rule.
