Road Traffic offences – Drink Driving

Public Offences Section Icon

Section 4 of the Road Traffic Act 2010, reduced the drink driving alcohol limits for all drivers. They also differentiate between experienced drivers and new drivers – those with learner permits or who hold a driving licence for 2 years or less, or have no valid licence/permit. Lower alcohol limits apply to new drivers than those that apply to experienced drivers.

The lower alcohol limits applying to new drivers also apply to drivers of buses, lorries, trailers, work vehicles, taxis and other public service vehicle drivers.

The new offences are as follows:

  • An offence of driving or attempting to drive a mechanically propelled vehicle in a public place while under the influence of an intoxicant to such an extent as to be incapable of having proper control of the vehicle.
