Drivers could face penalties or even disqualification without turning on the ignition whilst under the influence of alcohol. Whilst numerous motorists might assume prosecution for drink-related driving offences requires the engine to be running and the vehicle in motion, legislation dictates otherwise.
The Road Traffic Act 1988's Section 4 (2) stipulates it is illegal to be "in charge of a mechanically propelled vehicle which is on a road or other public place" whilst being "unfit to drive through drink or drugs".
Police typically classify this as a DR50 driving violation, which prosecutes individuals for being in control of a vehicle while above the legal alcohol limit. Fines for DR40 and DR50 convictions. Offence codes are utilised by the DVLA and police to categorise driving violation
