It is an offence to be drunk in charge of a motor vehicle rather than driving it. Each offence turns on its own facts and could include a driver sitting in the vehicle with the key in the ignition person but the prosecution has to prove an intention to drive. There is a statutory defence to this charge if you can show that at the time the offence there was no likelihood of you driving the motor vehicle whilst unfit.
The Court has powers of imprisonment of up to 3 months or there can be a financial penalty of up to £2,500. The Court can endorse your driving licence with a maximum of 10 penalty points.The Court has a discretion to disqualify you if the particular circumstances were aggravated, such as a very high reading of alcohol in your body.
