Post driving consumption
In rare circumstances after having driven a vehicle (and often after a collision) people drink extra alcohol and then are arrested for drink driving. This is often referred to as a “hip flask defence”. As suggested above there are often periods of time where the police are not yet involved with an offence where people continue to drink, often to calm themselves after an incident. If it can be proven to the satisfaction of the court that the alcohol level before the extra alcohol would have been below the legal drink driving limit then a not guilty verdict will be given. Experts opinions are crucial in this type of defence and a record of what was consumed will also be critical.
