Hip flask defence

From Wikipedia, the free encyclopedia

In places like the United Kingdom, a hip flask defence is a defence to an allegation of drunk driving that a driver had consumed alcohol between the time of a vehicular offence (such as an accident) and a breathalyser test so that a positive result does not actually indicate that they were driving while intoxicated.

Though popular (in 1991, the defence was used in 90% of Swedish appeals against drink driving convictions),[1] the hip flask defence is not always effective. It is possible to back calculate the amount of alcohol and prove an offence nevertheless.[2]
