Being pulled over by the police and asked to provide a breath sample is one of the most intimidating and frightening experiences a driver can face. In that stressful moment, under the flashing blue lights, it is easy to feel powerless and to assume that a conviction is inevitable. However, it is vital to understand that the police must follow a strict, detailed, and technical legal procedure when investigating a drink driving allegation. A failure on their part to follow this procedure correctly can often lead to a successful defence.

Understanding this process is the first step toward protecting your licence and your rights. This guide will break down the procedure step-by-step, from the roadside stop to the evidential test at the police station, highlighting where your rights must be protected and where critical errors can occur. When you are facing an allegation of this gravity, you need a legal team that knows this procedure inside out. At Motoring Defence, our specialist drink driving solicitors meticulously scrutinise every action the police take to ensure your rights were upheld and to build the strongest possible defence.
