Abstract Device and method for providing a breath sample with a breath-alcohol interlock device A device to prevent the starting of a vehicle comprising a breath gas analyser (5) that is arranged inside the vehicle and is designed to measure the breath alcohol content of an operator is to be improved in such a way lU that a repeat test can be performed without it having a negative impact on the operator. To meet this object a control unit (1) is provided, which is connected to the breath gas analyser (5), the movement sensor (4) and an ignition system (3) of the vehicle, and which requests a 15 breath alcohol test at a pre-determinable time tw in such a way that the breath alcohol test takes place with the vehicle at a standstill, in which the control unit (1) is also designed to preset a time interval as latency time t,, starting from the time t, within which the vehicle must be brought to a standstill.
