Abstract
An interlock system for a vehicle includes a sampling device (4) that receives a sufficient quantity of a body fluid sample from a person to be tested; a read-out unit (11) detecting substances that are contained in the body fluid sample; and an evaluating unit (2) evaluating the substances detected by the read-out unit (11), so that respective concentrations of the detected substances can be obtained. The detection and evaluation of the substances in the body fluid is effected by chemical, immunochemical, enzymatic, electrochemical or optical analytical methods. The quantity of body fluid delivered by the person to be tested is automatically detected and monitored. A control device (1) is coupled to the evaluating unit (2) and prevents the start process of the vehicle if an insufficient quantity of body fluid is present or if at least one of the substance concentrations is above a predetermined concentration limit value.
