An interlock system for a vehicle includes a sampling device () that receives a sufficient quantity of a body fluid sample from a person to be tested; a read-out unit () detecting substances that are contained in the body fluid sample; and an evaluating unit () evaluating the substances detected by the read-out unit (), 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 () is coupled to the evaluating unit () 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.

Drug interlock system having a safety function

An interlock system () for a vehicle is provided with an alcohol tester (), which is designed to measure the alcohol level of a driver of the vehicle. A control device () is coupled with the alcohol tester () and is designed to make it possible to start the vehicle or to prevent the vehicle from being started depending on the measured alcohol level. A transceiver module () is coupled with the control device () and is designed to send data to a remotely located control system in a wireless manner or to receive data from said control system in a wireless manner. The transceiver module () is designed, furthermore, to release the control device () in response to data received in a wireless manner in order to make it possible to start the vehicle regardless of the operating state of the control device.
