In connection with a police patrol stopping a car for a check of the driver, suspicion of drunk driving arose.
The driver was made to blow into a sifting instrument which resulted in the suspicion arising.
Thereafter the driver was to accompany the patrol to the police station for further sampling in a proof instrument (which is called an evidencer) and further investigation.
During week 19, the police have a national traffic week with the purpose of detecting crimes on the road.
