The police checked, among other things, the qualifications of driving instructors and any imposed driving bans. All students and instructors also underwent alcohol and drug tests. The saliva test serves as a preliminary screening tool and provides an initial indication of possible driving under the influence.

Four students and one driving instructor
No violations were found in Alkmaar. In Haarlem, the tests resulted in five suspicions: four students and one driving instructor tested positive for THC, the active substance in cannabis. Blood samples were taken from all involved for further laboratory analysis. Until it is known whether the THC levels are punishable, they are subject to a 24-hour driving ban.

If the blood test shows that the driving instructor had a punishable amount of THC in their blood, this may affect their instructor qualification. The Institute for Vocational Training and Qualification in the Mobility Sector (IBKI) will make a decision on this.

Motorcycle lessons without required qualification
Additionally, in Haarlem, a driving instructor was fined for giving motorcycle lessons without the required qualification. The police also maintained extra supervision around Schiphol-Rijk, where many motorcycle schools practice for exams. They checked the rule that one instructor may supervise a maximum of two students at the same time. Everything was in order here.

More inspections in the coming period
The police announced that these inspections will be repeated periodically. One reason is a similar inspection last year, where an instructor and her student tested positive for THC and later were found to be above the punishable limit. They stated they had only smoked the day before, but that did not guarantee the substance had left the body. That case was reported to the IBKI, which then took measures.

When laboratory results show a punishable concentration, the traffic officer determines the penalty. Additionally, the CBR receives a report for a possible educational measure or a driving fitness investigation.

Unacceptable risk
With these repeated inspections, the police want to make clear that driving under the influence, even during driving lessons, poses an unacceptable risk to traffic safety and is therefore tackled firmly.
