During a police operation at the CBR in Den Bosch on March 21, 2025, two driving instructors and six students were found to be driving under the influence of drugs. A total of 350 drug tests were administered, with immediate breathalyzer or blood tests conducted for positive initial results, supported by two police doctors. The instructors, whose licenses and IBKI-validity were also checked, received immediate driving bans, and their cases will be handled by the Public Prosecution Service, with potential revocation of their driving licenses. Additional violations included three instructors receiving citations for not presenting their licenses, a warning for an expired student ID, and one instructor being reprimanded for using a phone while driving.
