Preventive withdrawal (LCR 15d), like safety withdrawal, is intended to protect other road users. But unlike the latter, preventive withdrawal can be pronounced when the authority has simple doubts about a driver’s aptitude to drive (i.e. without an expert opinion).
It also means that the driver is not able to determine what withdrawal is made.
This is an indefinite licence withdrawal. Once the assessment is completed, if it is determined that the driver is unfit to drive, a safety withdrawal will be issued. Conversely, if the expert opinion concludes that the driver is fit to drive, the licence withdrawal ends.
A preventive withdrawal is, by law, mandatory when the driver :
- Driven despite a blood alcohol content while driving of 1.6 ‰ grams of alcohol per liter of blood (0.8 mg per liter of exhaled air, LCR 15d al. 1 lit. a)or
- driving under the influence of drugs (regardless of the amount measured) (LCR 15d para. 1 lit. b).
