Question juridique clé
Whether the preventive ban on using the foreign driving licence in Switzerland was lawful.
Solution extraite
Yes. Serious doubts about driving fitness justified a preventive prohibition under the traffic admission rules.
Motifs extraits
The applicant admitted to drinking heavily and did not dispute the serious doubts raised after the September 2006 incident. Those doubts were sufficient to justify a preventive withdrawal or, for a foreign licence, a ban on its use in Switzerland.
