Question juridique clé
Whether the cantonal court had to order a medical fitness-to-drive examination and consider a preventive measure.
Solution extraite
Given the very high alcohol level, especially in light of the two earlier alcohol-related withdrawals, a fitness-to-drive examination had to be ordered ex officio.
Motifs extraits
A reading close to 2.5‰, combined with the history of repeated very high alcohol levels, could indicate alcohol dependence; the authority must clarify the situation in every case before deciding on a security withdrawal.
