Question juridique clé
Whether the factual basis for an indefinite precautionary driving-license withdrawal was sufficient
Solution extraite
The cantonal findings were insufficient because the medical assessment did not include a proper traffic-psychological/psychiatric evaluation of the appellant's alcohol problem and driving attitude.
Motifs extraits
A pathological CDT value alone is not enough for an indefinite withdrawal. Given the serious sanction, thorough medical-psychiatric clarification was required, and the existing examination was too cursory.
