Questione giuridica chiave
Whether the driver’s refusal to undergo a blood test justified a driving licence withdrawal.
Decisione estratta
Yes. Refusal of the blood test independently triggers licence withdrawal, regardless of his claim that he had not driven while intoxicated.
Motivazione estratta
The withdrawal was based on refusal to submit to the blood test, not on proving drunk driving. The test was needed to clarify whether he had been intoxicated while riding, especially given his later alcohol consumption at home.
