Key legal question
Whether the conviction for misuse of plates and simple traffic-rule violation should be overturned.
Extracted holding
The appeal disclosed no violation of federal law; the conviction stands.
Extracted reasoning
The appellant did not show that the cantonal court had misunderstood the effect of the valid provisional driver's-license withdrawal or erred in refusing to rely on private medical opinions. His attacks on the speed findings were largely inadmissible criticism and did not establish arbitrariness under Art. 97 BGG or Art. 9 BV.
