Questão jurídica principal
Whether the cantonal court's fact-finding was arbitrary because it ignored alleged confusion and defects in the temporary speed limit sign.
Decisão extraída
No arbitrariness: the omitted circumstances were not legally relevant enough to affect the outcome, and the driver still had to obey the sign as displayed at the relevant time.
Fundamentação extraída
The temporary limit was shown as 80 km/h when the vehicle was measured; even an irregular or unclear sign must generally be respected because it creates a legally protected appearance for other road users, except in truly exceptional cases not present here.
