Question juridique clé
Whether the cantonal court made an arbitrary factual finding about the visibility and knowledge of the speed limit.
Solution extraite
No arbitrariness was shown; the findings were not obviously unsustainable.
Motifs extraits
The appellant mainly presented appellatory arguments. The court held that he knew the 100 km/h limit before and during the tunnel and that, even if the post-exit signs were not immediately readable, this did not undermine the decisive findings.
