Questione giuridica chiave
Whether the collision constituted a medium-severe traffic offense under Art. 16b LCStr rather than a minor offense.
Decisione estratta
The conduct was a medium-severe offense because the driver failed to keep sufficient distance and adapt speed, creating more than a minimal danger.
Motivazione estratta
Rear-end collisions at highway speed are not ordinarily minimal-risk events; the driver did not notice the slowing traffic in time and could have caused a domino effect in dense traffic.
