Panneaux routiers

Panneau routier de Colombie-Britannique — Merge into the open lane before the closure
Afficher la réponse et l'explication
Bonne réponse : B. Merge into the open lane before the closure

Merge early to avoid last-second squeezing. Late merging where the lane ends is the classic cause of road rage and close calls.
