Bonne réponse : B. The maximum safe vehicle height in metres

A low clearance sign lists the maximum vehicle height (e.g., '3.8 m') that can safely pass under the structure. Truck and RV drivers must check their loaded height; a miscalculation tears off the top of the vehicle and damages the structure.
