Your score is

Trucks are taller and wider than most vehicles, making it essential to know your vehicle’s height and width at all times. Always check for overhead obstructions such as bridges, overpasses, and signs, and be aware of side clearances when passing, turning, or maneuvering in tight spaces. Failing to ensure proper clearances can lead to accidents, costly damage, and legal penalties. Safe clearance practices are fundamental for protecting public safety and maintaining professional driving standards.
