Work-truck safety depends on the complete working vehicle: its load, installed equipment, driver visibility, condition, and the people around it. A truck that is within its overall weight rating can still have an overloaded axle, unsecured tools, or a blind area that hides a worker. Safe road travel and safe operation at the site require separate checks.
The useful approach follows the job from loading to arrival, equipment use, and departure. Confirm the limits of the finished truck, control movement of loads and people, and use the procedures for the particular body and attachments. A camera, warning alarm, or heavy-duty badge addresses only part of that picture.
