Miscellaneous

Bulldozer blades and arms exceeding 14′ in width, measured at right angles to the trailer axis, must be detached and transported to ensure safety. Dozer blades narrower than 14′ may be transported without detachment if the dozer is securely supported. Easily removable components such as buckets, blades, and counterweights should be removed; however, they can be transported with the load. Blades can be detached and transported on the same trailer if the load would be overweight with or without the blade, but this must be specified in the permit. Wide loads require side mirrors extending sufficiently to maintain visibility.

Signs, Flags & Lights for Arizona Oversize Load Permits

All vehicles or loads wider than 9′ must display “Oversize Load” signs. Overwidth loads and vehicles must be flagged with red flags (12″ square or larger) on extremities. Front or rear overhangs must be flagged or illuminated. Up to 10′ overhang is permitted at night but must be lit and flagged. Overheight or overweight-only loads do not require signs or flags.

Note on Arizona Oversize Permits: Arizona scales expect permit weights to closely match actual weights and dimensions. Permits can be obtained at the scales to ensure accuracy, preventing potential issues.
