​

MISCELLANEOUS:

Bulldozer blades and arms over 14′ wide (measured at right angles to the trailer axis) shall be detached and

hauled in a manner to not create a safety hazard

Dozer blades shorter than 14′ wide may be hauled without being detached provided the dozer is firmly supported.

If buckets, blades, counterweights, etc., are easy to remove, they must be removed, but can be hauled with the load.

Blade can be detached and hauled with the dozer on same trailer if the load would be overweight with or without the blade, but it must be stated on the permit.

On wide loads, side mirrors must extend far enough to avoid view being blocked by the load.

 Arizona scales expect permit weights to be very close to actual weights and dimensions.

You can buy the permit at the scales to avoid problems, or else make sure your permitted weight is accurate!
