"Continuous travel" means to operate a vehicle continuously throughout any 24-hour period. These vehicles must abide by the curfew around the large metropolitan areas.

Motor carrier fees are $48 per trip for over 50 miles, and $12 per trip of 50 miles or fewer. The fee for use fuel is $65 per trip for over 50 miles traveled, and $16 per trip for 50 miles or fewer.

To move a used mobile home originating in Arizona, a 504 tax clearance (ad valorem) must be obtained from the county assessor in which the mobile home is located. When a new home is moved from the factory or dealer lot, a bill of lading will be allowed to make this move. Mobile homes originating from out of state are not governed by this restriction. Only Arizona transporter plates are recognized for the movement of the mobile home. If the transporter does not have Arizona transporter plates for the home, a 30-day general-use registration must be purchased to make this move. The cost of this permit is $15.
