The Federal Motor Carrier Safety Regulations (Title 49, Parts 350-399) govern all vehicles engaged in interstate traffic.
There are some situations where a tractor-trailer or other commercial motor vehicle is involved in only intrastate travel. For example, an appliance store in Phoenix may own a truck that only makes in-state deliveries.
The Arizona Department of Public Safety has adopted Title 49, Parts 382-384 and 390-399 of the federal regulations.
Driver Qualification
Arizona has adopted Part 391 of the Federal Regulations with the
exception of Secs 391.1 (b)(1), 391.68, and 391.69. The physical qualification requirements also contain special provisions. However, the driver of an intrastate-operating tow truck with a GVWR of up to 26,000 pounds is exempt from part 391 with the exception of Secs. 391.41, 391.43, 391.45, 391.47, and 391.45.
Driving of Motor Vehicles
Arizona has adopted Part 392 of the Federal Regulations.
However, Part 392 was not adopted for an intrastate-operating
tow truck that has GVWR or up to 26,000 pounds.
Recording and Reporting of Accidents
Arizona has adopted Part 390, which includes accident record keeping requirements. One notable difference, however, is that Part 390 was not adopted for an intrastate-operating tow truck that has a GVWR of up to 26,000 pounds.
