Understanding Arizona Towing Laws

Whether you're hauling a trailer across the desert or towing a boat up north for the weekend, understanding Arizona towing laws is essential to staying safe and legal on the road. From Phoenix to Flagstaff and Tucson to Yuma, each region sees its fair share of towing activity, especially in Arizona's RV-friendly and adventure-loving landscape.

This guide covers everything you need to know about towing regulations in the Grand Canyon State.

Licensing & Towing Capacity Requirements

Driver’s License Requirements

In Arizona, a standard Class D driver’s license is generally sufficient for towing most non-commercial trailers. However, if the trailer's Gross Vehicle Weight Rating (GVWR) exceeds 10,000 lbs, or if the combined weight of the vehicle and trailer is more than 26,000 lbs, a commercial Class A or B license may be required.

Vehicle Towing Capacity

Trailer Equipment Requirements

Brakes

Arizona towing laws require brakes on all trailers with a GVWR of over 3,000 lbs. These brakes must be in working order and properly adjusted.

Safety Chains

Safety chains are mandatory. Arizona law specifies that every towed trailer must be connected to the towing vehicle using two safety chains or cables that are strong enough to hold the weight of the trailer in case of hitch failure.

Lights & Reflectors

Every trailer must have:

• Two red tail lights visible from 500 feet
• Brake lights
• Turn signals (if your towing vehicle’s lights are obscured)
• At least two red reflectors on the rear
• Clearance lights for trailers wider than 80 inches

Make sure your trailer wiring is functional and connected properly to your tow vehicle’s lighting system.

Size & Weight Limits in Arizona

Length

• Maximum length for a trailer: 40 feet
• Maximum combined length for vehicle + trailer: 65 feet

Width

• Maximum allowable trailer width: 102 inches (8.5 feet)

Height

• Maximum trailer height: 13 feet 6 inches

Triple Towing

Triple towing (e.g., towing a boat behind a fifth-wheel RV) is legal in Arizona, but the total length must not exceed 65 feet, and each unit must be securely attached and comply with safety regulations.

Speed Limits and Towing Etiquette

Speed Limits

• The maximum towing speed in Arizona is 65 mph, even if posted limits are higher.
• Reduce speed on steep grades, curves, or in poor weather conditions.

Lane Usage

Towed vehicles are required to use the right lane, or the right two lanes on highways with three or more lanes. Passing must be done only when it is safe and legal.

Parking and Trailer Storage

City Ordinances

Cities like Phoenix, Mesa, Scottsdale, and Tucson may have their own ordinances on where trailers can be parked, especially in residential zones. In most cases, trailers cannot be parked on city streets overnight.

Storage Considerations

If you live in a neighborhood with an HOA (Homeowners Association), check local rules regarding visible trailer parking on driveways or in yards.

Penalties for Violations

Violating Arizona towing laws may result in:

• Fines starting at $100 or more
• Towing of your vehicle/trailer by law enforcement
• Points on your driving record
• Increased insurance rates
• Legal liability if an improperly towed trailer causes an accident
