Towing Laws in Oregon: What Drivers Need to Know

Whether you’re towing a utility trailer for work, hauling a camper through the Cascades, or helping a friend move, it’s important to understand Oregon towing laws before hitting the road. Oregon has clear regulations around weight limits, trailer lighting, safety equipment, and licensing—designed to keep everyone safe.

This guide breaks down the most important towing laws in Oregon to help drivers stay compliant and avoid costly mistakes.

Trailer Weight and Towing Capacity

Know Your Limits

Oregon follows both federal and state standards when it comes to trailer weights and towing capacity. The combined weight of your vehicle and trailer cannot exceed the Gross Combined Weight Rating (GCWR) set by the manufacturer.

For safety and legal reasons, always check:

• Your vehicle’s owner's manual for towing capacity
• The trailer’s Gross Vehicle Weight Rating (GVWR)
• The loaded weight of your cargo

When Brakes Are Required

Oregon law requires trailers to have brakes if:

• The trailer’s loaded weight exceeds 1,500 lbs, or
• The trailer’s weight exceeds 40% of the towing vehicle’s weight

If the trailer does require brakes, they must be adequate to stop and hold the trailer on any grade.

Lighting and Visibility Requirements

Proper lighting is essential—not only to meet legal requirements but also to stay visible and safe on Oregon’s highways, mountain passes, and rainy roads.

Required Trailer Lights in Oregon:

• Tail lights (visible from 500 feet)
• Brake lights
• Turn signals
• Reflectors on sides and rear
• License plate light

All lights must be operational, even during daylight hours in poor visibility.

Safety Chains and Hitching Rules

Safety chains are required on all towed trailers in Oregon. The chains must be crossed underneath the tongue of the trailer and strong enough to keep the trailer connected in the event of a hitch failure.

Other Hitching Requirements:

• Trailer coupler and hitch must be rated for the load being towed
• Hitch ball and coupler must be compatible and properly secured
• A locking mechanism or pin must be used to secure the ball mount to the receiver

Licensing and Registration

Do I Need a Special License to Tow in Oregon?

In most cases, a standard Class C license is sufficient for towing personal trailers or campers. However, if the combined weight of the vehicle and trailer exceeds 26,000 lbs or if you are towing for commercial purposes, you may need a commercial driver’s license (CDL).

Trailer Registration Requirements:

Oregon requires all trailers with a loaded weight over 1,800 lbs to be titled and registered. The DMV issues special trailer plates for registered trailers.

Speed Limits and Driving Rules

Oregon’s posted speed limits apply to towing vehicles unless otherwise noted. However, when towing, drivers should:

• Reduce speed during poor weather or steep grades
• Leave extra following distance
• Stay in the right lane when possible
• Avoid sudden lane changes or braking

Violations while towing can lead to higher fines and increased insurance rates.

Parking and Storage Regulations

When not in use, trailers must be parked in compliance with local ordinances. In many Oregon cities:

• Street parking for unattached trailers is limited or prohibited
• RVs and trailers may require permits for overnight parking
• Trailers should not obstruct sidewalks or driveways

Always check with your city or county for specific trailer parking regulations.

Penalties for Violating Oregon Towing Laws

Failure to comply with Oregon’s trailer towing laws can result in:

• Fines and citations
• Impoundment of the trailer
• Liability in the event of an accident
• Points on your driving record

Don’t take shortcuts—invest in proper equipment, follow the rules, and inspect your trailer regularly.
