How Much Does Trailer Insurance Cost in Illinois?

How much does trailer insurance cost in Illinois?

Cost depends almost entirely on the type of trailer and how it is covered. A basic utility trailer added as an endorsement to your auto or homeowners policy typically runs $100 to $250 a year. A boat trailer is usually cheapest when bundled with your boat policy, adding roughly $25 to $200 a year. An enclosed or cargo trailer, which carries more value and more risk, usually needs its own policy at $300 to $500 or more a year. A travel trailer or camper generally needs a standalone RV policy, which commonly runs $300 to $600 a year for standard coverage and can exceed $800 to $1,500 a year for a high-value trailer with full coverage.

*Estimates only, based on published 2026 industry consumer guides. Your exact premium depends on the trailer's value, age, and use, how and where it is stored, and your driving record, and is confirmed by a licensed producer.

Do you need insurance for a trailer in Illinois?

Illinois law does require the trailer itself to be registered. Under 625 ILCS 5/3-401, every trailer, semitrailer, and pole trailer driven or moved on an Illinois highway must be titled and registered with the Secretary of State, whether it is a utility trailer, an enclosed cargo trailer, a boat trailer, or a travel trailer, with only a small handful of exemptions.

Insurance is a different question. Illinois does not have a separate state law requiring you to carry a standalone insurance policy on the trailer itself. What the state does require is liability insurance on the vehicle towing it, and that requirement does not go away just because a trailer is attached. If you financed the trailer, your lender may still require physical damage coverage as a condition of the loan, and many marinas, storage facilities, and campgrounds require proof of insurance before they will store or accept a trailer on-site.

Does my auto insurance cover my trailer while I'm towing it?

Partly. In most cases, the liability portion of your auto insurance policy extends to a trailer while it is attached and being towed, so if the trailer causes an accident or injures someone, that liability coverage generally applies. What it typically will not do is pay to repair or replace the trailer itself. Collision and comprehensive coverage on your car or truck almost never extends to a separate trailer, which is exactly the gap that catches a lot of owners off guard after a crash, a rollover, or a theft from a driveway.

Closing that gap usually means either an endorsement added to your auto policy for physical damage to a specific trailer, or a standalone trailer policy, depending on the trailer's value and how often you use it.

Does homeowners insurance cover a stolen or damaged trailer?

Only in narrow circumstances, and usually with a low dollar limit. A standard homeowners policy may provide some coverage for a trailer while it is parked on your own property, typically for specific causes like theft, fire, or vandalism, but that limit is often capped around $1,000 to $1,500. Once the trailer is off your property, being towed, or in storage elsewhere, homeowners coverage generally stops applying entirely.

If your trailer is worth more than a homeowners sublimit would replace, or you use it away from home regularly, a dedicated trailer or RV policy is the more reliable way to actually be covered.

What does a dedicated trailer insurance policy actually cover?

A standalone trailer or RV policy generally includes liability coverage, plus collision and comprehensive protection for the trailer itself against accidents, theft, fire, and weather. For a travel trailer or camper, a policy typically extends further to cover personal belongings inside, like furnishings, electronics, and clothing, and often adds roadside assistance and coverage for permanently attached accessories or awnings. Enclosed cargo trailers can often add coverage for tools or equipment carried inside, which a basic auto or homeowners policy will not touch.

What affects the cost of trailer insurance?

Insurers price trailer coverage based on the trailer's type, age, and value; how often and how far it travels; where it is stored, especially locked and covered versus outdoors; any built-in equipment or upgrades; your driving record; and how much liability and physical damage coverage you choose. Bundling trailer coverage with your auto, home, or boat policy is usually the fastest way to bring the premium down.
