Race car trailer insurance is one of the most underestimated line items in a drag racer’s budget. Racers will spend months researching modified car insurance and ignore the $20,000–$60,000 trailer sitting behind it entirely.

This guide gives you real-world cost benchmarks, explains the factors that move the premium, and shows you how to get the most coverage for your money.

The figures below are based on market rate research for US-based policies covering a single trailer used for drag racing events, towed by an insured vehicle, stored at a residential address.

Premium Benchmarks by Trailer Type and Value

Open Trailers

• Under $5,000 value: $80–$150/year
• $5,000–$10,000 value: $120–$220/year
• $10,000–$20,000 value: $180–$320/year

Enclosed Trailers

• $10,000–$20,000 value: $200–$380/year
• $20,000–$35,000 value: $320–$580/year
• $35,000–$60,000 value: $480–$850/year
• $60,000+ (custom build or living quarters): $750–$1,500/year

What Drives the Price Up

Contents Coverage

Adding contents coverage — for tools, tyres, spare parts, safety equipment, and fuel handling gear — is the single biggest optional cost driver. Expect a $10,000 contents rider to add $50–$150/year. A $25,000 contents rider (covering a full set of spare tyres, a transmission, and a significant tool collection) can add $150–$400/year.

Important: the race car inside the trailer is not contents — it’s a separately insured vehicle. Contents coverage applies to equipment and parts, not the primary race vehicle.

Track / Event Use

Some base trailer policies exclude coverage while the trailer is at a racing event — particularly for theft during an overnight stay at a track facility. Adding a track or event endorsement typically costs $50–$150/year and is worth having if you do overnight events.

Geographic Rating

Policies are rated by the state where the trailer is garaged. States with higher theft rates (California, Texas, Florida) attract higher premiums than rural Midwestern states. The difference can be 20–35% on the same trailer value.

Deductible

Standard deductibles on trailer policies range from $500 to $2,500. Choosing a $2,500 deductible instead of $500 typically reduces annual premium by 15–25%. For a trailer you own outright (no lien), a higher deductible is often the right choice.

How to Keep Costs Down

1. Bundle with your modified car policy — ask your specialist insurer if they can schedule the trailer on the same policy. Combined policies often carry a multi-item discount.
2. Use stated value rather than agreed value — agreed value pays out the full insured amount in a total loss; stated value policies can depreciate the payout. Stated value is cheaper. For a trailer under 5 years old, agreed value is worth the extra cost. For an older trailer, stated value may be adequate.
3. Choose a higher deductible — if you can absorb a $2,000–$2,500 loss, take the higher deductible and reduce your annual premium.
4. Accurately value contents — don’t over-insure contents. If you only carry $3,000 in tools and spare parts, don’t insure for $15,000. Over-insuring wastes premium without improving coverage (insurers pay actual cash value at claim, not the insured limit).
5. Store in a locked structure — some insurers discount premium for trailers stored in a garage or secured storage facility versus street parking.

Who Offers Race Trailer Insurance

Not all insurers write race trailer coverage, particularly for high-value enclosed trailers used at racing events. The most reliable options:

• National General — strong trailer specialist, competitive rates, covers specialty trailers
• Progressive Commercial — broad trailer coverage, often competitive for higher-value enclosed trailers
• National Trailer & RV Insurance (ntitrailer.com) — specialist trailer insurer with race and hauler endorsements
• Your existing specialist car insurer — Hagerty, Grundy, Traction Insurance, and similar specialists can often schedule a trailer alongside your race car policy
