What Is Symbol 31 in Auto Insurance

What Symbol 31 Means in Auto Insurance

Symbol 31 in auto insurance is a symbols designation that limits coverage to specifically described autos listed by their vehicle identification number in the policy declarations. It is one of the ISO symbol codes used in commercial auto insurance forms, and it means the insurer will only cover the vehicles you have explicitly named, not any other autos the named insured might own or use.

How Symbol 31 Differs from Other Symbol Codes

Auto insurance symbol codes tell you which autos are covered under a given coverage part. Symbol 31 is narrow by design. Symbol 1 provides any-auto coverage for the named insured, while Symbol 31 restricts coverage to the listed autos only. This distinction matters because Symbol 31 generally results in lower premiums than broader symbols, but it leaves gaps if a business drives vehicles not on the schedule.

When Symbol 31 Is Commonly Used

Businesses that operate a fixed fleet of vehicles and want to control premium costs often choose Symbol 31. It is also used when an insured wants to ensure that only certain high-value or specialized autos receive coverage under specific limits. Work trucks, delivery vans, and executive vehicles that are clearly identified in the policy declarations are typical candidates.

What Symbol 31 Covers and Excludes

With Symbol 31, coverage applies only to the autos listed in the policy. Newly acquired autos are not automatically covered unless the policy includes a separate provision for acquired autos or the vehicle is added to the schedule. Non-owned autos and autos used by employees for business purposes may also be excluded unless other symbols or endorsements apply to those coverage parts.

Why Symbol 31 Matters for Your Policy

Choosing Symbol 31 affects both cost and risk. It can reduce premium expenses by narrowing the insured fleet, but it requires careful record-keeping. If a business adds a vehicle and forgets to update the declarations, a claim could be denied. Understanding Symbol 31 helps you match coverage limits to the actual autos your business operates and avoid surprises at claim time.
