Commercial Auto Insurance in Maine

Businesses operating vehicles in Maine need commercial auto insurance tailored to business exposures. Commercial policies differ significantly from personal auto policies in coverage, rating, and endorsements.

Business Auto Policy (BAP)

Standard Commercial Auto Form

The Business Auto Coverage Form (CA 00 01) is the foundation of commercial auto insurance:

Policy Structure:

  • Section I: Covered Autos
  • Section II: Liability Coverage
  • Section III: Physical Damage Coverage
  • Section IV: Business Auto Conditions
  • Section V: Definitions

Coverage Symbol System

The BAP uses numbered symbols (1-10) to designate which vehicles are covered:

SymbolDescriptionVehicles Covered
1Any AutoAll autos (owned, hired, non-owned)
2Owned Autos OnlyOnly autos business owns
3Owned Private Passenger AutosOnly owned cars, pickups, vans under 10,000 lbs
4Owned Autos Other Than Private PassengerOwned trucks, buses, commercial vehicles
5Owned Autos Subject to No-FaultAutos in no-fault states (not applicable in Maine)
6Owned Autos Subject to Compulsory Uninsured MotoristsAutos where UM required (Maine qualifies)
7Specifically Described AutosOnly autos listed on schedule
8Hired Autos OnlyAutos rented/leased by business
9Non-Owned Autos OnlyEmployee-owned autos used for business
10Mobile Equipment Subject to Compulsory or Financial ResponsibilitySpecial mobile equipment

Exam Tip: Symbol 1 (Any Auto) provides the broadest coverage. Symbol 7 (Specifically Described Autos) provides the narrowest coverage—only listed vehicles.

Typical Symbol Usage

CoverageCommon Symbols
LiabilitySymbol 1 (Any Auto) - broadest protection
Physical DamageSymbol 7 (Specifically Described) - only scheduled vehicles
UM/UIMSymbol 6 (Owned Autos Subject to UM)
Med PaySymbol 1 or Symbol 7

Reasoning: Businesses want broad liability protection (Symbol 1) but only insure physical damage on specific owned vehicles (Symbol 7) to save premium.

Liability Coverage

Commercial Auto Liability in Maine

Minimum Maine Requirements for Commercial Autos:

  • Same as personal autos: 50/100/25
  • Many businesses carry much higher limits ($500,000, $1 million, etc.)
  • Umbrella policies provide additional liability protection

Covered Exposures

Commercial auto liability covers:

Non-Owned Auto Liability

When employees use personal vehicles for business:

Non-Owned Auto Liability (Symbol 9) covers:

  • Employee-owned vehicles used for business purposes
  • Business liable for employee negligence while on business
  • Protects business (not employee's personal auto policy)

Critical Coverage: Many businesses have significant exposure from employees using personal vehicles for business errands, client visits, etc.

Example: Employee drives personal car to pick up office supplies. Causes accident en route. Business could be liable. Symbol 9 non-owned auto liability protects the business.

Physical Damage Coverage
