Multi-Car Insurance — Illinois

A Illinois multi-car policy covers every vehicle in your household on one policy at the state's 25/50/20 liability minimum, and combining them earns the multi-car discount. Each vehicle can carry its own coverage level — liability only or liability plus collision and comprehensive — while the whole policy shares the discount.

Multi-Car Liability Requirements in Illinois

Every vehicle on a Illinois multi-car policy must carry the state's 25/50/20 liability minimum: $25,000 bodily injury per person, $50,000 bodily injury per accident, and $20,000 property damage. Illinois also requires uninsured motorist coverage on every vehicle. The multi-car discount applies when all vehicles sit on the same policy and typically share a garaging address, but each vehicle can carry its own level of coverage beyond the liability floor.

$25,000/$50,000 minimum
Bodily Injury Liability
Every vehicle on your Illinois multi-car policy must carry at least $25,000 per person and $50,000 per accident in bodily injury liability. This is the legal floor — you can raise the limit on one vehicle without raising it on the others, and the multi-car discount still applies to the whole policy.
$20,000 minimum
Property Damage Liability
Illinois requires $20,000 property damage liability on every vehicle. If you own multiple vehicles, each must carry this minimum even if one sits unused most of the time. Carriers writing in Illinois — including Allstate, State Farm, Progressive, and Geico — apply the multi-car discount when all vehicles are titled to the same household and sit on one policy.
Required
Uninsured Motorist Coverage
Illinois mandates uninsured motorist coverage on every vehicle on your policy. With 15.2% of Illinois motorists uninsured as of 2023, this coverage protects you when another driver causes an accident and carries no insurance. The requirement applies to each vehicle on a multi-car policy, not just the primary vehicle.
Same policy required
Multi-Car Discount
The Illinois multi-car discount requires every vehicle on the same policy and typically the same garaging address. Among carriers writing in Illinois, the discount applies when vehicles are titled to household members on one policy — but how the cars are titled and whose name appears on the policy can change the discount amount. Adding a vehicle mid-term re-rates the entire policy rather than adding a flat amount.
Optional per vehicle
Collision and Comprehensive
Each vehicle on your Illinois multi-car policy can carry its own level of physical-damage coverage. You can insure one vehicle with liability only and another with full coverage — collision, comprehensive, and the liability minimum — and still earn the multi-car discount on the whole policy. Each vehicle that carries collision or comprehensive has its own deductible.

What Shapes Multi-Car Costs in Illinois

Multi-car cost in Illinois depends on the vehicles, the drivers, the coverage selected per vehicle, and the multi-car discount. Among carriers writing in Illinois — including Acceptance, Bristol West, Dairyland, Elephant, GAINSCO, Infinity, Kemper, Mercury General, National General, The General, and Root — the discount structure varies: some require every vehicle titled to the policyholder, others allow household members on different titles. Adding a vehicle mid-term re-rates the entire policy based on the new vehicle's profile and the household's driving history.

What Affects Your Rate

  • Each vehicle's year, make, model, and how it's used — daily commute versus occasional use — shapes the per-vehicle portion of the Illinois multi-car policy.
  • The multi-car discount in Illinois typically requires all vehicles on the same policy and the same garaging address; how the vehicles are titled changes which carriers give the full discount.
  • Every vehicle on a Illinois multi-car policy must carry the state's 25/50/20 liability minimum and uninsured motorist coverage, but each vehicle can carry its own level of collision and comprehensive.
  • Among carriers writing in Illinois, the multi-car discount structure varies: some require every vehicle titled to the policyholder, others allow household members on different titles.
  • Adding a vehicle mid-term re-rates the entire Illinois multi-car policy based on the new vehicle's profile and the household's driving history, not a flat addition.
  • Illinois's 15.2% uninsured motorist rate as of 2023 makes uninsured motorist coverage mandatory on every vehicle, which adds to the per-vehicle cost on a multi-car policy.
Two Vehicles, One Policy
25/50/20 min
The baseline multi-car structure: two vehicles on one Illinois policy, each carrying the state's 25/50/20 liability floor. The discount applies to the whole policy, and each vehicle can carry its own coverage level beyond the minimum.
Adding a Vehicle Mid-Term
Re-rates policy
When you add a vehicle to an existing Illinois multi-car policy, the carrier re-rates the whole policy rather than adding a flat amount. The new vehicle's year, make, model, and how it's used all factor into the revised rate.
Combining Two Households
Same address
When two households combine — marriage, moving in together — the multi-car discount applies when all vehicles sit on one Illinois policy at the same address. Each driver's history affects the combined rate, and each vehicle must carry the state's 25/50/20 minimum.
