Multi-Car Liability Requirements in Maryland
Maryland requires every vehicle on a multi-car policy to carry $30,000 bodily injury per person, $60,000 bodily injury per accident, $15,000 property damage, plus Personal Injury Protection and uninsured motorist coverage. The state uses an at-fault system, so the driver responsible for a crash pays for the other party's damages through their liability coverage. The multi-car discount applies when all vehicles sit on the same policy and typically requires a shared garaging address.

Multi-car policy costs in Maryland depend on the number of vehicles, the drivers assigned to each vehicle, the coverage level selected per vehicle, and the multi-car discount. Each vehicle on the policy can carry liability only or full coverage with collision and comprehensive, and the discount applies to the total premium when all vehicles sit on one policy.
What Affects Your Rate
- Maryland's $30,000/$60,000/$15,000 liability minimum plus required PIP and uninsured motorist coverage sets the floor each vehicle on a multi-car policy must carry.
- The multi-car discount typically requires all vehicles to sit on the same policy and share a garaging address—carriers writing in Maryland including Geico, Progressive, State Farm, and Allstate apply this requirement.
- Each vehicle's year, make, model, and assigned driver shape the per-vehicle premium—a 2015 sedan assigned to a 40-year-old driver costs less than a 2023 SUV assigned to a 19-year-old.
- Maryland's 16.9% uninsured motorist rate (2023) makes uninsured motorist coverage mandatory on every vehicle, adding to the per-vehicle cost.
- Adding collision and comprehensive to one vehicle on the policy raises that vehicle's premium while leaving the others at liability-only cost—the multi-car discount applies to the total.
- Maryland's at-fault system means the driver responsible for a crash pays through their liability coverage, so raising liability limits above the state minimum reduces out-of-pocket risk in a serious crash.

Multi-Car Policy Structure
A multi-car policy puts two or more owned vehicles on a single Maryland policy, each carrying at least the state's required liability, PIP, and uninsured motorist coverage. Each vehicle can carry its own coverage level—liability only or full coverage with collision and comprehensive—while the entire policy earns the multi-car discount.
Liability Coverage Per Vehicle
Every vehicle on your Maryland multi-car policy must carry the state's $30,000/$60,000/$15,000 liability minimum plus required PIP and uninsured motorist coverage. Each vehicle on the policy carries its own liability limit—you can raise one vehicle's limits while leaving another at the state minimum.
Full Coverage on Select Vehicles
Full coverage adds collision and comprehensive to a vehicle's required liability, PIP, and uninsured motorist coverage. On a Maryland multi-car policy, you can add full coverage to one vehicle—typically the newest or most valuable—while leaving others at liability only, and the multi-car discount applies to the total premium.
Uninsured Motorist Coverage
Maryland requires uninsured motorist coverage on every vehicle on a multi-car policy. This coverage protects you when an at-fault driver has no insurance or insufficient coverage to pay for your injuries, and it applies per vehicle on the policy.
Adding a Vehicle Mid-Term
Adding a vehicle to your Maryland multi-car policy mid-term recalculates the entire policy premium rather than adding a flat amount. The new vehicle's premium is prorated from the add date to the policy renewal, and the multi-car discount adjusts with the new vehicle count.
Combining Household Policies
Combining two separate policies into one multi-car policy after marriage or a household member moving in typically requires all vehicles to share the same garaging address to earn the multi-car discount. Each vehicle retains its own coverage level—one can carry full coverage while another carries liability only.
