- The multi-car discount in Illinois requires every vehicle on the same policy, and most carriers require the vehicles to share a garaging address.

- Illinois had 8,509,418 licensed drivers and 10,334,435 registered vehicles in 2022, and the state's 15.2% uninsured motorist rate shapes uninsured motorist premium for each vehicle on a multi-car policy.
- Carriers writing in Illinois structure the multi-car discount differently — some apply it per vehicle, others reduce the base rate for the entire policy, so comparing carriers matters.
- Adding a vehicle mid-term re-rates the entire Illinois policy rather than adding a flat amount, and the multi-car discount adjusts immediately.
