Carrying Illinois state minimum liability limits of 20/40/15 -- $20,000 per person and $40,000 per accident for bodily injury and $15,000 for property damage -- doesn't give you much protection if you own a home or have savings. Once your limits are reached, you can be sued in court for remaining accident costs.
Most experts say 100/300/50 offers an adequate shield for a typical family.
Illinois also requires that you buy uninsured motorist bodily injury coverage. Underinsured motorist (UIM) coverage can be rejected in most cases. Talk to your insurer first.
If you don't have collision coverage on your vehicle, then Illinois car insurance providers are required to offer you uninsured motorist property damage (UMPD) with a maximum limit of $15,000 (subject to a $250 deductible), but you can reject it.
If you want your vehicle covered for any type of collision, just not those with an uninsured motorist, collision coverage is a much better choice than UMPD. And to have your vehicle covered for fire, theft, vandalism or damages from natural disasters, then you will also want to carry comprehensive coverage.
Comparative negligence: Illinois has adopted a modified comparative negligence stance for the recovery of auto accident damages. This means that you may recover damages only if you are less than 50 percent at fault for the damages or injuries. And the amount you recover may be reduced in proportion to the degree that you are at fault. So, if you're found to be 20 percent at fault, you can claim against the other party, but the third-party insurer may only pay 80 percent of your damages.
Reasons for cancellation: During the first 60 days of a new policy your Illinois car insurance company may cancel for almost any reason. After 60 days, there are still many reasons that the state allows your insurer to cancel or non-renew your policy. Read the full list on the Illinois Department of Insurance's website.
Points system: Illinois has a unique way in which it applies points to your driving record. While the state does have a point schedule, the Driver Services Department goes by the number of moving violations you have been convicted of. Once you reach a certain point, the Department can assign you points to determine how long your license suspension will be. See "How long do points stay on your license in Illinois?" for more information.
