Illinois Commercial Auto policies are not treated exactly the same as ordinary personal auto policies for every statutory consumer-protection provision.
Illinois law nevertheless requires insurance policies subject to applicable provisions of the Illinois Insurance Code to contain cancellation provisions.
For certain policies subject to 215 ILCS 5/143.16, current Illinois law generally requires:
At least 30 days' notice
during the first 60 days of coverage
At least 60 days' notice
after coverage has been effective 61 days or more
At least 10 days' notice
when cancellation is for nonpayment of premium.
The specific statutory category and policy terms matter.
