IL SB3493

Amends Section 12-603.1 of the Illinois Vehicle Code to make failure to wear a seat safety belt considered evidence of negligence in civil cases.

Removes language that previously stated seat belt non-compliance "shall not limit the liability of an insurer, and shall not diminish any recovery for damages" from motor vehicle incidents.

Maintains existing exceptions to seat belt requirements including drivers operating in reverse, vehicles pre-1965, motorcycles, mopeds, authorized emergency vehicles, and back seat taxi passengers.

Preserves medical exemptions allowing drivers or passengers with physician statements or official certificates proving inability to wear seat belts to be exempt from the requirement.

Keeps violation as a petty offense with a maximum fine of $25 and prohibits law enforcement from searching vehicles or persons solely for seat belt violations.
