Illinois Gov. J.B. Pritzker (D) has signed legislation that prohibits adult drivers and passengers from smoking in a vehicle if a minor is inside.

House Bill 2276 makes it illegal for drivers and passengers to smoke a “lighted cigarette, cigar, pipe, weed, plant, regulated narcotic” or other any other “combustible substance” inside a car if a person under the age of 18 is inside.

“A person shall not smoke in a motor vehicle, whether it is in motion or at rest, if a person under 18 years of age is in the vehicle, regardless of whether the vehicle's windows are open,” the legislation states.

The legislation, which passed the Illinois state House and Senate earlier this year, was signed on Friday and has taken immediate effect, according to the governor's website.

Violation of the law is a petty offense and is punishable by a fine of up to $100. The law states that second-time offenders can be fined up to $250.

However, the legislation adds that vehicles and those inside cannot be searched by law enforcement based solely on a violation or suspected violation of the law.
