Driving east down Grand Avenue while holding and talking on your cell phone is fine, but pass that invisible Gurnee line on Lawrence Avenue to Waukegan, and you just may receive a fine.

That’s because the City of Waukegan has a cell phone ordinance banning the use of mobile phones while driving a motor vehicle, unless used through a hands-free device, when calling 911 or other emergency numbers and while the car is in a stationary and parked position.

Waukegan police officers enforce this ordinance with citations and a $50 fine. The fine can be $200, if the driver talking on the cell phone is involved in an accident.
