MILWAUKEE (WTAQ) - It will be against the law for Wisconsin’s youngest drivers to use their cell phones behind the wheel.

Governor Scott Walker signed a bill in Milwaukee Thursday that prohibits drivers with instruction permits and probationary licenses from using wireless devices.

The Assembly passed the bill unanimously last month, and the Senate gave it overwhelming approval earlier this month.

Teen drivers who violate the cell phone ban would be fined $20 to $40 for their first ticket. Repeat offenders will be fined $50 to $100.
