The Illinois Senate has approved legislation to allow school districts to use cameras to catch people who don't stop for buses picking up or dropping off kids.
The owner of a vehicle captured by the cameras could be fined $150 for a first offense and $500 for each subsequent offense.
The bus must have its stop sign extended and lights flashing. It must also be clear that students are either getting on or off of the bus.
Lawmakers voted 36-12 in favor of the bill, which now moves to the House.
Sen. Antonio Munoz is a Chicago Democrat and the bill's sponsor. He says it will deter people from passing buses and endangering kids.
Opponents say it's unconstitutional because people who receive tickets can't challenge them in court.
