AUSTIN, Texas (AP) — Some Texas troopers will give up patrol cars and instead ride school buses in a child safety effort.

The Texas Department of Public Safety says the plan is part of National School Bus Safety Week, which began Monday and runs through Friday.

It's illegal in Texas to pass any school bus that is stopped and operating a visual signal — either flashing red lights or a stop sign. Troopers will be watching for drivers who violate the law, which could lead to fines of up to $1,250.

A DPS statement says troopers in parts of Texas will be riding on or following school buses to catch violators.

Texas troopers, during 2015 and so far in 2016, have issued nearly 1,100 tickets for illegally passing a stopped school bus.
