A new Kansas law takes effect tomorrow aimed at improving safety in active construction and school zones across the state.

Under Senate Bill 366, drivers may not use a handheld mobile device while traveling through an active construction zone where workers are present and warning signs are posted, or in an active school zone when reduced speed limits are in effect. Hands-free device use is still allowed. The Kansas Department of Transportation says officers will issue warning citations for violations through June 30, 2027, but beginning July 1, 2027, drivers who violate the law can receive a $60 traffic citation.

The new law also allows construction and maintenance vehicles to display green warning lights in addition to amber and white lights. Stationary trailers in construction zones may also use blue lights between sunset and sunrise when workers are present.
