Troopers from the Washington State Patrol are doing an emphasis patrol this week on carpool violators.

The five-day emphasis focuses on freeways between north Pierce County and south Snohomish County. It includes all of King County.

In 2017, Washington State troopers contacted 11,330 drivers for high-occupancy vehicle (HOV) violations – an increase of more than 200 over the previous year. Of those, 428 were repeat offenders.
