Snow And Traction Restrictions Have Arrived

The Washington State Patrol Commercial Vehicle Division wants drivers to protect themselves and their passengers while traveling over our States Mountain passes this year. It takes only one unprepared or careless driver to slow or stop traffic.

After last year’s unprecedented three pass closures and the increasing amount of cross-state commercial vehicle traffic, the chain law requirements must be strictly adhered to in hopes of mitigating the amount of economic impact but, more importantly, the safety aspects associated with passenger and commercial vehicle-related incidents caused by drivers who are either ill-prepared or blatantly choose to ignore the chain law.

Strict enforcement of the chain carry requirement will be conducted. Commercial Truck drivers in violation can be cited $500.00 and NOT allowed to proceed into the mountain pass zone until in compliance. This included those drivers that had the correct number of chains but failed to have the proper number of chains (2) to meet the spare chain requirement.

Commercial Vehicle Troopers and Commercial Vehicle Officers will also be proactively doing “ Sleeper” enforcement on those CMV drivers choosing to sleep in the designated chain areas either to wait out the storm (so they do not have to chain) or who wish to use it as a rest stop instead of finding a safe location off the roadway.
