From a Washington State Patrol press release:

The Impaired Driving Section of the Washington State Patrol (WSP) is deploying the Mobile Impaired Driving Unit (MIDU) from Nov. 22 to 25. This deployment is in support of the DUI emphasis kicking off the holiday season.

The MIDU is a self-contained 36-foot motorhome that has been retrofitted as a mobile DUI processing center and incident command post. The MIDU is equipped with three breath testing instruments, two temporary holding cells, three computer work stations, an incident command computer terminal, a dispatcher console with wireless access to WSP dispatch centers and a microwave downlink tower for real time broadcasts from WSP aircraft. This is a full service police station on wheels!

Additional troopers and other law enforcement agencies will be out on the roads in an effort to keep them as safe as possible. Do not drive impaired and be safe and enjoy this holiday season.
