Charges are pending against a Port Angeles woman who allegedly struck a fire district medical vehicle with her car while driving under the influence on Dec. 5.

Washington State Patrol confirmed that three firefighters with Clallam County Fire District 3 were driving westbound on U.S. Highway 101 near Lewis Road across from Blue Mountain Road at 1:30 p.m. when Charlotte Marsh struck the ambulance in her Nissan Ultima.

Fire District 3 Assistant Chief Tony Hudson said the medical unit was traveling to an aid call without lights and sirens on when the collision occurred.

Marsh received minor injuries and was transported by another fire district medical unit to Olympic Memorial Hospital and later released, Hudson said.

The medical vehicle sustained significant damage but wasn’t totaled, Hudson said.

Its passengers — Matt Newell, firefighter/paramedic, Mark Mullvain, firefighter/paramedic, and Jim Whitaker, firefighter/EMT — were not injured.

Washington State Patrol Trooper Russ Winger said the extent of damage to Marsh’s car was not known.
