Sammamish police will be continuing special emphasis patrols through Sunday to stop motorists from speeding, as part of a campaign sponsored by the Washington Traffic Safety Commission.
The state safety group reported that driving faster than the speed limit contributes to a third of all fatal automobile crashes in Washington.
On July 21, three area teenagers - including a 16-year-old boy from Sammamish - were taken to area hospitals after the driver lost control of a Subaru Impreza and crashed into a fence and tree at Southeast 25th Way and Beaver Lake Way Southeast.
Investigators with the King County Sheriff's Office attribute high speed to the incident.
Sammamish police announced its participation in the anti-speeding campaign - known as "Slow Down or Pay Up" - on its Facebook page.
