Travelers should prepare for delays and stay alert on roadways

OLYMPIA – Drivers should plan for extra travel time Saturday, July 13, and Sunday, July 14, and everyday riders will find they have a lot of company on two wheels as 8,000 bicyclists ride western Washington’s state highways and local roads for the 2019 Kaiser Permanente Seattle to Portland Bicycle Classic.

The Washington State Department of Transportation asks motorists to observe the rules of the road for safe driving around people on bikes and to prepare for travel delays during the popular recreational ride. As state driving laws periodically change, drivers may want to review the state driver guide and the driving among bicyclists section.

Bicyclists should also be aware of their responsibility to follow Washington’s bicyclist rules of the road. The Cascade Bicycle Club distributes a free pocket guide about state bike laws with support from the Share the Road license plate sales.
