Sharing the RoadStandalone practice
You wait to turn left at an intersection. An oncoming rider on a Class 3 electric-assisted bicycle is coming toward you in the bike lane. What should you keep in mind?
Correct answer: Its motor can assist up to 28 mph, so it may arrive sooner than you think
Why
Washington law sorts e-bikes into three classes: Classes 1 and 2 stop the motor help at 20 mph, and Class 3 stops at 28 mph and has a speedometer. Since 11 June 2026, a bike that can go faster than 20 mph on the motor alone is not an e-bike. Drivers can misjudge how fast a small vehicle approaches, so look twice before you turn.
