Bike Law FAQs
Question: What traffic laws apply to bicyclists?
When ridden on any roadway a bicycle rider has all of the rights and
responsibilities of any vehicle (RCW 46.61.755). Unless bicycles are
specifically excepted, all traffic laws and rules apply to bicycles. Bicyclists who
violate traffic laws are subject to a citation.

Question: Should bicyclists ride with the flow of traffic or facing traffic?
Bicyclists should always ride with the flow of traffic (RCW 46.61.100).
The law requires this. Riding with the flow of traffic greatly increases safety by
making bicycles visible and predictable to other drivers. Riding against traffic is
leading cause of bicycle accidents.

Question: What position in the lane should a bicyclist use?
1) Bicyclists traveling at the speed of traffic may use the middle of the lane.
2) A bicyclist traveling at a speed less than the normal flow of traffic should
ride as near to the right side of the right through lane as is safe except when a)
preparing to turn b) when passing another bicycle or vehicle or c) on a one-
way street, where it is legal to ride on the left (RCW 46.61.770).
3) Bicyclists should ride in the middle of the right through lane when that lane
is too narrow to permit side-by-side sharing with motor vehicles, and when
hazards (such as drain grates or a rough edge) prevent riding on the shoulder
or along the edge of the lane.
4) Bicyclists may ride on the road shoulder, but this is required only on limited-
access highways, such as freeways.

Question: May bicyclists ride side-by-side?
Yes. State law allows bicyclists to ride two abreast (RCW 46.61.770).

Question: What equipment is required on bicycles used at night?
A white front light and a red rear reflector are required (RCW
46.61.780). In addition, a red rear lamp and/or flashing amber light is allowed.
Use of reflectors alone does not satisfy state requirements.

Question: Where is bicycling not allowed?
1) On sidewalks within business districts (RCW 46.90.555) if adopted by local
government.
2) On designated sections of our state's limited-access highway system.

Question: Are bicyclists required to use a bikepath adjacent to a roadway?
No. A bicyclist may choose either a path or the roadway. Some paths
are not well suited to cyclists' needs, particularly fast riders or when crowded
with other users.
Back to Bike Law FAQs
Question: Are children required to observe bicycle traffic laws?
Yes. Bicyclists of all ages are required to follow the same traffic laws
and may by cited for violations. In addition, a parent or guardian shall not
knowingly permit bicycle traffic violations by their ward (RCW 46.61.700).
