High-Yield Washington Traffic Laws & Penalties

Washington state statutes contain specific legal thresholds that appear frequently on knowledge exams:

• THC & Cannabis Per Se Limit (RCW 46.61.502): Drivers age 21 and older are guilty of driving under the influence if their blood contains 5.00 nanograms or more of active Delta-9 THC per milliliter. For drivers under 21, Washington enforces strict Zero Tolerance (0.00 ng/mL).
• Distracted Driving (RCW 46.61.672): Holding a personal electronic device in your hand while operating a motor vehicle (including while stopped at red lights or stop signs) is an enforceable primary traffic infraction.
