DOT-Regulated & Non-Regulated Employer Programs

DOT-regulated businesses, including trucking, transit, and other transportation operators in the King County area, are required to conduct pre-employment, random, post-accident, return-to-duty, and follow-up testing under 49 CFR Part 40. We support those programs with compliant collection and documentation. For non-regulated employers, we can assist with policy creation, ongoing program management, and the testing those programs require.

On-site mobile testing is also available when bringing staff to a facility isn’t practical.

Washington Marijuana Law & Drug Testing

Washington State permits adult recreational and medical marijuana use. Under Washington SB 5123, which took effect January 1, 2024, most employers are prohibited from making initial hiring decisions based on a pre-employment drug test that screens for non-psychoactive cannabis metabolites. Exemptions apply to certain roles, including safety-sensitive positions, law enforcement, fire departments, and positions subject to federal drug testing requirements. Post-accident and reasonable suspicion testing are not affected by this law. Employers should consult their legal counsel when developing or updating their drug testing policies. Our role is to collect and report results accurately and confidentially, not to advise on policy or legal compliance.
