Olathe sits on I-35 south of Kansas City, KS in Johnson County - consistently one of the wealthiest and fastest-growing counties in the Midwest. Garmin International's global headquarters is in Olathe, anchoring a technology and GPS manufacturing employer base with a large skilled workforce. The I-35 South corridor through Olathe connects Kansas City metro to Wichita, routing motor carriers, LTL distributors, and logistics operators through Johnson County daily. Distribution centers and regional fulfillment operations have clustered along the I-35 and I-435 interchanges in Olathe to serve the broader Kansas City metro. Commercial construction has been relentless in Johnson County, with one of the most active building permit markets in the region. The Olathe Medical Center and nearby healthcare campuses add employer testing demand for the county's large healthcare workforce. OnSite Employer Testing dispatches mobile collectors to Olathe fleet yards, distribution centers, manufacturing facilities, and employer sites throughout Johnson County.

Applicable Regulations - Olathe, KS
DOT-regulated employers in Olathe are primarily subject to 49 CFR Part 382 (FMCSA - motor carriers on I-35 South and I-435) and 49 CFR Part 40. Technology and defense-adjacent manufacturers holding federal contracts may have Drug-Free Workplace Act obligations (41 U.S.C. Section 8102). Kansas has no recreational or medical cannabis law - the state is zero-tolerance for cannabis. Olathe and Johnson County border the Kansas City, MO metro where Missouri recreational cannabis is legal - Missouri law has no effect on Kansas employer programs. A positive THC result under a Kansas employer's written policy can be acted upon regardless of Missouri cannabis law. Program design remains the employer's responsibility.

Questions from employers in this region
We operate a distribution center on I-35 in Olathe with CDL drivers and non-DOT warehouse workers - can you handle both programs in one dispatch?
Yes. At booking, specify which employees are FMCSA-regulated CDL drivers and which are non-DOT warehouse staff. Our collector arrives with the correct chain-of-custody documentation for each program and processes each population separately. Provide your dock schedule and shift windows so we can minimize operational disruption.
We are a tech manufacturer in Olathe - can you come to our facility for pre-employment collections rather than sending candidates to a clinic?
Yes. Non-DOT pre-employment testing is a core service. We dispatch to your Olathe facility for pre-employment collections under your company's written policy. Provide your address, candidate count, and preferred window at booking.
Our Olathe employees live in Missouri where cannabis is recreational - does that affect our Kansas drug policy?
No. Missouri cannabis law does not apply to your Kansas workplace. Your written drug and alcohol policy governs all employees at your Olathe facility regardless of their state of residence. A positive THC result can be acted upon under your Kansas policy without Missouri cannabis law complications. Policy enforcement decisions are the employer's responsibility.
