DOT Mobile On-Site Testing

Mobile Drug Testing

Mobile drug testing and onsite drug testing both describe where the collection takes place, not how quickly results are produced.

The employee does not travel to a clinic. Simply put, mobile and onsite testing mean the collection happens at your location, not that the test is processed there or that instant results are provided. Industries we test onsite for are Logistics, Municipalities, and construction to name a few.

Trucking & Transportation

Mobile DOT Drug & Alcohol Testing for Fleets in Los Angeles

For trucking and transportation companies, compliance isn’t optional—it’s federally mandated under the Federal Motor Carrier Safety Administration (FMCSA). Missed testing windows, clinic delays, and paperwork errors can expose your company to fines, audits, and liability.

Crossroads provides mobile onsite DOT drug and alcohol testing directly at your terminal, yard, or dispatch facility.

Why Trucking Companies Choose Mobile Onsite Testing

Meet Post-Accident Timelines

DOT regulations require strict testing windows after certain accidents. Mobile response improves your ability to comply quickly—especially during nights and weekends.

Reduce Driver Downtime

Instead of sending drivers across town to a clinic, testing happens onsite—keeping routes, deliveries, and dispatch schedules intact.

Efficient Random Testing Events

We can complete multiple random selections in one visit, minimizing operational disruption.

Mobile DOT drug testing in Los Angeles keeps your fleet compliant—and your trucks on the road.

Construction & Infrastructure

Protect Safety-Sensitive Work Environments

One impaired worker can put an entire crew, and your contract, at risk.

Crossroads delivers mobile onsite drug and alcohol testing directly to construction jobsites, laydown yards, and project offices.

Why Onsite Testing Is Critical in Construction

No Lost Crew Time

Sending multiple workers to a clinic can shut down a crew. Onsite testing keeps the team available and the project on schedule.

Rapid Post-Incident Testing

In the event of an accident or injury, fast onsite response supports both safety protocol and documentation requirements.

Pre-Project & Contractor Screening

Large public and private projects often require proof of a compliant drug testing program before work begins.

We work with general contractors, subcontractors, and project managers to coordinate testing smoothly and professionally.

Ideal For:

Heavy civil contractors
Highway and bridge builders
Concrete and paving crews
Electrical and signal contractors
Equipment operators and skilled trades

Mobile jobsite drug testing in Los Angeles protects your workforce, your contract, and your reputation.

DOT-regulated drivers, safety-sensitive field crews, and administrative personnel. Managing testing across departments can be complex.

Crossroads provides mobile onsite drug and alcohol testing for municipal agencies, utilities, and public works departments—bringing compliant services directly to city facilities.

Why Public Agencies Use Mobile Testing
