Mobile DOT testing services
OnCall DOT brings convenient, professional mobile drug testing to employers, drivers, and worksites—so compliance can happen without disrupting the day.
Built for the road
A straightforward mobile testing experience from request to completion.
The OnCall standard
We are building OnCall DOT around the practical things that matter when testing is time-sensitive: clear next steps, respectful service, and a mobile process designed around your schedule.
Know what to expect before the appointment and what happens next after testing.
A focused, respectful experience for every driver, candidate, and team member.
Bring the appointment closer to the people and places that need it.
How we help
