Questions from employers in this region
Poplar Bluff is in the heart of the Missouri Ozarks — why is on-site testing essential here?
Butler County and the surrounding Ozarks region are among the most clinic-sparse areas in Missouri. Sending CDL log truck operators or BNSF railroad employees to the nearest major clinic is a 40–60 mile round trip that takes an employee off the road or off the railroad for half a work day. Our mobile collector comes to your facility, mill yard, or rail yard — eliminating travel time and keeping your workforce on the job.
Timber CDL operations in the Ozarks start before dawn — can you test before first load?
Yes. Timber log truck CDL employers are a core use case for mobile testing. We meet your drivers at the mill staging area or log yard before first departure — testing the crew before they hit Ozarks roads where no clinic exists for miles.
