OUR SPECIALTY

RETURN-TO-DUTY TESTING

A DOT violation doesn't have to end a career. When a driver fails a test, the clock starts ticking — delays cost money, disrupt operations, and keep drivers off the road.

The 5-Step DOT Return-to-Duty Process:

  1. Failed DOT test documented

  2. SAP evaluation completed

  3. Education & treatment program

  4. SAP follow-up clearance report

  5. Return-to-Duty specimen collection — this is where we come in

"We guide drivers and employers through every step — from SAP referral to follow-up testing — so they can get back on the road with full compliance. It's the work we know better than anyone."

— TIFFANY, FOUNDER & LEAD COLLECTOR
