We are grateful to have an amazing group of technicians here at GTG. In the shop or on the road, their hard work and expertise ensure our customers get back on the road and their business moving forward.
To all of our service team, thank you for all you do! We truly couldn't do it without you!

International Roadcheck Week is coming up on May 12–14. Is your fleet ready?

This year’s focus is on ELD tampering/falsification and cargo securement, along with full inspections of critical components like brakes, driveline/driveshaft, driver seats, fuel and exhaust systems, lighting, tires, wheels, rims, and more.
✅ Stay ahead of inspections and limit downtime
✅ Keep your drivers safe and compliant
Bring your truck into any GTG service shop for a DOT inspection — or let our mobile service team come to you and inspect your entire fleet. If repairs are identified and approved, we’ll waive the inspection cost.
Our goal is simple — keep your business on the road.
