Truck Roadside Assistance Service in Tyler, TX

What Should I Do if My Truck Breaks Down?

If your truck breaks down on the road, follow these steps before help arrives:

1. Signal immediately - activate your hazard lights as soon as you notice a problem, even before you've pulled over
2. Get off the road - pull as far onto the shoulder or away from traffic as possible; a breakdown lane or exit ramp is safer than the travel lane
3. Make yourself visible - set out reflective triangles or flares behind the truck at 10, 100, and 300 feet; put on a high-visibility vest if you have one
4. Chock the wheels - if you're on any grade at all, chock the drives and trailer wheels before getting out
5. Stay away from traffic - stay in the cab or well off the road on the passenger side, away from the travel lane
6. Call Hex 6 - call (903) 343-9527 with your location, truck details, and a description of what happened. The more information you can give us, the better prepared our technician will be when they arrive
7. Don't attempt unsafe repairs - brake failures, steering issues, and fuel leaks are not roadside repairs. If your truck has a safety-critical failure, wait for professional help

Roadside vs. Mobile Truck Repair

Both services dispatch a Hex 6 mechanic to your location - the difference is the situation:

Roadside Assistance is for emergencies. Your truck is broken down on a highway, road, or shoulder and you need help now. The priority is getting you safe, diagnosing the problem, and either repairing it on-site or coordinating transport to our shop.

Mobile Truck Repair covers both emergency and planned on-site service. If your truck is at a yard, terminal, or job site and needs service without coming into the shop - that's mobile truck repair. It can be scheduled in advance.

Both operate within the same 40-mile radius. If you're not sure which applies to your situation, just call - we'll figure it out together.

Fleet Operators - Priority Roadside Dispatch

For trucking companies and fleet operators, a single breakdown can cascade into scheduling and delivery failures across the whole operation. Hex 6's Fleet Advantage program includes priority dispatch for roadside calls - Fleet Advantage members jump the line when a truck goes down.

Combined with scheduled preventive maintenance to reduce breakdown frequency, Fleet Advantage is built for operations that can't afford unplanned downtime.
