Steer/Tillerman Questions
-
It depends on where you are positioned and how the vehicle is being operated.
According to federal guidance (49 CFR Part 383, Question 24):
If you are physically located on the trailer and controlling a steerable rear axle while the vehicle is moving at highway speeds, you are considered to be operating a commercial motor vehicle (CMV) and must hold a valid CDL.
If you are physically located on the trailer but only steering at slow speeds, such as while maneuvering in a yard, job site, or staging area, you are not considered a CMV operator for CDL purposes and would not need a CDL.
If you are walking beside the vehicle or riding in an escort car while controlling the steerable rear axle at slow speeds, you also do not need a CDL, since you are not operating the CMV in the sense defined by federal law.
In summary:
On the trailer at highway speeds → CDL required
On the trailer at slow speeds → CDL not required
Walking or escorting at slow speeds → CDL not required
Keep in mind that some states may have additional CDL requirements or interpret these rules differently.
Always verify with your state’s Department of Transportation or licensing agency to ensure full compliance with local regulations.
