CDL (Commercial Driver’s License)
A CDL is a license that allows you to legally operate commercial motor vehicles (CMVs) such as semi-trucks, buses, and other large or specialized vehicles.
- Required for vehicles over certain weight limits (26,001+ lbs GVWR)
- Allows you to drive without supervision
- Requires passing skills tests (pre-trip, backing, road test)
- Comes in different classes:
- Class A → Tractor-trailers (most semi trucks)
- Class B → Straight trucks, dump trucks, buses
- Class C → Smaller vehicles requiring endorsements (hazmat, passenger, etc.)
Think of it as your full professional license to drive commercial vehicles.
CLP (Commercial Learner’s Permit)
A CLP is a permit that allows you to practice driving a commercial vehicle on public roads while supervised by a qualified CDL holder.
- It is the first step toward getting a CDL
- You must have a licensed CDL driver in the passenger seat
- You are limited in what you can do (no solo driving, restrictions on passengers, etc.)
- Typically requires passing written knowledge tests
Think of it as the “learner’s permit” for semi-trucks.

Deadheading
Deadheading refers to operating a truck while pulling a trailer that is completely empty—no cargo inside—typically between loads.
Common situations where deadheading happens:
- Delivering a load, then driving empty to the next pickup
- Repositioning equipment to a higher-demand area
- Returning a trailer to a yard or terminal
- Carrier routing you to another shipper
