What You Need to Know Before Taking the CDL Driving Test

It is much harder to obtain a commercial driver’s license than it is to walk into a DMV and pass the test for a standard driver’s license.

By law, each state is required to meet the same minimum standards for operating a commercial vehicle. Drivers must have a CPL to operate the following:

  • A vehicle with a gross vehicle weight rating that is over 26,000 pounds.
  • A trailer and towing unit combination that exceeds 26,000 pounds GVWR, with the trailer over 10,000 pounds GVWR.
  • A vehicle that transports 16 or more passengers, including the driver.
  • A vehicle of any size which transports hazardous materials that require a hazmat placard.

Getting behind the wheel of a commercial vehicle requires a higher level of knowledge, skill, physical ability, and experience than it does to drive a car. If you want to drive a commercial vehicle such as a big-rig or a school bus, you must pass a CDL driving test and:

  • Be 18 years of age
  • Have a clean driving record
  • Have no felony conviction
  • Pass a physical exam every two years
  • Pass a vision test

  • Inside and outside truck inspections
  • Straight line backing
  • 90 degree alley docking
  • Stopline
