Additionally, your employer could also face fines and other penalties for allowing an unqualified driver to operate a commercial vehicle.
It is important to obtain the proper endorsement on your CDL before operating double or triple trailers to ensure that you are in compliance with FMCSA regulations and Virginia state law. This will help you avoid legal issues and ensure that you are qualified to safely operate these vehicles.
To take the written exam, you will need to visit a Virginia Department of Motor Vehicles (DMV) office and provide your current CDL license, proof of identity, and payment for the endorsement fee. You will then need to pass the written exam with a score of at least 80%.
After passing the written exam, you will need to schedule and pass the Doubles/Triples skills test. This test will evaluate your ability to safely operate a commercial vehicle with double or triple trailers. Once you pass the skills test, the Doubles/Triples endorsement will be added to your existing CDL license.
