This endorsement is required if the driver will pull two or three trailers. To receive this endorsement, applicants must pass a test. The test consists of 20 multiple choice questions. To pass, the applicant must answer at least 16 questions correctly. Each question has three possible answer choices. Test questions come from the Virginia Commercial Driver License Manual. Questions come from chapters covering: Driving Safely, Air Brakes (if applicable), Combination Vehicles and Doubles and Triples. The Double/Triple endorsement can be used with the Class A CDL.

When using a fire extinguisher, you should stand as far away from the fire as possible. Aim the extinguisher at the base of the fire, not at the flames. If you are not sure which kind of extinguisher should be used on a fire, particularly a hazardous materials fire, you should wait for the firefighters to arrive and allow them to extinguish it.

In Virginia, if you are caught operating a commercial vehicle with double or triple trailers without the proper endorsement on your CDL, you could face fines, license suspension or revocation, and other penalties. 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.

1. Proper Coupling and Uncoupling: Double/triple trailers must be coupled and uncoupled in a specific way to ensure that they are safe and secure. Drivers must be trained on the proper procedures for coupling and uncoupling.
2. Maneuvering: Because double/triple trailers are longer and heavier than single trailers, they require more space to maneuver. Drivers must be aware of their surroundings and make wider turns to avoid hitting other vehicles or objects.
3. Braking: Double/triple trailers require more braking distance than single trailers, especially when fully loaded. Drivers must allow enough space to stop safely and avoid emergency braking whenever possible.
4. Speed Limits: In some states, there are lower speed limits for double/triple trailers than for single trailers. Drivers must be aware of these speed limits and drive accordingly.
5. Inspection: Double/triple trailers must be inspected regularly to ensure that they are in good condition and safe to operate. Drivers should inspect their vehicle before each trip and report any issues to their employer.
