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. Each question has four answer choices. To pass, the applicant must answer at least 16 questions correctly. Test questions come from the New York State Commercial Motor Vehicle Drivers Handbook. 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.
1. When driving in heavy traffic, you should:
Areas with heavy traffic, road construction, large numbers of pedestrians, or severe weather demand extra attention from a driver. The driver should avoid all possible distractions while in such areas, including cell phone use.
2. You should always be able to stop within:
You should always make sure that your vehicle will be able to stop within the area of the road that you are able to see. This means that you must slow down whenever conditions reduce visibility.
3. If a vehicle has a vehicle inspection report, the driver:
For the first step of a vehicle inspection, you should review the last inspection report on your vehicle, if there is one. The carrier should have repaired any problems noted on the report.
4. When backing, it is best to:
If you must drive in reverse, you should back up slowly and use the mirrors on both sides of your vehicle. Use a helper to monitor your blind spots whenever possible. You and the helper should agree on a signal for "stop."
5. Why are roads especially slippery right after it begins to rain?
In rainy weather, roads are often at their most slippery when the rain first begins to fall. Fresh rainwater mixes with oil and grease on the road to form a slick film. As the rain continues, this mixture will eventually wash away.
6. To make it as safe as possible to leave a stop, you should park:
Backing can be dangerous, so avoid doing it whenever you can. If possible, park in such a way that allows you to pull forward to exit your parking space.
7. One way to overcome the challenges of blind spots is to:
You should make frequent mirror checks to monitor the traffic around you. This should help you notice if surrounding vehicles begin to move into your blind spots.
