Combination vehicles/doubles

I've never heard the ruling of needing a year.Of course I took my 1st CDL test back in '98.When I did, I took the doubles/triples, and Haz-mat all at the same time.What they mean by other combo, vehicle,can be any vehicle that has two parts or more. i.e. tractor and (one ) trailer is a combination vehicle.

 

Combination vehicle is any truck and trailer.

Could be a tractor pulling a semi trailer or a dump truck pulling a small flatbed with a backhoe on it.

Doubles and triples, as the names imply, are pulling more than one trailer.

There are more things to consider when dealing with doubles and triples so they require separate endosement from simple truck/trailer combination.

 

A truck and trailer is a power unit that also holds cargo and then pulls a trailer. The other is just as it sounds. You don't see hardly any truck and trailers in the east but out west they are used a lot in the gasoline business. In my state a combination vehicle is all of them, tractor with a semi trailer, or any combination.

 

Go ahead and get it but you will have to wait 6 months and take some additional training (from your employer) and do a driving test (from your employer) to drive the doubles/triples. It is called Long Combination Vehicle certification or LCV for short.

 

Combination vehicles for class a.

General knowledge would get you nothing. Maybe a straight truck with no air brakes but i think theres another test to take.

 

That is a company decision to have a minimum experience time for dbl/tri. There is no such "time experience" requirement to get the endorsement, and no drive test for the dbls/tri, just a written test at the DMV.

 

My dad did this without the COMBINATION to be able to drive a church bus. He only got the minimum required (CDL with Passengers) and could take the test in an old mini-van he had at the time since the bus did not have air brakes.

 

Each state is different. I have a passenger endorsement but it is for class C vehicles. Doubles/triples. I have that endorsement also. Fed Ex hires students and you drive as a team. Driving doubles and triples is a lot easier then you would think it is. And in the winter on ice and snow, they almost park themselves. Watch sometime at how many of them find the ditch all by themselves.

To pull a B truck with a trailer behind it you need a combination vehicle endorsement. If there are air brakes involved, you need an air brakes endorsement. The Class A CDL contains air brakes and combination vehicles. To actually pull doubles, you need to have part of your brain removed. One driver pulling two trailers means one driver is unemployed and the other nut is doing his job for free. That is of course my opinion. But it is correct.
