That depends on what the weight rating of the vehicle is. You could be talking about something like an F350 with a flatbed body, a tandem axle straight truck, or a tractor-trailer.. all three have different licence requirements.
Vehicles under 26,000 lbs. Gross Vehicle Weight Rating typically do not require a CDL, except in certain instances of where the vehicle is either hauling hazardous materials which require the display of placards, or where the vehicle is a bus designed to transport more than 15 persons (including the driver). If it doesn't meet either of these criteria, the only other way it would require a CDL if it was a NY registered vehicle with a GVWR of more than 18,000 lbs. and operating in the state of New York. In all of those instances, it would require a Class C CDL - if it doesn't meet any of that criteria, it doesn't require a CDL.
If it's a single vehicle with a Gross Vehicle Weight Rating of more than 26,000 lbs, then a Class B CDL is required. Additionally, a trailer with a weight rating of up to (but not in excess of) 10,000 lbs. may be towed.
For combination vehicles with a Gross Combination Weight Rating in excess of 26,000 lbs, in which the vehicle in tow (usually a trailer) itself has a weight rating in excess of 10,000 lbs., then a Class A CDL is required.
To drive a cement truck legally, you need a class B CDL (Commercial Drivers License). At 18, you can apply for a class B CDL.
The length of the trailer and truck is immaterial. What matters are the weight ratings.Truck with a GVWR of 26,000 lbs. or less = no CDL requiredTruck with a GVWR of 26,001 lbs. or more = Class B CDL requiredIn either instance, you can pull a trailer with a GVWR or 10,000 lbs. or less without having to upgrade to a Class A CDL. However, if that trailer has a GVWR of 10,001 lbs. or more, and it brings the Gross Combined weight rating in excess of 26,000 lbs. - regardless the GVWR of the power unit - then a Class A CDL is required
Assuming you mean a tandem axle truck, that would be a Class B CDL with tanker endorsement.
No. It is not required for you to have a CDL drivers license to lease a Penske Truck. This type of rental is just as a car rental. You are required to have only a C class License.
Class 3 truck with a rollback body? No, it doesn't require a CDL.
Length does not determine whether or not a CDL is required.
The regulations for when a CDL is required has nothing to do with length.
Depends. You can drive up to a Class 6 truck (up to 26,000 lbs. GVWR) without a CDL. Class 7 or Class 8 trucks require a CDL.
Truck classification isn't concurrent with the license required to drive them. A single axle water truck could be a Class 5, 6, 7, or 8 truck, depending on the vehicle GVWR. A Class 7 or Class 8 truck would require a (minimum) Class B CDL.
Generally you will need a CDL license and a certificate of proficiency in driving a truck.
No. A CDL is required for Class 7 and 8 trucks, and is only required for Class 6 and below if they are either transporting quantities of hazardous materials which require placards to be displayed, or are commercial buses designed to transport more than 15 persons (including the driver).
If it's rated and registered for more than 26,000 lbs., and you have a Class B CDL, yes. If any of the criteria up top isn't met, no.
