Well, according to the FMCSA, you're still bound by the 11/14/70 hour Hours of Service regulations. However, if your company gets audited, and there's no logbooks to show, they look at how many hours their employees worked weekly. But even that's a bit difficult for the DOT to go on, since, if a company claims you didn't drive a CMV once you reached the 70 hour mark, how is the DOT going to prove otherwise? I've worked the oilfields and I've hauled for a road construction outfit (albeit with a Class A, but the regs are the same), and have worked shifts of up to 30 hours. There's that which they can do, and that which they can get away with.
They can work up to 70 hours in a seven day period.
The same times you'd use it with any class of CDL anywhere else. If you operate more than 150 road miles/100 air miles from your home base, and if you work for an interstate company, any time your total work hours exceed 12 hours.
Not sure what you mean, exactly. Class A is considered the "higher" classification, yes. If you have a Class A CDL, you can operate vehicles requiring that class of licence or any class below that. You could operate a vehicle requiring a Class B CDL, for example, but a driver with a Class B CDL wouldn't be permitted to operate a combination requiring a Class A CDL.
Yes, it does. If your Class B job requires additional endorsements (such as hazmat, tanker, etc.), you must still have those endorsements on your Class A CDL in order to perform that work.
CDL classes are A, B, and C - there is no Class D CDL.
Depends on which Class of CDL. A driver with a Class C CDL is not licensed on that vehicle. A driver with a Class B CDL can drive that combination only if the GVW of the trailer is less than 10,000 lbs. A driver with a Class A CDL can drive it.
Yes.
Class 3 truck with a rollback body? No, it doesn't require a CDL.
They can work as many hours a day as they wish.. they just can't drive for more than 11, they can't drive after the 14 hour clock is up, etc.
I'd suggest a refresher on Hours of Service regulations if you're a CDL holder and don't understand them. Here's how it works: For anyone with ANY class of CDL (A, B, or C), the daily 14 hour clock begins the moment they start their pre-trip inspection. From the start of the PTI, they have 14 hours in which to complete the 11 hours of driving they are allowed. If they only drive for a couple hours, and the rest is non-driving work, it does not matter - they cannot drive again until they take ten consecutive hours off-duty or in the sleeper berth. You can work as many hours as you wish in a non-driving capacity, but that break must be taken before you get behind the wheel of a CMV again. Also applicable to anyone with any class of CDL is the eight day limit of 70 hours, meaning you can only work a total of 70 hours for the past eight days before you're prohibited from driving a CMV. You can work as many hours in a week as you wish - however, you may not operate a CMV once you've reached the 70 hour mark for the past eight days. You can reset your 70 hour clock by taking 36 consecutive hours off-duty. Some states allow less restricted hours of service for certain special applications, such as oilfield workers. You'd need to check with the state to see if any of those exemptions are applicable to you - bear in mind, those exemptions would only be applicable within the state, not for interstate travel.
You can obtain a CDL class B license at your local DMV. To obtain a CDL class B license you are required to take several tests before obtaining your license.
You will need a Class B CDL with tanker endorsement.
