A standalone system (often with a hydrostatic drive) is usually classed as equipment, and not a highway vehicle, and will not require a CDL. The example coming to mind for me offhand being the Elgin Pelican. A truck-mounted system will require a Class B CDL if the GVW of that chassis exceeds 26,000 lbs.
This answer applies to all states and territories of the US.That depends on the specifics of the sweeper. If it's a sweeping unit mounted on a truck chassis, and that truck chassis has a Gross Vehicle Weight Rating of 26,001 lbs. or more, then yes, it would require a CDL. If it's a purpose-built street sweeper (one example being the Elgin Pelican) then it's considered mobile machinery, and does not require a CDL.
The Elgin Pelicans and Johnston/Globals are considered heavy equipment - not highway vehicles Here in Colorado, they'd be plated as SMM (Special Mobile Machinery) and would not require an upgraded license. Elgin's truck-mounted systems do require a CDL, if they are mounted on a truck chassis with a GVW in excess of 26000 lbs.
If their job function involves operating a vehicle which requires a CDL, then yes.
The CDL is federally administered. If you get a ticket while operating your personal vehicle in another state, it will still show on your MVR for your home state.
If you're operating a vehicle requiring a CDL licenced operator without having a CDL, yes, it is a traffic violation, and one which can cost you dearly, as well.
Level of features
The FMCSA has established 0.04% as the blood alcohol concentration (BAC) level at or above which a CDL commercial motor vehicle operator who is required to have a CDL is deemed to be driving under the influence of alcohol and subject to the disqualification sanctions in the Federal regulations. Most States have established a BAC level of .08% as the level at or above which a person operating a non-commercial motor vehicle is deemed to be driving under the influence of alochol.
If you don't need a CDL operating that vehicle intrastate, you don't need it to operate that vehicle interstate, either.
Only if you're operating it on a commercial, for-hire basis. For personal use, recreational vehicles are exempt from CDL requirements by the FMCSA.
Whatever the employer decides, so long as they meet minimum wage requirements. There isn't one blanket answer for this, as there are three classes of CDL, and a wide variety of jobs which involve operating a vehicle which requires a CDL.
You can repo without one. You only need a CDL if you're going to be operating vehicles or combinations which would require a CDL in normal operation. So, if you're repossessing Class 8 trucks, you'd need a CDL. If you're just repossessing a passenger car, you wouldn't need it.
Are you talking about for a CDL driver, or no? For a CDL driver operating a CMV, you must be at least 18 to drive intrastate, and at least 21 to drive interstate.
