Only if the vehicle has a Gross Vehicle Weight Rating of 26,000 lbs. or less (and remains under that weight). Otherwise, you need a CDL.
If the vehicle requires a CDL in service, it'll require a CDL for the test drive.
That depends on exactly what you're driving. A pickup truck with a snowplow mounted on the front doesn't require a CDL. A single axle dump truck weighing under 26,000 lbs doesn't, either. The moment that vehicle weighs over 26,000 lbs., or if you're driving a tandem/tri-axle/quad axle/etc. dump truck with a plow, then you need a Class B CDL. If, at any point, you're driving a combination (of truck and trailer) with a Gross Vehicle Weight Rating of over 26,000 lbs, and the vehicle in tow is rated at over 10,000 lbs, then you need a Class A CDL.
Yes, you will need insurance to drive with a CDL license.
You can drive vehicles which require the operator to possess a 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.
A CDL license is required to drive a skid loader. Many employers will require a CDL to get positions that require the operation of a skid loader.
Your CDL permit is in addition to the class of licence you had beforehand. So long as you were licenced to drive a car before you got your CDL permit, you can drive your own car while you possess a CDL permit.
In most cases they drive the plow home therefore they drive it to work also.
Can I drive a farm dumptruck without a cdl in Washington State
It depends on the model. You need a CDL to drive one that bends in the middle or is over a certain length
Yes, just as you do with any other car or truck...
11, as per federal law. That applies both for local drivers and OTR drivers. The only variance you'll find to that is the case of vehicles providing an emergency service (e.g., snowplow trucks, contracted FEMA vehicles, etc.).
