For example, in some states, a CDL is required to operate a semi-tractor on any public road, even if the road is located on private property. Additionally, some businesses may have their own internal policies requiring employees to have a CDL to operate semi-tractors, even on private property.
Therefore, it is important to check the laws and regulations in your specific jurisdiction to determine whether a CDL is required to operate a semi-tractor on private property.
