2Can a person temporarily operate farm tractor on the highway without driver license?

It depends on the specific laws and regulations in the jurisdiction where you are located. In general, most jurisdictions require a person to have a valid driver's license to operate a farm tractor on a public highway. However, there may be exceptions for certain types of tractors or for temporary operation. For example, some jurisdictions may allow a person to operate a farm tractor on a highway without a license if it is being used for agricultural purposes and the tractor is not exceeding a certain speed limit. It is important to check the specific laws and regulations in your jurisdiction to determine whether a person can temporarily operate a farm tractor on the highway without a driver's license.
