Final answer:
The truthfulness of the statement regarding operating a farm tractor on the highway without a class E driver's license can vary based on local traffic laws and regulations; thus, it is not universally true. Local laws should be consulted for accurate information.
Step-by-step explanation:
The legality of operating farm equipment on public highways varies depending on the jurisdiction. However, it is not universally true that one cannot operate a farm tractor on the highway without a class E driver's license. Licensing requirements for driving a farm tractor on the highway can differ, and in some places, there may be exceptions or special licenses available for farm equipment operators. These often depend on factors such as the size and type of the tractor, the distance traveled on the highway, and whether the operator is performing farm-related activities. To obtain the most accurate information, it's best to consult local traffic laws and regulations or speak with the local department of motor vehicles.
