What document must a person possess while operating a motor vehicle under an occupational license?

A certified copy of the court order is essential for a person operating a motor vehicle under an occupational license because it serves as legal evidence of the restrictions placed on the individual's driving privileges. An occupational license is typically granted to individuals who have lost their regular driving privileges due to certain offenses, allowing them to drive under specific circumstances, such as for work or essential purposes.

The court order outlines the terms under which the occupational license is granted, including details about where and when the individual is allowed to drive. Without this document, the individual may not be able to prove that they have the right to operate the vehicle legally under the limits set by the court, thus leading to potential legal penalties.

While having the original driver's license, proof of insurance, and vehicle registration is also important for lawful driving, they do not specifically validate the individual's authority to drive under the constraints of an occupational license. The court order directly addresses the necessity of the occupational driving privileges, making it the critical document in this context.
