Which of the following is NOT a step in upgrading an operator’s license?

The process of upgrading an operator's license typically involves steps that ensure the individual is prepared and qualified to operate a vehicle safely. Receiving a learner's permit allows the operator to practice driving under the supervision of a qualified driver, which is crucial for building foundational skills. Conducting a road skills test is an essential part of the licensing process because it assesses the driver's ability to operate a vehicle safely in real-world conditions. Having medical screening is often a necessary step to ensure that the operator does not have any medical conditions that would impair driving ability.

In contrast, submitting a written essay is not a common requirement in the process of upgrading an operator's license. While written tests may be part of the process to assess knowledge of traffic laws and road signs, an essay is not standard practice and does not contribute to assessing driving skills or knowledge in the way that the other steps do. Thus, this option stands out as not being a typical part of the licensing upgrade process.
