Final answer:
a) Pass a written exam
To downgrade from a commercial to a non-commercial license, one typically needs to surrender their CDL at the DMV and apply for a non-commercial license. The process may vary by state, so it is essential to check with the local DMV.
Step-by-step explanation:
The process of downgrading from a commercial driver’s license (CDL) to a non-commercial license varies by state, but typically, it does not require passing a written exam or completing additional training. Usually, you would need to surrender the commercial license at the Department of Motor Vehicles (DMV) or equivalent state agency, and apply for a non-commercial driver’s license. There is no fine to pay for downgrading unless there is a cost associated with the issuance of a new license. It’s important to check with your local DMV for the precise steps as they can differ from state to state.
