What type of license must applicants possess?

Applicants must possess a valid driver's license to ensure they meet the basic requirements for operating a vehicle legally and safely. A valid driver's license indicates that the individual has undergone the necessary training and testing to demonstrate their competency in driving, which is crucial for anyone entering law enforcement. This requirement aligns with the responsibilities of police officers, who must navigate public roads and respond to emergencies effectively.

A commercial driver's license, while important for operating large or specialized vehicles, is not a universal requirement for all law enforcement roles. Similarly, a motorcycle license or a restricted driving permit caters to specific driving needs or limitations but does not meet the broader requirement of possessing a valid driver's license. Therefore, the correct answer emphasizes the fundamental need for drivers in law enforcement to have a general valid driver's license to serve and operate in their duties.
