Operating a vehicle under the influence of alcohol is classified as drunk driving because it directly pertains to the impairment of the driver's ability to operate a motor vehicle safely due to the consumption of alcohol. Legally, a driver is considered to be operating under the influence when their blood alcohol concentration (BAC) is above a certain limit, typically 0.08% in many jurisdictions, including California. This classification is significant because it addresses public safety risks associated with impaired driving and helps enforce laws designed to reduce accidents and fatalities due to drunk driving.

The other scenarios presented do not involve a driver's impairment due to alcohol consumption. Driving without a license, refusing to provide identification, and driving with expired registration are violations of vehicle operation laws but do not specifically relate to the influence of alcohol on driving capabilities. As such, they do not fall under the classification of drunk driving.
