Yes, that's a cadet driving the Jeep.
CAP had a friend in Milton Caniff, author and illustrator of several comics including the Steve Canyon comics. The Steve Canyon character was an upstanding Air Force officer who recruited, and sometimes worked with, CAP Cadets. Mr. Caniff published three CAP specific comic books. He also published a regular Steve Canyon comic strip that also featured female CAP cadets: Scooter McGruder, Bitsy Beekman, and Poteet Canyon.
