Speed to Spare is an efficient entry from the Pine-Thomas Productions assembly line. Ricard Arlen, who'd been a "regular" with the P-T output since the early 1940s, stars as daredevil auto racer Cliff Jordan. Opting for a safer profession, Jordan forms a trucking firm with his somewhat more even-tempered pal Jerry (Richard Travis). Before long, however, the reckless Jordan once more finds himself in hot water, courtesy of all-around villain Pusher (Ian McDonald), the head of a rival trucking concern. Though billed third, Jean Rogers has little to do other than register concern over the carefree Jordan.
