Saturday 9th February 1952

A two-way radio was first used in NASCAR competition. Al Stevens, who operated a radio dispatch service in Maryland, drove in the 100-mile Modified and Sportsman race at Daytona while talking to pit boss Cotton Bennett. Stevens finished 27th in the 118-car field and third in the Sportsman class. Tim Flock was flagged the winner, but was disqualified when NASCAR technical inspectors find “improper” roll bars in his 1939 Ford. Jack Smith was declared the ­official winner.
