Beckham pulled over during morning rush hour near a roundabout in the town of Ware in England. He assisted photographer Paul Long and his two children.
Long had been ignored by other motorists before the soccer star came to his rescue. He said Beckham asked if they were OK, and Long said he asked for a push to the side of the road.
Long told BBC Radio on Wednesday he said, "Thanks David, I love you" as the former England captain returned to his car.
Beckham is training with Premier League club Tottenham until Feb. 22. He'll soon return to the Los Angeles Galaxy for the MLS season.
