The incident occurred during a jog in Santa Monica, Calif., a rep for the actress, 35, confirms to PEOPLE. The driver, an 84-year-old woman, was cited for failing to yield to a pedestrian in a crosswalk, say reports.
Explaining that she was not seriously injured, the rep says Witherspoon is "resting comfortably at home."
Santa Monica police Sgt. Richard Lewis told the Associated Press that Witherspoon was jogging in an unmarked crosswalk when she was struck.
