THE ACFT COLLIDED WITH A TRUCK DURING TAKEOFF GROUND RUN FROM AN INTERSTATE. THE PLT INDICATED THE ACFT HAD RUN OUT OF FUEL ON THE X-COUNTRY FLT AND HE HAD NOT REFUELED AT THE DEPARTURE POINT. HE LANDED ON THE INTERSTATE WITHOUT INCIDENT AND SENT HIS PAX FOR FUEL. THE PAX RETURNED WITH APPROXIMATELY 10 GALS OF 100 LL. SEVERAL TRUCKERS STOPPED THE HWY TRAFFIC IN THE EASTBOUND LANES SO THE PLT COULD TAKEOFF. A TRUCK WAS PARKED APPROXIMATELY 600 FT FROM THE START POINT IN THE RIGHT EMERGENCY LANE (SOUTH SIDE OF EASTBOUND LANES.) THE PLT INITIATED A SOLO TAKEOFF FROM THE INTERSTATE AND THE ACFT ACCELERATED TO APPROXIMATELY 40 KNOTS. AS THE ACFT PASSED THE TRUCK THE RIGHT WING TIP STRUCK THE REAR CORNER OF THE TRUCK GROUND LOOPING THE ACFT INTO THE TRUCK'S LEFT SIDE. THE WINDS AT AN AIRPORT LOCATED 40 MILES TO THE EAST WERE REPORTED FROM THE NORTH AT 12 KNOTS AT THE TIME OF THE ACCIDENT.
