During takeoff roll, at approximately V1, flight crew of a cpr jet observed a vehicle coming toward them on the runway and subsequently go off the side of the runway prior to their aircraft flying over at approximately 50 ft. The tower had failed to check the runway after clearing the vehicle on the runway earlier.

Narrative:

Tower cleared us onto runway 26, cleared for takeoff. Well into our takeoff roll (approaching V1) we spot a vehicle on the runway driving towards us! Best decision/reaction was to flash lights continuing through rotation. Vehicle pulled off onto grass at south side and horizontal separation at that time was approximately 1000-1500 ft. We overflew the area where the vehicle had been with approximately 50-100 ft of vertical separation. I informed the tower. Evidently, tower personnel failed to realize they had cleared the ground vehicle and later cleared us without checking.

Original NASA ASRS Text

Title: DURING TKOF ROLL, AT APPROX V1, FLC OF A CPR JET OBSERVED A VEHICLE COMING TOWARD THEM ON THE RWY AND SUBSEQUENTLY GO OFF THE SIDE OF THE RWY PRIOR TO THEIR ACFT FLYING OVER AT APPROX 50 FT. THE TWR HAD FAILED TO CHK THE RWY AFTER CLRING THE VEHICLE ON THE RWY EARLIER.

Narrative: TWR CLRED US ONTO RWY 26, CLRED FOR TKOF. WELL INTO OUR TKOF ROLL (APCHING V1) WE SPOT A VEHICLE ON THE RWY DRIVING TOWARDS US! BEST DECISION/REACTION WAS TO FLASH LIGHTS CONTINUING THROUGH ROTATION. VEHICLE PULLED OFF ONTO GRASS AT S SIDE AND HORIZ SEPARATION AT THAT TIME WAS APPROX 1000-1500 FT. WE OVERFLEW THE AREA WHERE THE VEHICLE HAD BEEN WITH APPROX 50-100 FT OF VERT SEPARATION. I INFORMED THE TWR. EVIDENTLY, TWR PERSONNEL FAILED TO REALIZE THEY HAD CLRED THE GND VEHICLE AND LATER CLRED US WITHOUT CHKING.
