Narrative:

After being cleared for takeoff at lga runway 4, started normal takeoff with confign of flaps 3 degrees for contaminated runway. Just after V1 and vr started normal rotation and noticed flashing yellow lights out of front windscreen right in front of me. About time main gear was off could see that it was a snow plow. Then I noticed 2 other vehicles on the new runway. When the nose of aircraft was too high to see first vehicle, and we were about to overfly, I could see 1 vehicle that appeared to be on runway also and the third vehicle appeared to be just clear of runway. Crossing ht was approximately 50-75 ft. Reported to tower that vehicles were overflown on runway. Tower then stated over radio, 'who are the vehicles on my runway?' we were then handed off to departure control. I think all vehicles on airport control area should have ATC communication with tower and not just lead vehicle. ATC was working both tower and ground. The same controller shouldn't work both frequencys.

Title: JUST AIRBORNE FROM LGA RWY 4, ACR RPTS TO TWR EQUIP ON RWY DEP END.

Narrative: AFTER BEING CLRED FOR TKOF AT LGA RWY 4, STARTED NORMAL TKOF WITH CONFIGN OF FLAPS 3 DEGS FOR CONTAMINATED RWY. JUST AFTER V1 AND VR STARTED NORMAL ROTATION AND NOTICED FLASHING YELLOW LIGHTS OUT OF FRONT WINDSCREEN RIGHT IN FRONT OF ME. ABOUT TIME MAIN GEAR WAS OFF COULD SEE THAT IT WAS A SNOW PLOW. THEN I NOTICED 2 OTHER VEHICLES ON THE NEW RWY. WHEN THE NOSE OF ACFT WAS TOO HIGH TO SEE FIRST VEHICLE, AND WE WERE ABOUT TO OVERFLY, I COULD SEE 1 VEHICLE THAT APPEARED TO BE ON RWY ALSO AND THE THIRD VEHICLE APPEARED TO BE JUST CLR OF RWY. XING HT WAS APPROX 50-75 FT. RPTED TO TWR THAT VEHICLES WERE OVERFLOWN ON RWY. TWR THEN STATED OVER RADIO, 'WHO ARE THE VEHICLES ON MY RWY?' WE WERE THEN HANDED OFF TO DEP CTL. I THINK ALL VEHICLES ON ARPT CTL AREA SHOULD HAVE ATC COM WITH TWR AND NOT JUST LEAD VEHICLE. ATC WAS WORKING BOTH TWR AND GND. THE SAME CTLR SHOULDN'T WORK BOTH FREQS.
