Narrative:

After being cleared to land on runway 4 at laguardia airport and executing a normal ILS (flown in VMC). As the power was reduced to idle in the touchdown zone, the captain noticed a vehicle off to the left side of runway 4. As the main gear contacted the runway the vehicle proceeded onto the runway. The vehicle (an airport vehicle with a yellow flashing light) stopped on the runway centerline and turned toward the aircraft, I lowered the nosewheel onto the runway and applied maximum braking and normal reverse thrust to insure that we would be able to hold short of the airport vehicle. Shortly after I applied maximum braking and normal reverse thrust, the airport vehicle made an abrupt right turn and exited runway 4 to the west side of laguardia airport. As we cleared runway 4 on golf taxiway, the captain asked the tower about the vehicle, to which the tower controller replied that there was no vehicle that he observed on runway 4. Supplemental information from acn 267191: the vehicle was on the runway for approximately 3-5 seconds total and was clear of the runway before the aircraft came to a stop. Because runway 13-31 was closed, the activity of vehicles with flashing lights were observed but was not a concern due to the NOTAM. I feel our actions of continuing the landing with maximum braking was appropriate due to the vehicles' location. If we had aborted the landing, which would have resulted in a touch and go landing, this could have put us in a more dangerous situation by placing the aircraft closer to the vehicle at a high rate of speed.

Title: AN ACR MLG REINED UP SHORT TO AVOID A VEHICLE ON THE RWY.

Narrative: AFTER BEING CLRED TO LAND ON RWY 4 AT LAGUARDIA ARPT AND EXECUTING A NORMAL ILS (FLOWN IN VMC). AS THE PWR WAS REDUCED TO IDLE IN THE TOUCHDOWN ZONE, THE CAPT NOTICED A VEHICLE OFF TO THE L SIDE OF RWY 4. AS THE MAIN GEAR CONTACTED THE RWY THE VEHICLE PROCEEDED ONTO THE RWY. THE VEHICLE (AN ARPT VEHICLE WITH A YELLOW FLASHING LIGHT) STOPPED ON THE RWY CTRLINE AND TURNED TOWARD THE ACFT, I LOWERED THE NOSEWHEEL ONTO THE RWY AND APPLIED MAX BRAKING AND NORMAL REVERSE THRUST TO INSURE THAT WE WOULD BE ABLE TO HOLD SHORT OF THE ARPT VEHICLE. SHORTLY AFTER I APPLIED MAX BRAKING AND NORMAL REVERSE THRUST, THE ARPT VEHICLE MADE AN ABRUPT R TURN AND EXITED RWY 4 TO THE W SIDE OF LAGUARDIA ARPT. AS WE CLRED RWY 4 ON GOLF TXWY, THE CAPT ASKED THE TWR ABOUT THE VEHICLE, TO WHICH THE TWR CTLR REPLIED THAT THERE WAS NO VEHICLE THAT HE OBSERVED ON RWY 4. SUPPLEMENTAL INFO FROM ACN 267191: THE VEHICLE WAS ON THE RWY FOR APPROX 3-5 SECONDS TOTAL AND WAS CLR OF THE RWY BEFORE THE ACFT CAME TO A STOP. BECAUSE RWY 13-31 WAS CLOSED, THE ACTIVITY OF VEHICLES WITH FLASHING LIGHTS WERE OBSERVED BUT WAS NOT A CONCERN DUE TO THE NOTAM. I FEEL OUR ACTIONS OF CONTINUING THE LNDG WITH MAX BRAKING WAS APPROPRIATE DUE TO THE VEHICLES' LOCATION. IF WE HAD ABORTED THE LNDG, WHICH WOULD HAVE RESULTED IN A TOUCH AND GO LNDG, THIS COULD HAVE PUT US IN A MORE DANGEROUS SIT BY PLACING THE ACFT CLOSER TO THE VEHICLE AT A HIGH RATE OF SPD.
