Narrative:

After the 100 ft call by the aircraft; the first officer (pilot not flying) said; 'what is that; a truck?' he started talking about a possible go-around. I changed my focus further down the runway and saw an emergency vehicle clearing about midfield on the north side and didn't notice any other vehicle following across the runway. I made a decision to continue to land; which went uneventfully and; while clearing; the first officer queried the tower about the truck. We had heard nothing from tower at all. The tower controller said there had been a communication error with the truck. We heard the tower controller ask the truck to call them. We proceeded to call our ATC specialist to get him in the loop.
