There is a bit more to this than most people imagine. It depends on whether the road is existing or newly surfaced. For an existing road, it's as simple as going over the old ones, so a basic truck and paint system is used as previously mentioned by other members. If it is a newly surface road and there are no existing markings, then it gets a bit more technical.
When a new road is finished, a surveyor makes sure the road is as it should be (straight edges etc). The truck used to paint the lines has an infared system to judge the edges of the road and to look straight ahead to keep straight. Newer systems also use a gps system that is good to +/- 1inch. The spped of the truck, the length of the line etc, is all pretty automatic.

There is a truck they use that has a paint sprayer on it. The sprayer nozzle is held at a constant height above the road. This creates a straight line as the truck moves slowly down the road.

I have actully seen them paint the lines on a road. I was stuck behind the SOB for about 2 miles. there is a truck and off the left side of the truck aboput 12 inches off the ground there is a spray arm. for dashes they turn it on and off. for a line they leave the spray on. the prob is they have to drive real real real slow.

i think they have good hand and eye coordination and plus they are skilled at measuring the angles length and width of the lines.
