If they are lying, their eyes tend to look in a different direction (I think it is up and to the right). If they tell the truth, they look in yet another direction. And if they make something up completely out of the blue, they may look in yet another direction. So, if someone who had been drinking says no, but the cop can see their eyes move in the lying direction, they may continue the questioning and/or field sobriety test. Obviously they won't use it in the courts, but it can be useful.

up and left is visual recall, up and right is visual construction. however some people have it switched. they also said up is sually reacalling dates times etc.
