Just about everyone has found themselves in a situation where they know they shouldn’t drive. Maybe you went out seeing some friends one evening. You planned on having one drink socially, but one thing led to another and in no time, you realize you’re over the limit. Some people try to shrug this off and drive home. These are the people who end up with DUIs.
Police are trained to look at a pack of cars and pick out the drunk driver among them. There’s no secret skill to doing this, there is a science to how people act when they’ve had a few too many and choose to drive. These are a couple of the biggest tells an officer will look for when patrolling for drunks.
