A squad car video shows a Wisconsin lawmaker falling down during a sobriety test that led to his third arrest in less than a year on suspicion of driving under the influence.

The video released Tuesday by Tomah police shows Rep. Jeffrey Wood getting pulled over after officers see his Buick Skylark stop in the middle of a road and then slowly swerve across both lanes of traffic.

When Wood is asked to walk a straight line, he stumbles backward into his car before falling down into some grass. An officer helps him up, and Wood is put in handcuffs a short time later.

The video also shows police seizing bottles of prescription drugs from Wood.

He was charged last week with third-offense operating under the influence of an intoxicant and bail jumping. He has apologized for his actions and says he won't seek re-election next year.
