Officials say they received two separate "road rage" calls just before nine Saturday night in the Watertown area.
The road rage complaint involved tailgating, passing and speeding.
The man was eventually arrested for OWI, going armed while intoxicated, and disorderly conduct with a firearm enhancer.
No charges or citations are being requested against the woman.
Sheriff Patricia Ninmann states “This incident could have ended very badly. Drivers who have a complaint about the actions of another driver should contact law enforcement so that it can be handled in the appropriate manne. Thankfully no one was injured and the impaired driver was removed from the roadways.”
