Norman, Oklahoma Roadblocks

This roadblock has been set up three times in the past 2 years, usually during the summer. Twice it appeared to be a sobriety check for Memorial Day for Lake Thunderbird; another time it served no purpose we could think of except for revenue generation (this was about 4 pm on a weekday). During the times we encountered this roadblock we were required to produce drivers licenses (both driver and pax) and insurance cards.
