Cinco de Mayo is on Sunday and it's one of the biggest celebrations of the year in Arizona.
The parties are already getting underway, which means the roads are more dangerous.
Starting Wednesday, May 1st, a huge statewide DUI crackdown begins and it will last through Sunday.
And just like every year, officers on patrol will arrest hundreds of drivers who decide to get behind the wheel after just "having a few."
In 2011, 541 DUI arrests were reported by the Arizona Governors Office of Highway Safety. 178 were arrested for extreme DUI -- a blood alcohol level at or above 0.15 percent.
In 2012, 490 arrests were made, of which 146 were extreme.
People say "I just had a couple," so how many beers does it take to blow a 0.08?
