The Oklahoma ABLE Commission is working to better inform casino staff across the state about drunk driving and underage drinking.
Oklahoma is ranked as one of the worst when it comes to preventing DUI fatalities.
"Oklahoma's DUI numbers are terrible," said ABLE Commission Senior Agent Erik Smoot.
Smoot said too often, people who have had too much to drink get behind the wheel and onto I-44 all the time.
"I came here and I trained 400 of their employees," said Smoot.
The Hard Rock Casino called him in to instruct a three-hour course.
"They made their security people go through this training," said Smoot. "They made their valets go through this training."
You must be 21 to play here, but not every casino enforces that rule. Some say if you're 18, you can gamble.
"That's like an 18-year-old bar, that's hard to manage," said Smoot.
Rather than take a chance, more casinos are seeking his services.
"We're 47th in the nation in alcohol-related deaths," said Smoot.
Smoot has already taught five courses this week across the state.
It's not a guarantee that people won't stumble into their car and onto the road, but Smoot's classes help the odds.
