Watch footage from Michael Phelps' second DUI arrest in September.
Olympic swimming star Michael Phelps was sentenced to 18 months probation and a one-year suspended prison sentence on Friday, after pleading guilty to driving under the influence following his arrest leaving a Baltimore casino in September.
Phelps was arrested on Sept. 30 outside the Fort McHenry Tunnel, when he was stopped for speeding and crossing the double yellow line. Police said he was going 84 miles per hour in a 45 miles per hour zone, and registered a 0.14 percent on a blood-alcohol test. The legal limit in Maryland is 0.08.
"I now have the tools to move past this," Phelps told the judge Friday in court, according to the AP. "What I did was wrong, and I made a bad mistake. I'm looking forward to having a much brighter future than I had in the past."

Phelps' attorney, Steven Allen, said he already attended a 45-day treatment program in Arizona, and that he will also participate in Alcoholics Anonymous.
In police footage ET obtained from the incident, the 29-year-old swimming superstar is seen getting handcuffed, and at one point, grins at a police officer while flashing his famous abs.
According to the Maryland Transportation Authority, Phelps was unable to "secure a ride home" after his arrest, so an MDTA police officer drove him back to his home.
