Los Angeles, CA- Former Partridge Family star David Cassidy managed to avoid jail for his first two DUI arrests. But his third DUI, from earlier this month, just may land the 70s heart throb in the slammer, but not for too long.

Cassidy was formally charged with DUI today and Los Angeles city attorney told gossip hounds TMZ he will spend at least 96 hours in the slammer. But he could spend up to one year in jail unless he has a convincing DUI attorney.

Cassidy was arrested on January 10th in Los Angeles after an officer observed his making an illegal right turn. He failed field sobriety tests and he blew twice the legal limit on a breathalyzer.

Immediately after the arrest, his agent Jo-Ann Geffen tried to do damage control and said Cassidy had successfully completed rehab and was living a sober life. She says the legal battle between Cassidy and Sony pictures over royalties from the popular 70s show The Partridge Family.

“David just completed a stint in rehab and was doing very well in sobriety,” Geffen said, according to the Daily Mail. “After attending his and his manager’s depositions, it appears as if the pressure led to a brief relapse.”

Geffen said Cassidy was headed to the Los Angeles airport to return to Ft. Lauderdale, Florida where he lives.

Cassidy went into rehab after he was arrested for driving under the influence in New York State last August. He registered a 0.10 on a breathalyzer for this arrest and his DUI was upgraded from a misdemeanor to a felony because of his prior arrest.

After his second arrest, Shirley Jones, who played the matriarch of the Partridge Family said Cassidy was dealing “demons” that he was struggling to control, referring to the singer’s drinking problem.

Cassidy got his first DUI in 2010 when he was stopped in Florida for driving erratically. Police found an open bottle of whiskey in car and his BAC was twice the legal limit. He pleaded no contest for that charge and was sentenced to one year of probation, fifty hours of community service and lost his driver’s license for six months.

For his third DUI, on top of the mandatory 96 hours in jail, Cassidy will likely have to install an ignition interlock device in his vehicle. It doesn’t matter if his conviction is California his license will still be suspended in his home state since the Department of Motor Vehicles shares information about suspended licenses with other states with a few exceptions.

Wisconsin, Tennessee, Georgia, Massachusetts, and Michigan are the handful of states that don’t report DUI convictions to other states. All other states require the offender to attend alcohol assessment classes and fulfill their other sentencing obligations in the state where they were arrested before their license is reinstated in their home state.

Being charged with a DUI in a state other than your home state can seriously complicate your life. It is very difficult to face an out-of-state drunk driving charge without the assistance of DUI attorney. Don’t make the mistake of thinking you can handle a DUI on your own.
