NORRISTOWN, Pa. -- Former U.S. Transportation Secretary Drew Lewis was sentenced to 30 days in jail for drunken driving but will be allowed to serve his time in an alcohol treatment center, according to a wire service.

The judge also ordered him to pay a $5,000 fine and perform 40 days of community service. His license was revoked for 23 months.

Lewis, 70, served in the Reagan administration and is a former chief executive officer of Union Pacific Corp.

He pleaded guilty to drinking on July 23 before he overturned his Lincoln Navigator while pulling out of his driveway in a Philadelphia suburb.

Lewis was arrested after police freed him from his overturned vehicle. At the time of the accident, he had a blood-alcohol content of 0.30 percent, or three times the legal limit in Pennsylvania, said his lawyer, James Maza.

It was his second arrest for driving drunk. After his first arrest in 1995, he completed an alcohol treatment program and spent a year on probation.

A prosecutor said Lewis has already spent nearly six months in a Connecticut treatment center - more than the 30 days ordered by the court - and will be allowed to return to his home when doctors at the center say he is ready to live independently.

Maza said Lewis submitted a letter to the judge before sentencing Wednesday apologizing for his actions.

“I regret and feel quite guilty for all the trouble I caused,” the letter said. “It's a wake-up call I will never forget.”
