"Prison Break" star Wentworth Miller had his own brush with the law over the summer.

He was pulled over twice for speeding, in two states. The incidents had two different outcomes.

The first time was when Miller, who plays the tattoo-laden Michael on the hit Fox drama, was nailed in Iowa for doing 85 in an 80-mph zone.

"It didn't even occur to me to play The Card," he says, referring to using his celebrity to get out of a ticket.

But the policeman was willing to fold once he took Miller's license and registration information.

"Where did you come from?" Miller remembers the policeman asking.

"Chicago," Miller said.

"And what do you do there?" the officer asked.

"I'm on a show called 'Prison Break,' " Miller recalls telling him.

Turns out that the officer's wife was a big fan of the show.

"Guess who got off with a warning?" Miller says with a laugh. "I felt a little guilty driving away."

A similar thing happened in Utah, but with a different ending.

"I was pulled over doing 80 in a 75 [mph zone] in Utah," Miller says. "The cop was ready to bust me for it."

And he did.

Yes, it was a "bummer," says Miller, but "you got to play by the rules."

The roadside action was part of his summer vacation.

Instead of working on other projects during his break, he got in his Toyota Corolla and drove solo from Chicago to Los Angeles.

Miller says he was seeking a stress-free adventure away from scripts and network executives.

He'd stop into diners and at gas stations, where he'd meet up with fans.

In the second season (beginning at 8 tonight on Fox), Michael and his brother, Lincoln, finally bust free and are on the lam.

Outside the prison, Michael will be a different person, Miller says. He says he will explore other sides of his character.

In one episode, the stone-faced Michael will even laugh.

"I told the writers when Michael is in prison he is a man with a mission. He is guarded," Miller says.

"But when he is off with his brother, away from [prison], he is allowed to show a side of himself that he is not allowed to show [when] others [are present]."
