Ty Pennington has spoken out about his May 5 arrest
for alleged drunk driving.
"I made a really bad error in judgment," the Extreme Makeover: Home Edition
host, 42, tells Entertainment Tonight
Pennington says of his brush with the law: "It made me realize how important every decision you make in your life is because it affects everyone, not just yourself."
At the time of his arrest in the Marina Del Rey section of Los Angeles, Pennington's blood-alcohol level was .14 percent – well above the state's legal limit of .08 percent, Los Angeles City Attorney spokesman Frank Mateljan told PEOPLE.
He was charged on May 8
with two misdemeanors: driving under the influence and driving with a blood-alcohol level of .08 or higher. If convicted, he faces up to six months in jail.
"I realized if you make a mistake, I think you ought to step up and admit that you did," Pennington tells E.T.
"I'm just that kind of a person. If you do something that you know you shouldn't have, stand up and accept it."
He also owns up to the severity of his actions. "It could jeopardize everything, including my job, which to me, is the greatest job in the world," he says. "I would never want to jeopardize that. I get to do something that a lot of people never get to do in their lifetime and actually get to make a difference in people's lives."
Asked what he might have done differently that fateful day, he replies: "Probably take a cab. But if we could hit rewind in our life, I think we would do a bunch of things differently. But you can't do that. All you can do is accept what's happened and learn from it."
