A fatal car crash that changed one family's life forever started a push to change the law in California concerning "party buses."
Brett Studebaker, 19, of Burlingame died nearly two years ago during a "booze cruise" around San Francisco after a night of drinking on a "party bus."
Studebaker was dropped off at 2 a.m. He was drunk and crashed his car on his way home.
The new law, named after the teenager, will now hold tour company's accountable for underage drinking.
Brett's father, Doug Studebaker, noted that three people have died in California since his son's death and the signing of the law. "We feel Brett's presence quite a bit. We know that he is smiling down on this day," Doug Studebaker said Tuesday.
Under AB45, a bus company is required to ask if there will be anyone under 21 years old on the bus. If there are, a chaperone of at least 25 years old must accompany the group and be responsible for making sure those under the legal drinking age aren't drinking. Bus drivers also have to check IDs.
It was signed over the weekend by Gov. Jerry Brown. It won't take effect until Jan. 1
