It's not everyday you see a school bus swerving across lanes on the highway.
So when a number of drivers saw the No. 16 Wallingford-Swarthmore bus crossing the center line on I-476 Monday, they began to follow and call police.
"The bus was erratic and crossed the yellow line the first time," driver Dan Healy said Wednesday.
Healy was driving his son to baseball practice and says that's when he saw the bus almost collided with a van.
As the bus exited the highway towards Swarthmore, Pa., Healy said he flagged down a cop to tell him about the dangerous driver.
"I don't know if [the officer] was going for the bus at this time, but I said 'the bus is erratic, you've gotta do something,' " Healy said.
But police were already searching for the bus because another driver had called 911.
Swarthmore Police finally caught up with the bus at Yale Avenue and Cedar Lane and signaled for the driver to pull over, but not before taking out landscaping and a street sign, police say.
The driver, Christine Rogers, was visibly intoxicated and had an empty bottle of vodka in her purse, police say.
Rogers, 48, was arrested and charged with Driving Under the Influence. Police say her blood alcohol level was tested at .374 -- that's almost five-times over the legal limit, which is .08.
A 16-year-old boy, who was on the bus, was shaken up, but not physically hurt, police say. The school district apologized to the teen and his family.
Michael Norton, the boy's father and a former NBC10 employee, says he was in disbelief to hear that Rogers was drunk.
"Who would ever think that a school bus driver was drunk," he said. "She could've hit somebody, she could've hit another car."
Authorities credit the other drivers for their help in getting Rogers off the road.
"We appreciate the actions of our concerned motorists who gave us the information," Police Chief Brian Craig said. "Otherwise we wouldn't have been able to deal with the situation."
Rogers has been driving for the district for 10-years and has never had a problem, officials say. She resigned after the district started the termination process.
