Field sobriety tests are expected to be conducted at DUI checkpoints throughout California on New Year's Eve.
A San Mateo County bus driver has been arrested on suspicion of driving under the influence after she crashed into a car at a stop light.
Matteucci says the Avalon driver called police after she noticed that Tebo-Davis appeared confused and unable to provide basic information after the crash.
Police say Tebo-Davis told them she had taken some prescription medication.
Stanley Davis Sr., who identified himself in a phone interview with Contra Costa Time as the woman's husband, said his wife takes painkillers such as Vicodin due to back pain and has become addicted to them.
"She overmedicates," Davis told the paper, adding that he had not seen his wife since Friday.
SamTrans spokeswoman Christine Dunn says the bus driver is an employee of MV Transportation, a contractor for the transit agency. She declined comment on what discipline Tebo-Davis might receive.
One passenger was aboard the special disabilities bus at the time, but no injuries were reported.
