A Utah school bus driver has been charged with driving under the influence of prescription medication with 67 children aboard her bus after terrified chaperones called 911 to report that she was swerving between lanes at 80mph.
Lycia Martinez, 39, had four different prescription drugs with her at the time of her arrest on Monday morning - painkillers, anti-anxiety pills and blood pressure medication, police say. All of them warn that dizziness could be a side effect.
Parents who called 911 were audibly anxious as they described Martinez's erratic driving on Interstate 15 south of Salt Lake City.
'Oh my hell,' the parent said, in an audio recording of the call. 'I don't get scared very easily but my heart is pounding.'
'It's freaking scary and we've got 76 people on this bus. She's nuts.'
'Oh, oh, oh. She almost hit a van.... I am honestly shaking at this point. I'm going to just close my eyes so I see nothing.'
A concerned motorist also called 911 to report the bus.
Martinez was driving the elementary students and eight teachers from Davis County, Utah, north of Salt Lake city to Brigham Young University in Provo - a journey of nearly 60 miles.
The Utah Highway Patrol pulled the bus over south of Salt Lake City shortly after 8am in rush hour traffic on Interstate 15.
