Court documents show that the driver of a school bus that went off the road and crashed near Lyons, on Monday, was taking six prescription medications.
Investigators say Elizabeth Burris was "unsure if she named them all."
Burris was reported to be driving erratically and crashed shortly after, rolling the school bus onto its side.
Burris told police that she drifted off the road, attempted to gain control and over-corrected.
The accident injured five of the eight students on board.

Two of the children (15-years old) suffered serious injuries and three suffered minor injuries.
The St. Vrain Valley School district did not return phone calls or emails seeking comment about the crash.
Burris has been with the district for about two years.
In court Tuesday, Boulder County Court Judge Noel Blum advised Burris that she was being held for investigation on multiple counts of Child Abuse, Vehicular Assault, DUI and Careless Driving resulting in injury.
Bond was set at $2,500 cash, surety, property. She bonded out of jail Tuesday evening.
She is due back in court December 10 at 1:30 p.m.
