A 42-year-old school bus driver has been suspended from her duties and charged with impaired driving after a school bus carrying young children crashed into a tree and a traffic sign in a residential neighbourhood of Red Deer earlier this week.

Emergency crews were called around 4 p.m. local time Monday, following reports of a single-vehicle crash involving a school bus. There were 18 elementary school students, ranging in age from five to 12, on the school bus at the time of the incident. The students attend Ecole Barrie Wilson Elementary School.

Red Deer RCMP said a witness called them after seeing the bus hit a tree and sign.

According to Mounties, the driver kept going for a couple of blocks before coming to a stop. No one was injured.

Shelly Joy Kolodychuk, 42, of Red Deer, has been charged with impaired operation of a motor vehicle, operating a motor vehicle with a blood alcohol volume of over 80 milligrams, dangerous operation of a motor vehicle and failing to remain at the scene of a collision.

CTV Edmonton reports that Kolodychuk was an employee of charter bus company Prairie Bus Lines. The company told CTV that she has been suspended pending the outcome of a full investigation.

In a statement to CTV News, Red Deer Public School District Superintendent Stu Henry said the school board is “deeply concerned and shocked” by the alleged incident, and will “continue to monitor the situation and take every precaution” to assure parents and students that it was isolated.
