AP 551 - Operation of School Buses Under Adverse Weather

Primary consideration as to whether the bus will run shall be the safety of the students. In the event that the driver is making the run under what could be considered as “questionable” conditions, it is the responsibility of the parent to make the decision as to whether to send their children on the bus.

Significant care and attention to the following procedures by bus drivers is required when weather presents dangers to safe school bus operations.


1.  The bus driver shall not transport children to school if the temperature is in excess of minus 40 degrees Celsius, or minus 45 degrees Celsius with a wind chill.

2.  The bus driver, keeping the safety of the students in the forefront, shall use his/her best judgment in determining whether or not to run the bus route under the following conditions:

  • Blizzard conditions;
  • Poor visibility;
  • Fog;
  • Freezing rain; and,
  • Other unsafe road conditions.
3.  If the condition of the road is such that it may be harmful to the students, driver and/or bus, the drivers are asked to pick up only those students that can be picked up safely. At no time should the bus to go through mud and snow that may be harmful to the driver and passengers, or cause damage to the bus.

4.  Should a driver decide not to run on any particular route, he/she shall make the final decision and not be influenced by the actions of other drivers within the area. However, the safety of the students shall be paramount and will be monitored by Transportation Services.

5.  Should a storm or other dangerous climatic conditions arise during the day while the students are in school and it is not possible for an end of the school day departure, then students will be billeted. Under no circumstances should buses start on their route in the height of a winter, or any storm.

6.  Only in an emergency school closure should buses leave at a time other than regularly designated. Please refer to AP 129 – Emergency School Closure for more information.

7.  When a bus driver makes the decision not to make a run, then he/she shall contact the principal(s) of the school(s) affected and notify the parents on the route.

8.  When a principal receives notification from the bus driver that the route has been cancelled, the principal shall notify Transportation Services using the Bus Cancellation link located at the top of their school’s website page.  The information submitted must include:
  • Date;
  • am/pm run;
  • Route ID; and,
  • Reason for cancellation. 
9.  The Principal may also choose to contact the local radio stations in their area to announce the bus cancellation.
