Buses and taxis will always attempt to operate unless we have been told that a school/college or adult day centre is closed for the day.
If in attempting a run, the driver feels that to operate a portion of the route would be dangerous then the driver will be unable to operate that portion of the route. Safety of everyone on board a vehicle is paramount, and although in some cases a car may be able to access a road, a bus may not.
Where a driver is unable to operate a portion of the route, this will also apply for the return journey in the afternoon, unless things significantly improve and we are able to inform the school.
