Snow Safety Tips

Never climb a snow mound at a bus stop or wait in an intersection or roadway.
If your bus stop is blocked by snow, walk to the nearest cleared driveway or sidewalk.
Be visible to your driver from a distance and wave to signal you need a ride.
Drivers may stop before or past the usual stop depending on conditions.

When Snow Routes Are in Effect

When a route goes on detour, stops on impassable roads will go out of service. All stops along the detour path will stay in service. Use the detour maps to find your closest active stop.
