Emergency crews are at the scene of a serious motor vehicle collision on Highway 11 about one kilometre south of Osler.

Warman RCMP say the collision has blocked traffic in the northbound lane. A detour is in place and drivers can expect delays.

RCMP expect northbound traffic will deal with delays for the majority of the evening.

Officers on scene are giving directions for traffic flow; motorists are asked to use caution when travelling in the area by slowing down to 60 kilometres per hour when passing emergency vehicles.
