Two people have been taken to hospital after a series of crashes involving eight cars and a bus on a major Tasmanian road south of Launceston.
Illawarra Road at Longford was closed for several hours this morning between the Bass and Midland highways.
The road is a popular thoroughfare between the two highways.
Acting Sergeant Casey Wood said there were three separate crashes, one after the other, on the stretch of road around 8am.
She said the first incident was sparked when someone had "pulled over slightly on the side of the road", but investigations were continuing.
The wet road, sun and fog contributed to several other cars crashing in the next incident, Acting Sergeant Wood said.
All those factors led to the third crash, which involved a bus holding two people and several cars, she said.
Acting Sergeant Wood said two people had been taken to hospital with non-life-threatening injuries.
"Please drive to the conditions. If the roads are wet and there's fog, we really need to slow down and be mindful of other road users," she said.
Illawarra Road reopened late in the morning after the vehicles and debris were cleared from the road.
