Three people are in hospital after a car towing another vehicle and a van crashed on the Midland Highway, north of Campbell Town.
Senior Sergeant Michael Gillies said a black Ford Falcon was towing another vehicle when the trailer started to fishtail and the driver lost control.
"As a result his vehicle has been forced into the other lane into the oncoming traffic, being the Armaguard van," he said.
"Luckily, there were only some minor injuries and a passenger in the black vehicle has received some leg injuries and possibly lower body injuries, but it's not life threatening."
The females passenger of the Falcon was flown to the Royal Hobart Hospital by the Westpac Rescue Helicopter after sustaining the non-life threatening injuries.
The two men who were in the vehicle with the injured woman have been transported to the Launceston General Hospital with minor injuries.
The two people who were in the van were not physically injured.
Police are investigating the cause of the crash.
"Part of the investigation will be to look at the towing capacity of the vehicle," Senior Sergeant Gillies said.
"We'll be looking at speed as a factor in the accident, but at this stage we haven't gotten anything concrete to say that they someone was traveling too fast."
