A TRAFFIC light sequencing change has been raised as a possible cause for two accidents in two days at a Burnie intersection.
The most recent crash occurred yesterday, which resulted in a woman being hospitalised with critical injuries.
Police said they believed the out-of-sync lights were a contributing factor in yesterday's crash at the intersection of the Bass Highway and Mount Street.
The intersection was also the scene of less-serious crash on Friday night.
Police were called to the crash just before 2pm yesterday.
The crash occurred when a north-bound blue Nissan Pulsar hatch travelling on Mount Street was hit by an east-bound blue Mitsubishi Triton dual cab utility travelling on the Bass Highway.
The Nissan was spun 180 degrees and shunted into the oncoming lanes where it came to rest against the front of a south-bound Toyota Landcruiser travelling on Mount Street.
Police said it appeared one of the vehicles involved failed to stop at a red light.
The front-seat passenger of the Nissan, a 27-year-old woman from Midway Point, sustained critical injuries.
She was taken to the North West Regional Hospital.
The 19-year-old male driver of the Nissan, also of Midway Point, had minor injuries.
The driver of the Mitsubishi, a 46-year-old woman from Upper Castra, had minor injuries and the Toyota's 25-year-old male driver from Burnie was unhurt.
Meanwhile, five vehicles were involved in a crash on Hobart's Tasman Bridge about 5pm yesterday. A man suffered minor injuries.
