Police are working to identify the body of the man who was struck by a car on the Bass Highway during heavy rain.

The accident came after the death of an 82-year-old man in hospital on Saturday morning as the result of a road crash.

The Elizabeth Town man was involved in a two-car crash on Tuesday near Elizabeth Town that police believed was caused by inattention.

In Saturday's accident near East Devonport, the cyclist was travelling east in a west-bound lane when he collided with a west- bound white Toyota Hiace after 7pm.

The rider was thrown from the bicycle and hit by several other cars.

The crash was reported to police at 7.25pm and occurred 600 metres from the Port Sorell overpass.

First Class Constable Colin Willcox, of Burnie Accident Investigation Services, said heavy rain reduced visibility on the road.

Constable Willcox said speed was not a contributing factor to the crash.

Police said the Toyota van involved in Saturday night's fatality was driven by a 32-year-old man from Deloraine who was wearing a seatbelt.

Efforts to identify the body of the rider of the motorised bicycle will continue today.

Bass Highway traffic was diverted for four hours while crews worked to clean up debris.

Both deaths come less than two weeks after Tasmania recorded its worst day on the roads, with nine fatalities in one day.

At 50, Tasmania's road toll is 10 more than its total for 2008.

The staggering road toll has angered the State Opposition, which has vowed to make drivers understand that it is a privilege, not a right, to be on the roads.

At the State Liberal conference at the weekend, Opposition Leader Will Hodgman and infrastructure spokesman Jeremy Rockliff pledged to introduce driver education in years 9 and 10.

Anyone who saw the van or the bike before the crash is asked to contact Burnie Accident Investigation Services on 64 34 5276 or 131 444.
