A court has heard a man who is suing a northern Tasmanian council over a car crash 18 years ago could be targeting the wrong authority.
Matthew Peter Guest was 18 when he crashed his car in the Launceston suburb of Riverside in 1994.
The crash killed two of his friends.
He is suing the West Tamar Council for damages over personal injures he suffered in the crash.
He claims the council did not adequately warn him there was a dip in the road.
Associate Justice Stephen Holt questioned whether Mr Guest had sued the right body, saying road signage was not necessarily the responsibility of councils.
The court also heard evidence from retired police sergeant, Mike Davis.
The former accident investigator said the car was travelling about 70 kilometres an hour when it crashed.
The council's defence lawyer is arguing Mr Guest was driving faster than that.
