Family and friends of a Christchurch couple hit by a driver who was going the wrong way down a one-way street are calling for flashing signals to alert other errant drivers.
Friends of crash victims Tony Tucker and Michael Burnby's don't want anyone else to go through what they have.
Close friend to the pair John Lawrence is channelling his despair into a petition calling for better signals to alert drivers who go the wrong way down one-way streets.
"If nothing else [comes] out of this hopefully we can save someone else's life," says Mr Lawrence.
Mr Tucker and Mr Burnby were critically injured when they were hit by a driver who was driving the wrong way down a one-way street 10 days ago. Mr Burnby died in hospital on Wednesday.
The 38-year-old driver who hit the couple died at the scene. Police suspect he had been drinking, but Mr Lawrence says CCTV cameras have established he was driving normally before the crash.
"Down Bealey Ave he was driving correctly, stopping at red lights and then as he was down the one-way system," says Mr Lawrence. "He was driving on the left-hand-side so if we had a flashing light maybe it would have alerted him that he was going the wrong way."
Mr Lawrence's petition is calling for flashing red signals to be installed on the back of one-way traffic lights.
"I think if they had something that clipped onto the bottom of the lights that was flashing that way, it's still in the same eye view."
Motoring analyst Dave Moore says flashing signals might not be the answer, but more could be done.
"A wrong way sign at about shoulder height so it can still be visible when stopped at that traffic light, also when you're coming through," says Mr Moore.
Meanwhile Mr Lawrence's petition is gaining momentum with 700 signatures in just three days.
