The city of St. John's and the Department of Transportation and Works went on trial Wednesday in St. John's in connection with a fatal accident on the Outer Ring Road in 2011.
Joseph English, an engineer with the provincial government, was killed in July 2011 when a driver lost control and veered off the highway, striking English and two other men.
English, 51, died at the scene.
In court on Wednesday, the first Royal Newfoundland Constabulary officer to arrive at the scene of the accident said the driver of the SUV that struck the workers was in shock after the accident.
That officer, and an accident investigator with the RNC, testified they did not see any signage to indicate to drivers that road workers were on the scene.
Of the other two men injured, one was a city worker and the other was a sales representative with Irving Oil.
The three men were on the road that day to inspect asphalt, made by Irving Oil, and figure out why it was deteriorating faster than expected.
In May 2014, Irving pleaded guilty to safety regulations for not providing its employee with proper safety instruction and clothing, even though the accident report by the RNC said safety clothing would not have made a difference.
The City of St. John's and the Department of Transportation and Works both pleaded not guilty to similar violations.
Irving Oil was fined $13,500 and had to give the Newfoundland and Labrador government $2,000 to help provide safety education for roadway workers.
The trial is slated for 16 days
