The 66-year-old women from Enderby was hit Nov. 17 on Highway 6 in Lavington, where she was directing traffic.
The flagger was flown to Kelowna General Hospital by air ambulance.
At the time Cpl. Annie Linteau said police attended a construction zone on Highway 6 in Lavington between School Road and Hill Drive after receiving a report that a traffic control person had been hit by a vehicle.
“Early indications are that a west-bound vehicle approached the construction zone and was apparently stopped by the traffic control person in an area reduced to one-lane of traffic,” said Linteau. “It appears the driver of the vehicle involved was unable to stop in time and hit the traffic-control person.”
“The 75-year-old driver of the vehicle involved is co-operating with the investigation and a number of witnesses have been identified,” said Linteau.
Police are continuing their investigation.
