Police are urging anyone who may have witnessed a horrific crash that killed two people on Western Australia's Bussell Highway on the weekend to come forward.
The accident occurred near Capel at about 1:00pm on Sunday afternoon when a grey Skoda Yeti driving north collided head on with a Toyota Land Cruiser.
The 36-year-old driver of the Skoda and his 31-year-old female passenger died at the scene.
The male driver of the other vehicle was taken to Bunbury Regional Hospital and his female passenger was flown to Royal Perth Hospital.
Travellers on the Bussell Highway came across the scene before police arrived.
South West Police Superintendent Geoff Stewart said anyone who witnessed the scene may need to seek help.
"I just encourage anyone who saw [traumatic things] to talk to someone," he said.
Notorious stretch of road
The Bussell Highway is the major road linking Bunbury to the popular holiday destinations of Busselton and Margaret River.
Road works are currently underway to widen a section of the highway between Capel and Busselton that is notoriously dangerous and busy, particularly on weekends and during holidays.
In 2019 a survey compiled by insurer RAC labelled the Bussell Highway the riskiest road in regional WA due to its lack of overtaking opportunities and traffic separation.
Superintendent Stewart told the ABC he was concerned about the upcoming tourist season, which was expected to be busier than usual.
"We're going to see more vehicles and it concerns me greatly," he said.
Superintendent Stewart asked people to drive to the conditions, avoid distractions, wear seatbelts and to avoid taking risks behind the wheel.
Police will continue to investigate the crash and are urging anyone with information to come forward.
