A fail to remain collision that injured two people is being investigated by South Bruce OPP.
Police say Sunday around 1:15 PM, they arrived to the collision scene on Bruce Road 3 and Concession Road 14 just south of Paisley.
They found a car had crashed in the ditch.
The 49 year old driver from Kitchener and his 45 year old passenger from Milton both had minor injuries.
The driver says he was travelling south when a northbound vehicle crossed over to the southbound side of the highway.
To avoid a head-on collision he swerved and the northbound vehicle did slow down, but kept driving.
The suspect vehicle is described as dark coloured, possibly a Pontiac Grand Prix — or something similar.
Investigators would like to speak with any witnesses and those with information are urged to call South Bruce OPP (1-888-310-1122).
