The pictures were released in the hope of achieving a breakthrough in the investigation, which has now entered its fourth week.
Mrs Methven, 80, was battered to death in the kitchen of her cottage in Forteviot, Perthshire, on Monday, 20 February.
She was found slumped at her kitchen table with a bloodstained towel over her head by her son David, 57. Her son, who shared the two-bedroom cottage with his mother, is not a suspect in the investigation.
A spokesman for Tayside Police said the images of the five vehicles were being released in the hope that the occupants could provide “valuable” information.
The force spokesman said: “All of the vehicles were seen between 10am and 11am in the area between Bridge of Earn and Dunning. The inquiry team want to hear from the drivers and any occupants, as they were in the area at a time when they may have seen something that could prove to be valuable to the investigation.”
One of the vehicles is an articulated lorry with a white cab and red side curtain travelling west towards Dunning.
The second vehicle is a silver car heading towards Dunning.
The third image shows a black vehicle travelling behind a tractor and trailer heading towards Forteviot from Bridge of Earn.
The fourth vehicle is a red Scania cab with log trailer coming from Bridge of Earn towards Forgandenny.
The final image is of a silver hatchback car which travelled behind a bus from the Forgandenny/Forteviot direction to Bridge of Earn on the day of the murder.
