A five-vehicle smash on a busy Perthshire motorway saw one person rushed to hospital when a car collided with four other vehicles on Wednesday afternoon.
Police believe the driver of the car may have been driving the wrong way down the M90 near Bridge of Earn when it hit the four other vehicles, including a HGV lorry, at around 2pm.
A spokesperson for Police Scotland said they were “pursuing a line of enquiry” that the driver of the vehicle had turned the wrong way onto the motorway after exiting a slip road.
Paramedics and firefighters also worked the scene of the crash between junctions nine and 10, with one person having to be cut from their car.
A spokesperson for Scottish Fire and Rescue Service said: “We had to remove one person from one of the vehicles but the rest managed to get out themselves.”
An eyewitness to the incident described the terrifying moment he saw the car turn into oncoming traffic – narrowly missing his own vehicle by a few feet.
Driver Wattie Garland, 51, said: “I was coming up from Dunfermline towards Perth and I saw cars braking in front of me on the slip road.
“I was overtaking a lorry and I saw a car — I’m not sure what type — with a male driver in it and he was just coming the wrong way down towards the motorway.
“A lorry behind me swerved out and I just saw dust and cars in the hard shoulder in my mirror.
“I think the car might have gone into the side of the lorry.”
He added: “He was going about 30-40mph but the guy’s face was total fear.
“He’d obviously realised he’d made a mistake, rather than anything deliberate.
“I’m just in a bit of shock because it was so close to me being involved in it.
“I just hope everyone is OK.”
Wattie is a trained first-aider and said he is frustrated he could not help at the scene.
He said: “There was no way I could stop because I was already past it.
Wattie, who lives in St Madoes, said conditions were good and there was no obvious reason why the driver was heading the wrong way.
The northbound lane of the motorway was closed for nearly two hours following the collision causing long traffic queues on both M90 and through Bridge of Earn where diversions were put in place.
