Traffic officers from the West Midlands police prevented a serious collision on the M6 toll after a car was traveling the wrong way on the northbound carriageway Monday night.
The footage shows a Honda Jazz coming down the motorway at speed, before officers positioned their vehicle to prevent it reaching the oncoming traffic and force it into the central reservation.
The driver was a 77-year-old man, who has dementia who had been reported missing from his home in Rowley Regis earlier that evening.
He was not injured during the incident, and after being checked over by paramedics, was taken home to his family.
Force Traffic Manager, Inspector Greg Jennings said: "Traffic officers are highly trained to make good decisions in difficult situations and a very challenging environment. These officers have kept their resolve in the face of a serious threat to ensure the safety of the public directly behind them.
"Thankfully the officers managed to stop the vehicle with only minor injury to one of them.
"The family of the Honda driver have thanked us for bringing the incident to a safe conclusion."
