A man has been charged after he was detected by officers driving at 124mph in a 60mph zone on the A68.
Police stopped the man in a Renault Megane Sport car at around 3.20pm on Saturday near to Cousland junction in Midlothian.
Trunk Roads Policing Inspector Roddy MacMillan said: “Motorists and other road users should be mindful that our Vulnerable Road Users Campaign is currently running.
“Excessive or inappropriate speed is one of the main contributors to serious injury and fatal road collisions and such neglegent driving behaviour will not be tolerated.
“We will be using marked and unmarked cars and motorcycles to engage, educate and enforce. Our aim is to encourage and promote safety on our roads in an effort to reduce collisions and resultant casualties.
“I would encourage anyone who does witness unsafe motoring activity to contact Police Scotland on 101, or anonymously through Crimestoppers on 0800 555 111”.
