Officers in MI5 and MI6 currently have to abide by the rules of the road – even when national security is under threat.
But transport minister Robert Goodwill is to hand them the same exemptions as police, fire and ambulance drivers.
They will be able to break the speed limit once they have completed a training course in high-speed driving accredited by the Driving Standards Agency.
Other groups also likely to be permitted to legally break the speed limit include vehicles carrying transplant organs, bomb disposal units, mountain rescue teams and those engaged in ‘surveillance and covert operations’.
More than 90 per cent of people who responded to the consultation backed extending speed limit exemptions to those involved in ‘the protection of life and limb or national security’
