Britain's Special Forces have been given the same exemption from the road laws as the emergency services in order for them to get to terror incidents as quickly as possible.
The SAS maintains a constant presence in the UK to respond to a terrorist attack, but it had previously lacked any legal right to exceed the speed limit - even in the name of national security.
The order handed down by ministers on the Cobra committee means that troops will now be free to break the speed limit, ignore road markings and disregard traffic signals when answering a call.
The Sun newspaper reported that the Department for Transport had 'quietly' introduced the required exemption in a new law presented to Parliament.
Transport Minister Mike Penning said: "It makes sense to give Special Forces the same exemptions that the police already have. They only apply for national security purposes.
