(1) No statutory provision imposing a speed limit on motor vehicles shall apply to any vehicle on an occasion when it is being used for fire and rescue authority, for ambulance purposes or police purposes, if the observance of that provision would be likely to hinder the use of the vehicle for the purpose for which it is being used on that occasion.
(1A) Subsection (1) above applies in relation to a vehicle that, although not being used for ambulance purposes, is being used for the purpose of providing a response to an emergency at the request of an NHS ambulance service.
(1B) In subsection (1A), “an NHS ambulance service” means—
(a) an NHS trust or NHS foundation trust established under the National Health Service Act 2006 which has a function of providing ambulance services;
(b) an NHS trust established under the National Health Service (Wales) Act 2006 which has a function of providing ambulance services;
(c) the Scottish Ambulance Service Board.
(2) Subsection (1) above applies in relation to a vehicle being used—
(a) for National Crime Agency purposes, or
(b) for training persons to drive vehicles for use for National Crime Agency purposes,
as it applies in relation to a vehicle being used for police purposes.
(3) But (except where it is being used for training the person by whom it is being driven) subsection (1) above does not apply in relation to a vehicle by virtue of subsection (2) above unless it is being driven by a person who has been trained in driving vehicles at high speeds.
