Road Traffic Act 1988

7 Provision of specimens for analysis

(1) In the course of an investigation into whether a person has committed an offence under section 4 or 5 of this Act a constable may, subject to the following provisions of this section and section 9 of this Act, require him—

(a) to provide two specimens of breath for analysis by means of a device of a type approved by the Secretary of State, or

(b) to provide a specimen of blood or urine for a laboratory test.

(2) A requirement under this section to provide specimens of breath can only be made at a police station.

(3) A requirement under this section to provide a specimen of blood or urine can only be made at a police station or at a hospital; and it cannot be made at a police station unless—

(a) the constable making the requirement has reasonable cause to believe that for medical reasons a specimen of breath cannot be provided or should not be required, or

(b) at the time the requirement is made a device or a reliable device of the type mentioned in subsection (1)(a) above is not available at the police station or it is then for any other reason not practicable to use such a device there, or

(c) the suspected offence is one under section 4 of this Act and the constable making the requirement has been advised by a medical practitioner that the condition of the person required to provide the specimen might be due to some drug;

but may then be made notwithstanding that the person required to provide the specimen has already provided or been required to provide two specimens of breath.

(4) If the provision of a specimen other than a specimen of breath may be required in pursuance of this section the question whether it is to be a specimen of blood or a specimen of urine shall be decided by the constable making the requirement, but if a medical practitioner is of the opinion that for medical reasons a specimen of blood cannot or should not be taken the specimen shall be a specimen of urine.

(5) A specimen of urine shall be provided within one hour of the requirement for its provision being made and after the provision of a previous specimen of urine.

(6) A person who, without reasonable excuse, fails to provide a specimen when required to do so in pursuance of this section is guilty of an offence.

(7) A constable must, on requiring any person to provide a specimen in pursuance of this section, warn him that a failure to provide it may render him liable to prosecution.
