"14. (1) If the traffic authority for a road are satisfied that traffic on the road should be restricted or prohibited -- (a) because works are being or are proposed to be executed on or near the road; or (b) because of the likelihood of danger to the public, or of serious damage to the road, which is not attributable to such works . . . . the authority may by order restrict or prohibit temporarily the use of that road, or of any part of it, by vehicles, or vehicles of any class, or by pedestrians to such extent and subject to such conditions or exceptions as they may consider necessary."
"The provision that may be made by an order or notice under the foregoing provisions is . . . (b) any provision restricting the speed of vehicles . . . "
"89. (1) A person who drives a motor vehicle on a road at a speed exceeding a limit imposed by or under any enactment to which this section applies shall be guilty of an offence. (2) A person prosecuted for such an offence shall not be liable to be convicted solely on the evidence of one witness to the effect that, in the opinion of the witness, the person prosecuted was driving the vehicle at the speed exceeding a specified limit. (3) The enactments to which this section applies are -- (a) any enactment contained in this Act except section 17(2) . . . "
"16. (1) A person who contravenes, or who uses or permits the use of a vehicle in contravention of, a restriction or prohibition imposed under section 14 of this Act shall be guilty of an offence."
"12. (1) Subject to the provisions of this section, if a highway authority are satisfied that traffic on a road should, by reason of any works being executed or proposed to be executed on or near the road, be restricted or prohibited, they may by order restrict or prohibit the use of that road ..."
"A person who uses or permits the use of a vehicle in contravention of a restriction or prohibition imposed under this section shall be liable on summary conviction to a fine not exceeding£20 ."
"The offence of using or permitting the use of a vehicle in breach of a temporary speed restriction imposed under [the 1967 Act] section 12, is not subject to the maximum penalty provided by [the 1967 Act], section 78A, for exceeding a general speed limit (namely, a fine of£100 and compulsory endorsement)."
"The appellant appealed on the ground that the maximum penalty for the offence was that provided byRoad Traffic Regulation Act 1967, section 78A , namely a fine of£100 and mandatory endorsement."
"The offence of driving in excess of a temporary speed restriction was not the same as driving at a speed in excess of the general speed limit, and the maximum penalties for that offence did not apply to driving in excess of a temporary speed limit."
"It is equally obvious that a person may so excessively exceed the temporary restriction as to exceed also the relevant general speed limit. In such a situation he will have committed two offences . . . "
"No statutory provisions imposing a speed limit on motor vehicles shall apply to any vehicle on an occasion when it is being used by for fire and rescue authority, ambulance 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."
"(1) Was the court wrong in law to rule that no prosecution can lie undersection 89 of the Road Traffic Act 1984 for exceeding -- (i) a temporary speed limit; and/or (ii) a temporary speed restriction imposed by an order under section 14(1) of the same Act? (2) Was it wrong in law to rule that the court was bound by the decision of the High Court in the case of Platten v Gowing to rule that no prosecution can lie undersection 89 of the Road Traffic Regulation Act 1984 for exceeding -- (i) a temporary speed limit; and/or (ii) a temporary speed restriction imposed under section 14(1) of the same Act?"
