# The Road Vehicles (Construction and Use) (Amendment) (No. 3) Regulations 1990, Note: Explanatory note


(This note is not part of the Regulations)
1 These Regulations further amendthe Road Vehicles (Constructionand Use) Regulations 1986.
2 Under the 1986 Regulations as originally enacted, an articulated vehicle was subject to an overall lengthrestriction of 155 metres. As a result of S.I. 1990/317 such a vehicle could have an overall lengthof 165 metres if it met certain requirements. One of those requirements was that the longitudinal distance from the axis of the king-pin, or if there was more than one king-pin the foremost one, to the rear of the semi-trailer did not exceed 125 metres in the case of a car transporter or 12 metres in any other case. Another requirement was that the distance of any point on the front of the trailer from the king-pin, or if there was more than one king-pin the rearmost one, did not exceed 419 metres in the case of a car transporter or 204 metres in any other case. These regulations amend the 1986 Regulations so that the measurement is taken from the rearmost king-pin if there is more than one king-pin or the rearmost king-pin position if a king-pin can be fixed in different positions.
3 The 1986 Regulations as amended by S.I. 1990/317 imposed an overall lengthon an articulated vehicle, the semi-trailer of which is a low loader, of 18 metres. The Regulations are amended so that this provision does not apply to a low loader manufactured before1st April 1991.
4 The 1986 regulations as amended by S.I. 1990/317 impose turning circle requirements on articulated vehicles having an overall length exceeding 155 metres. An exception was made for articulated vehicles, the semi-trailer of which was manufactured before the 1st April 1990 and on that date had an overall lengthexceeding 122 metres providing the overall lengthdid not exceed the overall length it had on that date. As a result of the amendments made by these Regulations the exception applies in all cases wherea semi-trailer was manufactured before 1st April 1990 (whether its length exceeds 122 metres or not) provided its overall lengthis no greater than it was on that date.The amendment has no effect on the turning circle requirements relating to car transporters.
