did_you_know782Question:

Good day I have had a request from relatives living in the UK for the maximum width trailer allowed on our roads towed by a Bakkie. I think that if you are able to supply this information they would probably require the distance also from ball to axle and also length from axle to rear no plate (overhang). Thanking you in anticipation.

Answer:

Overall length (Regulation 221) I assume the highlighted section applies

No person shall operate on a public road—

(a) a trailer which is coupled to a drawing vehicle in such a manner that the trailer and the drawing vehicle cannot swivel in a horizontal plane at the coupling, if the overall length including any drawbar or coupling exceeds one comma eight metres;

(b)a trailer with one axle or one axle unit, other than a semi-trailer—

(i)the gross vehicle mass of which exceeds 12 000 kilograms, if the overall length of such trailer, excluding any drawbar or coupling, exceeds 11,3 metres; or

(ii)the gross vehicle mass of which does not exceed 12 000 kilograms, if the overall length of such trailer, excluding any drawbar or coupling, exceeds eight metres;

(c)a trailer not referred to in paragraph (b), excluding a semi-trailer, the gross vehicle mass of which exceeds 12 000 kilograms, if the overall length of such trailer, excluding any drawbar or coupling, exceeds 12,5 metres;

Overall width regulation 223

No person shall operate on a public road—

(a)a bus of which the distance between the centre-lines of the tyres of the two front wheels exceeds one comma nine metres, if the overall width of such bus exceeds two comma six metres;

(b)a goods vehicle the gross vehicle mass of which is 12 000 kilograms or more, if the overall width thereof exceeds two comma six metres; or

(c)any other vehicle, if the overall width thereof exceeds two and a half metres.

Rear overhang – Regulation 226

(1)  No person shall operate on a public road—

(a)a semi-trailer, the front overhang of which exceeds one comma eight metres; or

(b)a vehicle, other than a semi-trailer or a trailer with one axle or one axle unit, the front overhang of which exceeds—

(i)60 percent of the wheelbase;

(ii)six comma two metres in the case of a vehicle having the front surface of the back rest of the driving seat at seat level not more than one comma seven metres from the front end of the vehicle when such seat, if adjustable, is in the rearmost position, less half the wheelbase: Provided that the wheel-base of a bus-train shall be the distance measured from the centre of the front axle to the centre of the middle axle; or

(iii)five comma eight metres in the case of any other vehicle, less half the wheelbase.

(2)  No person shall operate on a public road—

(a)a vehicle designed or adapted for use in connection with street cleaning or the disposal of refuse or sewage, or any vehicle referred to in regulations 220, 230 or 249, or any bus, or motor home the rear overhang of which exceeds 70 percent of its wheel base;

(b)a trailer, other than a semi-trailer, which is equipped with—

(i)one axle;

(ii)one axle unit; or

(iii)two axles, the distance between the centre-lines of which is less than one comma two metres,

if the rear overhang exceeds 50 percent of the length of the body of such trailer; or

(c)any vehicle, not referred to in paragraph (a) or (b), the rear overhang of which exceeds 60 percent of its wheelbase.

    Hi,

    What is the legal height and weight requirement for a 1 tonne bakkie and a 7m flat bed trailer transporting mattress and does the flat bed trailer need to be fitted with a air brake system
