EXPLANATORY NOTE

(This note is not part of the Instrument and does not purport to be a legal interpretation.)

These Regulations come into force on 1 February 2018.

These Regulations amend the Road Traffic (Construction and Use of Vehicles) Regulations 2003 ( S.I. No. 5 of 2003 ) to:

• impose a maximum weight limit for rigid vehicles (other than agricultural tractors, agricultural trailers and vehicles that are subject to a special permit) that have more than four axles;

• require that, in the event of any modification being made to the number of axles of a rigid vehicle (other than an agricultural tractor, an agricultural trailer and a vehicle that is subject to a special permit) so that the vehicle, post-modification, has more than four axles, the maximum weight laden of the relevant vehicle must be re-assessed and a declaration of conformity in respect of it must be prepared (by the manufacturer, the authorised distributor or an appointed person);

• require that a vehicle to which these Regulations apply must, when used in a public place, be fitted with a manufacturer’s plate or an authorisation plate that displays in permanent form specified information from the certificate of conformity (or, as appropriate, the declaration of conformity) in respect of the maximum weight laden and individual axle limits of that vehicle; and

• in the case of a triaxle, subject to an overall weight limit of 21 tonnes (if the distance between the two closest adjacent axles is less than 1.3 metres) or 24 tonnes (if the distance between the two closest adjacent axles is at least 1.3 metres), impose a limit of 9.5 tonnes per driving axle, where specified conditions are met.

The maximum weight laden of a rigid vehicle:

(a) that is first registered in the State on or after 1 February 2018 and which at the time of that first registration has more than four axles, or

(b) which, on or after 1 February 2018, is modified so that, post-modification, the vehicle has more than four axles,

is the lower of:

(i) 36 tonnes, and

(ii) the design weights specified (by the manufacturer or authorised distributor of the vehicle or an “appointed person” only) on the vehicle’s certificate of conformity or completed declaration of conformity.

Further, the weight laden (expressed in tonnes) of a vehicle to which these Regulations apply must not exceed the number that is obtained when the distance between the extreme front and rear axles, expressed in metres correct to two decimal places, is multiplied by 5.5.
