Legislation

Road traffic legislation for vehicles in use on Irish roads and type approval legislation for new vehicles. 

This content is for general information only. It does not, and is not intended to, provide legal or technical advice or to represent a legal interpretation of the matters it addresses.

Vehicles in-use legislation

All vehicles and trailers on Irish roads must conform to a minimum standard of construction. This applies to all of their parts as well, such as seat belts, lights, tyres, glass and so on. Applying minimum standards helps ensure that vehicles are safe to drive, safe for passengers and safe for other road users.

If you’re the owner, operator or driver of a vehicle or combination of vehicles such as a truck and trailer, it’s your legal responsibility to ensure that your vehicle is safe and roadworthy when used in public places. Driving a dangerously defective vehicle can result in a fine of up to €5,000 and/or imprisonment of up to three months.


Three primary pieces of road traffic legislation

Road Traffic Construction, Equipment and Use of Vehicles Regulations (as amended). 

S.I. 190 of 1963 (as amended) sets out the requirements for the construction, equipment and use of vehicles (including large public service vehicles and small public service vehicles) being used on public roads. They also set out how different types of vehicles and equipment should be used and the legal responsibilities of drivers and passengers.

Road Traffic Construction and Use of Vehicles Regulations (as amended) 

S.I. 5 of 2003 (as amended) sets out the permitted weights and dimensions of vehicles and their trailers when used on Irish roads.

Road Traffic (Lighting of Vehicles Regulations (as amended)

S.I. 189 of 1963 sets out the rules for lights fitted to vehicles being used in public places, and rules on how those lights should be used.

Note: the above regulations are the original documents. Over time amendments are made to the legislation to keep up with changing legislation, behaviours, enforcement, technology, government strategy and so on.

Type approval legislation

Type approval helps remove barriers to trade for manufacturers and ensures that new vehicles are manufactured to prescribed safety and environmental standards.

Vehicle safety is critical. Vehicle manufacturers, the EU and each Member State have many regulations, tests and controls in place to maximise safety at every stage of a vehicle's life from manufacture to registration to road use. These all relate to the process of type-approval.

Frequently Asked Questions

Type approval laws for cars

When a car is first manufactured it must pass all the necessary safety and quality standards before it can be sold or registered throughout Europe – this is known as European type approval. Since 29 April 2009 all newly manufactured vehicles must be type approved.

The national standards authority of Ireland (NSAI) is the appointed approval authority in Ireland responsible for issuing all national approvals for brand new unregistered vehicles only e.g., IVA or NSSTA.

This relates to new unregistered passenger cars imported or manufactured in very small numbers or as individual vehicles. Each car is checked and on passing inspection at an NSAI appointed test centre an IVA cert is issued to allow registration in Ireland.

This is certification for small batches of cars up to a maximum of 250 intended for Irish or national use. When NSSTA is granted the manufacturer can issue a CoC for each vehicle of same type.

This is certification issued to manufacturers of large quantities of the same type of car. Instead of having to obtain approval for each and every identical car one model or prototype is used. If that one car is approved, then certification will be issued to all cars of the same model which means they can be sold or registered throughout Europe.

No. Under EU law, mutual recognition of national approval schemes is only permissible between EU Member States.

Revenue will not register a new vehicle unless it has a valid certificate of conformity (CoC).

A CoC is issued to the manufacturer as proof that the car achieved type approval and can be sold and registered throughout European member states.

For a car to be type approved and obtain its CoC every vehicle must be identical to the car originally approved. This is known as CoP. There are no conformity of production requirements for individual vehicle approval.

You will need to contact the original manufacturer.

CoC can only be obtained from the vehicle manufacturer in the country where the vehicle was first registered.

Type approval laws for light trailers (01 and 02)

When a trailer is first manufactured it must pass all the necessary safety and quality standards before it can be sold or registered throughout European member states, this is known as European type approval. Since 29 October 2012 all newly manufactured trailers must be type approved.

It is a trailer which has the following EU categories.

O1 – Trailer with a Design Gross Vehicle Weight (DGVW)* of 750 kg or less

O2 - Trailer with a Design Gross Vehicle Weight (DGVW)* over 750 kg but not exceeding 3,500 kg

*DGVW or maximum authorised mass (MAM) is the weight of a vehicle or trailer including the maximum load it can carry as per the manufacturer’s design specifications.

The national standards authority of Ireland ( NSAI) is the appointed approval authority in Ireland responsible for issuing all national approvals e.g., IVA or NSSTA for brand new unregistered vehicles only.

This relates to an individual vehicle or trailer. Each trailer is checked and on passing inspection at an NSAI appointed test centre (ATC) an IVA cert is issued.

This is certification for small batches of trailers to a maximum of 500, intended for Irish or national use. When NSSTA is granted the manufacturer can issue a CoC for each trailer of same type.

This certification is issued to manufacturers of large quantities of the same type of trailer. Instead of having to obtain approval for each and every trailer one model or prototype is used. If that one trailer is approved, then a certificate of conformity (CoC) will be issued to all trailers of the same type.

This is issued to the manufacturer as proof that the trailer achieved type approval and can be sold throughout European member states.

For new trailers contact the original manufacturer.

To obtain type approval for brand new trailers contact the NSAI.

No. Under EU law, mutual recognition of national approval schemes is only permissible between EU Member States.

Any new trailer built since 29 October 2012 must be type approved and have a CoC. This ensures that the design, lighting, braking etc. has met a European safety and quality standard.
