How will transport be affected

The impacts of a no deal are significant and will impact every region and nation of the UK. It could cause severe disruption to the transport network and connected services within Wales.

We are taking all proportionate steps to preserve the integrity of our transport system in the face of a no deal Brexit and ensure the continued viability and success of our transportation system.



In the event of no deal, drivers from the UK will need extra documentation to drive in the EU and EEA. UK driving licences will continue to be recognised, but parties to this agreement may require holders to have an international driving permit if they are driving on the continent in future.

This includes registering certain trailers with the Driver and Vehicle Licensing Agency (DVLA) and carrying a trailer registration certificate.

In the event that the UK leaves the EU without a deal, UK drivers may also need an international driving permit (IDP) to drive in the EU and EEA.

In respect of motor insurance, EU law allows any vehicles insured in one member state to be driven in any other. However, vehicles normally based in a third country – which the UK will be after a no deal Brexit – need to have a valid "green card” to be covered.

While the UK participates in this system, it will mean additional bureaucracy for drivers wanting to drive in and to EU, who will have to carry motor insurance green cards to prove they have valid insurance.


Ports would be particularly vulnerable in a no deal Brexit situation.

Ports in Wales make a critical contribution to our economy, not least by providing jobs and added value to our local communities. Any risk to their efficient operation poses a substantial risk for Wales as a whole. Most of the risks relate to border arrangements – to customs and safety checks. The UK government must make assurances that all steps will be taken to mitigate these risks.

We are working closely with port operators, ferry operators, local authorities and the UK government. Following these discussions, the UK government has taken the decision to make no additional checks on goods coming through roll-on roll-off ports from EU countries in a no-deal scenario in the short-term.

The Welsh Government are working to mitigate other potential impacts on trade in Wales, including a range of options for managing potential traffic disruption involving freight vehicles at Welsh ports, particularly Holyhead as the second busiest roll-on roll-off port in the UK, after Dover.

An assessment of the reasonable worst case scenario for Heavy Goods Vehicle delays has been prepared by the UK government, and this applies to all ferry ports across the UK. This assessment is underpinned by a number of cross-government and cross-departmental assumptions, such as the checks that might be imposed and what infrastructure could be in place.

The modelling indicates that it is likely that delayed traffic at Holyhead could be held within the confines of the port and any overflow on the A55 would be unlikely.

However, the modelling is based on a range of common assumptions about which there remain a significant number of uncertainties and which are being constantly reviewed. We are therefore developing contingency plans as part of the Holyhead Port Strategic Consultation Group which was set up last year.

Potential sites on Anglesey have been identified and assessed, including the existing Roadking truck stop facility which is geographically well-placed, has no developmental issues and has suitable infrastructure already in place. We are discussing details with Roadking.

Parc Cybi is another option – this is a Welsh Government development site and has sufficient capacity for 40 HGVs. As a further fall back option the A55 could be used. Across Anglesey, road works are carried out with day-time lane closures and minimal disruption. Similar measures could be used, in the unlikely event they were necessary, and to manage freight delays at the port.

Plans to minimise Holyhead Port no deal disruption

These plans will only come into force in the event of a no deal exit. If a deal is reached between the UK government and the European Union and an orderly exit can be achieved, these plans will not be required.

In the event of a no deal, goods from the UK will be treated as being from a “third country” as they enter the EU and will be subject to additional checks in Ireland, potentially causing delays to ferries and a backlog in Holyhead.

The Welsh Government has been working with partners over recent months to ensure that any disruption to the port in the event of a no deal Brexit is kept to a minimum. But there is a risk of some disruption to the normal free flow of goods.

The plans will ensure HGVs can be safely stacked and allow local people and businesses to continue their daily lives with as little inconvenience as possible. They will also ensure lorry drivers have a safe, welcoming and secure place to go to, with available facilities.

Analysis by the Department of Transport suggests the likelihood of HGVs overflowing into the surrounding areas from the port is likely to be minimal because of the capacity of existing facilities within Holyhead Port. But contingency plans have been put together in the event of longer delays developing.

Holyhead Port can accommodate 660 HGVs; the plan will provide additional space to accommodate more if required. HGVs will be directed to the existing Roadking services at Parc Cybi, close to the port’s entrance, where 175 HGVs can be accommodated, with welfare facilities for drivers.

The Welsh Government has arranged for free parking for Dublin-bound freight traffic at the site under these arrangements and traffic management will be in place to direct HGVs seamlessly to the site. Additional traffic officers will be on hand to help around the clock.

Road space around Parc Cybi will also be used if necessary, with space for a further 30 stacked HGVs.  In the unlikely event of all these spaces not being sufficient, further contingency measures have been developed – HGVs will use the westbound carriageway of the A55 at Holyhead (junctions 2 to 3). This is the quietest section of the A55 and the impact on the travelling public is expected to be minimal.

In respect of Pembroke Dock and Fishguard, Wales’ other ferry ports, analysis indicates that delayed vehicles resulting from hold-ups at Rosslare could be held and managed within the port environs and any increased congestion on public roads would not be significant. Therefore there would be no need for additional contingency arrangements. However the assumptions underpinning the analysis are again finely balanced and are being kept under constant review in order to react quickly if necessary in putting in place any additional contingency measures and support the smoothest possible flow of goods between Welsh ports and Ireland.

Container ports, such as Cardiff, Port Talbot and Newport, are already engaged with international goods movement and are less likely to experience significant disruption.

Air services

The EU has proposed regulations to continue existing direct flights between the EU and the UK until 30th March 2020 or sooner if a deal is agreed. UK operators could lose the ability to operate flights to the EU on to another destination, whether within Europe or otherwise.

This could have important and negative implications for business and leisure travellers from Wales and the UK regardless of where they travel from.

Cardiff airport is prepared for all eventualities, and it will continue to serve customers by offering an enjoyable, efficient customer service and diverse route network. It will continue to support airline partners, work with agencies including the Department for Transport, UK Border Force and the Welsh Government to seek out new opportunities to grow the airport business throughout this period of uncertainty.

In terms of the impact of a no deal Brexit on Cardiff Airport, it is unlikely to have a significant impact on day one and in the short term. It is difficult to fully understand the longer term impact until new agreements are in place.

Customers will see changes to Duty Free when travelling outbound and changes to signage when arriving back to the UK border.  Those travelling from the UK into Europe must ensure they have followed the latest government advice before travelling: Visit Europe after Brexit on GOV.UK.

Travelling with your pet

If you want to take your pet abroad, additional health requirements and documentation will be needed in the event of a no deal Brexit. These preparations will need to be discussed with your vet at least four months before you travel. Extra requirements include:

  • a blood test and vaccine against rabies
  • a health certificate

Freight haulage

An information campaign is being launched across the UK and Europe to ensure businesses and hauliers are prepared for the UK to leave the EU. The public awareness drive will make sure hauliers obtain everything they need from traders to get through border customs smoothly, reducing risk of delays at ports. As part of the campaign an email will be sent to 70,000 UK operators, industry bodies and other interested parties detailing essential information for those driving to the EU after 31 October. If the UK leaves the EU without a deal, hauliers will be required to go through customs checks when exporting goods to the EU from the UK. It is the responsibility of traders to apply and obtain the right paperwork for the goods hauliers are carrying. The UK government will also be providing hauliers with a handbook and a pocket guide to clearly set out how they can prepare themselves, their vehicles and their goods so that they can continue to travel freely. The how-to guides will be available across the UK and the continent at pop-up facilities in service stations, truck stops and petrol stations.

Transport for Wales

In the event of a no-deal Brexit scenario, our Transport for Wales (TfW) network has plans in place to operate as normal on day one, with a number of plans already in place to minimise potential impacts. Similarly, we are working closely with other partners, such as ferry ports and other public services to ensure any potential impact is minimised as far as possible. We are participating fully in all relevant government planning and coordination activities to ensure we are fully prepared.

Like many employers, we are considering the impact on our people for a potential no-deal Brexit scenario, and whilst the vast majority of current TfW employees and supplier employees are UK residents, we are still working to reassure the employees who are not UK-based, who may be affected by potential changes.

We are working closely with our supply chain to understand the potential impact on the import of parts and particularly how this may affect the maintenance of our trains. While the majority of our current fleet originate from the UK and therefore require minimal import of parts, elements of our fleet do require parts from Europe and our preparation plans look to minimise the impact of any delay in this current process. Aside from rolling stock, some other suppliers do source from Europe and we are working to minimise the impact of changes to the import process for these smaller, yet important suppliers.

Collaboration with Ferry Operators

Transport for Wales already have arrangements in place to ensure that the impact on passengers as a result of disruption to ferry services is minimised as much as possible. If passengers miss ferry connections as a result of rail disruption, we will arrange suitable alternative arrangements, including potential overnight accommodation and appropriate welfare facilities. Where ferry disruption is notified via our established processes, we work with ferry operators to provide information to rail passengers both prior to and during rail journeys, via multiple channels, including online platforms, on train announcements and via station staff.

Where enough prior notice is provided, we will advise rail passengers not to travel, which will provide them opportunity to book alternative arrangements with the ferry operators. Where ferry crossings are disrupted and train connections are missed, we will work collaboratively with ferry operators to ensure that onward travel arrangements for which they are responsible for organising, connect with alternative rail services at locations such as Swansea and Holyhead.
