DYFED-POWYS Police has put out an appeal to motorists not to form unnecessary queues at petrol stations.

The force has reported "a very small number of temporary interruptions" but advise that there is "no cause for concern."

It follows national reports of a tanker driver shortage causing delivery problems, which led to a surge in demand at the pumps.

There were reports of some key workers in the region struggling to get the fuel they needed to travel to their work.

But while some stations have seen queues and closed forecourts, others have seen motorists able to fill up as normal.

"Jointly, partner agencies in the Dyfed-Powys region are thanking the vast majority of motorists in the area who are purchasing fuel responsibly and calmly," read a statement.

"We are in touch with fuel stations, who have confirmed there is no disruption to deliveries at most sites, and there is more than adequate fuel stocks across the area.

"Although we have seen a very small number of temporary interruptions in isolated areas. But certainly no cause for concern.

"Please continue to show restraint and normal purchasing of fuel, and do not form queues which can cause unnecessary obstructions on roads for road users and pedestrians."

Addressing concerns over the scenes on forecourts across Wales, finance minister Rebecca Evans urged drivers to act responsibly when filling up.

“I understand people's anxieties having seen the situation in terms of the queues and petrol stations that have run out of petrol," she said.

“The most important thing to recognise is there is plenty of fuel here. There’s plenty of fuel at the refineries; there’s plenty of fuel in storage as well.

“What we do have is a problem in terms of the logistics, and I know that there is work ongoing at the moment to sort that."

“We all have to behave responsibly. I know it can be stressful and worrying for people but we have to remember there are people who work in critical sectors who do need that petrol.

“We do have a National Fuel Plan which could prioritise certain individuals or groups for the access to fuel.

"But we haven’t invoked yet because we understand the system will get itself back into kilter very shortly.”

Ms Evans said the Welsh Government were in continued discussions with the UK Government and local resilience forums about the issue.

“At the moment there is plenty of fuel and we just need to act responsibly in accessing what we need,” she said.

“I think we can be reasonably confident that the situation will come back into kilter in terms of supply and demand fairly shortly.

“There is no reason for people to panic, there is plenty in the system if we are all responsible.”

Meanwhile, the Petrol Retailers Association (PRA), which represents 5,500 out of the UK's 8,000 filling stations, said there were "early signs" the crisis was ending.

"Fuel stocks remain normal at refineries and terminals, although deliveries have been reduced due to the shortage of HGV drivers," said PRA executive director Gordon Balmer.

"We have conducted a survey of our members this morning and only 37% of forecourts have reported being out of fuel today.

"With regular restocks taking place, this percentage is likely to improve further over the next 24 hours".
