Dyfed Powys Police are cracking down on foreign lorry drivers who try to evade the law.
In Pembrokeshire, officers are trialling a graduated fixed penalty scheme for traffic offences.
The scheme can be applied to anyone who doesn’t have a permanent UK address at the time of the offence.
Chief Inspector Steve Matchett said: “In the past foreign drivers have been stopped but prosecutions through the court have proved difficult because the offender cannot be traced.
“This scheme allows us to ensure the driver pays a deposit on the road side or they vehicle is prohibited.
“This has resulted in lorry drivers and their companies getting a clear message that they ensure their vehicles are safe and their drivers are legal before coming on our roads.”
Since July 1 in Pembrokeshire 53 graduated fixed penalty notices were issued to a value of over £8,000.
If the scheme proves successful it will be extended to other areas of the force.
