Foreign-registered vehicles using the M50 are subject to the same rules as Irish-registered vehicles.
For all motorists using the M50, whether registered or unregistered, national or foreign, the non-payment of tolls is an offence under the legislation. The Transport Infrastructure Ireland (formerly known as the National Roads Authority) has therefore established a rigorous enforcement policy implemented through a trans-European enforcement agency to assist in the recovery of unpaid toll charges and fines and the prosecution of all toll evaders of Irish or foreign registered vehicles.
The onus is also on foreign motorists arriving in any country to be aware of bye-laws and rules of the road. Information is also available through motoring organisations, car hire companies and tourist bodies here and abroad.
