Ukrainian arrivals will be allowed to exchange their driving licence for an Irish one, the Minister for Transport Eamon Ryan has said.
This will "make it easier for them to move around and access work, school or other vital public services".
Minister Ryan said he had signed an order today that will allow Ukrainians temporarily resident (under the Temporary Protection Directive) in Ireland because of the conflict to drive their cars here if they exchange their Ukrainian driving licence for an Irish licence.
He added: "It operates much like renting a car if we are in another country, for example, and comes with the same warnings that users must be acutely aware of the rules of the road in that country.
"I strongly urge anyone applying for an Irish licence to take time to familiarise themselves with the Irish road system."
The new licence will be valid for 12 months and will apply to cars only.
Minister of State Hildegarde Naughton added: "Today's announcement is very important for individuals and families who have fled the war as it will allow them move around and access employment opportunities and vital public services including education and healthcare while they are living in Ireland.
"It is vital that motorists are aware of the changes that come with driving in another country in order to protect themselves, their families and other road users. Information which will be provided by the Road Safety Authority will be very helpful in this regard."
Sam Waide, CEO of the RSA said it will provide information in Ukrainian on its website.
"The RSA will have a presence at ferry ports to provide information to Ukrainian refugees arriving by car and we are making arrangements to provide information for all refugees already in the country.
"The National Driver Licence Service, which is operated on behalf of the RSA, is also geared up to accept applications for licence exchange from Ukrainian refugees."
