Do You Need a Car in Dublin?
For the city itself — no. Dublin's public transport (LUAS, DART, Dublin Bus) covers the city well, and driving in central Dublin adds stress without much benefit.
However, if you're planning to explore beyond Dublin — the Wild Atlantic Way, Killarney, Galway, the Cliffs of Moher, the Ring of Kerry — a hire car is essential. Ireland's rural beauty is largely inaccessible by public transport.

The eFlow M50 Toll — Important for UK Drivers
The M50 motorway around Dublin uses a barrier-free electronic toll system called eFlow. There are no booths — cameras read your number plate and charge your registered account.
Your rental car will have a toll tag set up — charges are typically added to your credit card by the rental company, often with an admin fee of €2–€5 per transaction. This is normal and expected. Check your rental agreement for the exact fee structure.
