While the Irish car rental fleet transitions to electric vehicles, many are still fuelled by unleaded petrol or diesel. Be careful when refuelling as using the wrong fuel will damage the engine. The nozzles are usually colour-coded to indicate which type of fuel they dispense. A black handle in Ireland indicates that the fuel dispensed is diesel while a green nozzle indicates unleaded petrol. This is the opposite of the common colour-coding in the USA. If you realise you have put the wrong fuel in the car, do not start the car. Contact your car rental company immediately.
In the Republic of Ireland signposts and placenames are displayed in both Irish (Gaelic) and English, and distances on signposts are in kilometres. Speed limits are in kilometres per hour. In Northern Ireland signposts and speed limits are all in miles.
As in most countries if you park in restricted areas, you may be fined, and/or the vehicle towed away. A single yellow line parallel to the footpath indicates restricted parking and vehicles should never be parked were there are double yellow lines. In the main cities watch out for clearway signs. A vehicle must not be parked in clearways/bus lanes between designated times, or it will be towed away. Renters are fully responsible for payment of parking fines, clamping charges and all Road Traffic fines.
