In the Republic and Northern Ireland the maximum speed limit, which is shown in miles, are more or less the same as those in Britain.

• 30mph (50km/h) in built up areas
• 60mph (95km/h) outside built up areas
• 70mph (110km/h) on motorways

On certain roads, which are clearly marked the speed limits are either 40mph (65km/h) or 50mph (80km/h). Where there is no indication the speed limit is 60mph (95km/h). In the Republic, vehicles towing caravans must not exceed 55mph (90km/h) on any road. Speed limits are more strictly enforced in the North than in the Republic.
