The Speed Limit Sign– 100km/h – RUS 040 | Permanent Ireland Traffic Sign is a mandatory regulatory sign that clearly indicates the maximum legal speed limit of 100 kilometres per hour. Featuring bold black numerals and “km/h” within a red circular border, this sign is used to enforce speed regulations on Ireland’s national secondary roads and selected rural routes.

As outlined in Chapter 5 of the Traffic Signs Manual (TSM), the RUS 040 sign ensures that all drivers—private, commercial, and public transport—adhere to road-specific speed rules, enhancing safety, reducing accident risk, and supporting enforcement. It is a legal requirement under the Road Traffic (Traffic and Parking) Regulations and must be clearly displayed at transition points and road boundaries where the 100 km/h limit begins.
