Road and traffic signs in Ireland, and what they mean
All 215 signs in the RSA's Rules of the Road, with the official name of each. Learn them by group: the shape and colour tell you what kind of sign it is before you read the symbol.
“Regulatory signs show the course a driver must follow and an action they are required to take or forbidden to take. They are usually circular and have a red border and black symbols or letters on a white background.”
Warning signs warn of a hazard ahead.
“They are diamond or rectangular in shape and have a black border and black symbols or letters on a yellow background.”
Signs for roadworks:
“Like other warning signs, these are diamond or rectangular in shape and have a black border and black symbols or text. However, they are orange in colour instead of yellow.”
