Road sign questions are a guaranteed feature of every theory test. Ireland has over 150 different road signs, and you need to know what each one means.
The Three Types of Road Signs
1. Regulatory Signs (Circular)
These tell you what you must or must not do. They’re circular with red borders (prohibitions) or blue backgrounds (obligations).
- Red circle with white background = prohibition (e.g., no entry, speed limit)
- Blue circle = mandatory instruction (e.g., turn left, minimum speed)
2. Warning Signs (Diamond-shaped)
These warn you of hazards ahead. They’re diamond-shaped with a yellow background and black symbol.
- Sharp bend ahead
- Crossroads
- Pedestrian crossing
- Road works
3. Information Signs (Rectangular)
These give you information about directions, distances, and facilities. Colours vary:
- Green = motorway information
- Blue = national road information
- White = local road information
- Brown = tourist information
