Moving out or turning right
Extend your right arm out of the window and rotate it forward in a slow, deliberate circular motion. This signals your intention to move out from the kerb, change lane to the right, or turn right at a junction.

Hand signals.
Hand signals are used when indicators are not working, cannot be seen clearly, or when extra clarity is needed — for example, waving a following vehicle past when it is safe to overtake. They are required knowledge for the Irish driving test.
Book a lessonThe four hand signals
Official signals used in Ireland
All signals are given with the right arm out of the driver's window. Make the signal clearly and hold it long enough for other road users to see and react.
Slowing down or stopping
Extend your right arm horizontally out of the window with your palm facing downward. Move your arm slowly up and down. Use this when your brake lights cannot be seen clearly or when stopping at a pedestrian crossing.
Letting a vehicle overtake
Extend your right arm and make a slow, forward sweeping motion with your hand. This invites the driver behind to overtake when you have checked it is safe and clear ahead. Only give this signal when you are certain it is safe.
Turning left
Extend your right arm out of the window, bend your elbow upward at 90 degrees with your forearm pointing up, then rotate your forearm in an anticlockwise direction toward the left. Less common — use your left indicator wherever possible.
When to use hand signals
Signals support — they do not replace.
Hand signals should be used to supplement indicators, not instead of them where indicators are available and working. Common situations where hand signals add value:
- Indicator has failed or is not visible to a following driver
- Waving a driver behind you past when a long, safe gap exists
- Moving off from the kerb when traffic behind cannot see your indicator clearly
- Slowing at a pedestrian crossing to reassure a waiting pedestrian
- When directed by a Garda or traffic marshal and your signals are unclear
- On the driving test — the examiner may ask you to demonstrate a hand signal

Signals from others
Signals given to you by other road users
Not all hand signals come from drivers. You need to recognise signals from Gardaí and traffic marshals directing traffic.
Garda — stop (facing you)
A Garda facing you with their arm raised, palm toward you means stop. Come to a complete halt and do not proceed until directed.
Garda — proceed (side on)
A Garda standing side-on with arms extended straight out to their sides — traffic in line with their arm direction may proceed. Traffic facing the Garda must stop.
Garda — slow down
A Garda facing you with one arm raised and moving slowly up and down, palm facing downward, means slow down and proceed with caution.
