Turn signalsIreland
137. Turn signals
Turn signals, also called direction indicators, are flashing lights used to communicate a driver's intention to turn or move laterally, such as when changing lanes. They normally flash on the side towards which the vehicle intends to move.
Turn signals should be activated early enough to give other road users useful warning and should be cancelled once the intended movement has been completed. Signalling does not itself give the driver priority or make an unsafe manoeuvre permissible.
