Signal
well before the action.
Indicators warn of your intention to turn or diverge or stop, not
that you are already doing it.
Example: When
parking the car at the kerb - indicate before reducing speed. Traffic
behind will expect you to stop, and move around you! Slowing down,
looking for a space without indication, confuses traffic behind. You risk a
rear-end collision.
If your
indicator warning fails (listen for sound and warning light), have it repaired
immediately. Crashes caused by faulty indicators are common.
Do not act
on another vehicle's indicators, until you are sure the action indicated
by the other motorist is what he or she will do.
