What must a motorcycle rider do before making a U-turn on a NSW road?

1. Signal left, then make the U-turn as quickly as possible
2. Check that no 'No U-Turn' sign is displayed, that the turn can be made safely without impeding traffic, and signal right before turning
3. Only check for traffic from the right — oncoming traffic has right of way
4. U-turns are always prohibited; a rider must make two right turns instead
