Wow it's just a part of our traffic laws that you indicate which way you want to go here. You can get a misdemeanor and a fine for not using your turn signal.They wouldn't be so bad if people used their indicators to let other drivers which exit they're taking. It amazes me how many drivers don't indicate at junctions. I think it's illegal in Australia and I think it would be much safer if it was here too. It's second nature to me but younger drivers can't be bothered. Some don't even indicate when changing lanes on motorways etc which often causes accidents.
