i dont know if they are the same where you are but the bike signals that you use when biking with your hands. i have been taught them but ive forogtten them a bit. No one retains them very much anymore and when i look at the ones you are supposed to do when you are turning right you put up youre left hand??
you also gotta know that alot of divers dont know or remember the bike signals nor can they figure them out when you drive...maybe they should change them to allow both bike and car dirver to understand which way they are going..
sorry for not posting lately
