Turning: When to signal

When driving in residential areas you should signal around 30 meters (100 feet) in advance of making a right or left turn. This assumes there are no other turns on the same side of the road before the turn you intend to take, otherwise you’ll need to signal after that turn to avoid confusing other road users. For faster roads, this distance increases. On a dual carriageway at 70 mph, for example, signalling should start from around 275 meters (900 feet) from your exit.
