Some drivers fail to yield properly. Be prepared to brake if a vehicle emerges without yielding. Check your left mirror before passing the junction in case vehicles are accelerating from the side road. If you are turning left into the side road, signal early (at least 5 seconds before), check mirrors, reduce speed to 20-30 km/h, and observe for pedestrians crossing the side road entrance.
