Because there are so many bikes, cars and buses on the roads all the time, it is very important for riders(骑车人) to remember the traffic rules. Young children may not ride bikes in the streets, because there are so many cars and buses that it is dangerous. A rider should keep one hand on the handlebars(把手) at all times. You should ride on the right of the road. Like a driver of a car or a bus, you must follow all traffic signs. Everybody knows that you must not turn left or go across at a red traffic light. Usually you can turn right, but you shouldn't ride too fast. If you want to turn or stop, you must give a sign to other riders.
