阅读下面短文，从各题所给的四个选项(A、B、C和D)中，选出最佳选项。

If you are cycling in foreign countries, you will need to know what these traffic signs and signals mean.

1.	A sign like this one means that there is a bike lane (车道). If there is such a sign, you are required to use the bike lane. If there is not such a sign, you should ride with traffic as far to the right side of the road as possible.
2.	This signal means you can cross the street along with pedestrians (行人). It has a green picture of a person walking instead of using the word "walk".
3.	This signal is the "don't walk" sign. It is a picture of a red hand, meaning you should stop. You should wait to cross the street until the green picture of the person walking is showing.
4.	Car drivers and bikers must come to a complete stop at "STOP" signs.
5.	A "YIELD" sign means to slow down and be ready to stop. If there are pedestrians or vehicles in or near the crossroad, you must stop. If there is no traffic in or near the crossroad and it is safe, you may go through.
6.	This signal means you are coming to a zebra crossing. Car drivers and bikers must stop to allow people in the zebra crossing to cross the street.
7.	When people are working on the roads, parts of the road are often dug up or rough (不平整的). Be careful when you are cycling. Rough roads could make you fall off your bike. If you must move into the road to go around a work area, you should stop and look carefully to be sure there is no traffic coming.
8.	A detour is a way of getting around a roadway that is closed. Roads are usually closed because of road work or dangerous conditions. If you must take a detour, be careful about the roads you aren't used to.
