If you will be cycling, you will need to know what these traffic signs and signals mean.
A sign like this one means that there is a bike lane. If there is a bike lane, you are required to use it. If there is not a bike lane, you should ride with traffic as far to the right side of the road as possible.
When the signal light turns green, cars go. When you cross the street at a signal light, you should wait for the walk signal. Be sure to look carefully to the left, right and left again, before crossing the street.
When the signal light turns yellow, car drivers should slow down and prepare to stop. You should not cross if the light is yellow. The light is about to turn red, and cars will enter the intersection.
This signal is the WALK sign. It has a picture of a person walking instead of using the word WALK.
This signal is the DON'T WALK sign. It is part of the signal with the picture of a person walking.This 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.
Car drivers and bikers must come to a complete stop at STOP signs.
A yield sign means to slow down and be ready to stop.
If there are pedestrians(行人)or vehicles in or nearing the intersection，you must stop.
If there is no traffic in or nearing the intersection and it is safe，you may go through.
This sign means you are coming to a crosswalk. Car drivers, antibikers must stop to allow people in the crosswalk to cross the street.
When people are working on the roads, parts of the road are often dug up or rough. Be careful when 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 before going into the road.
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 of roads you aren't used to.
