This is a street
crossing. There are red and green lights at each corner. Drivers must watch the
lights carefully.
When there is a green
light, the cars may go. When there is a red light, the cars must stop. They
must wait until the red light changes to green. Then they can go on. Sometimes
the cars want to make a right turn or a left turn. They can make a right turn
when the light is green or red. But they must wait until the green light is
shining if they want to turn left.
Some people are
color-blind(色盲). They can not tell the difference between the red and green
lights. These people must not drive, or there will be accidents. We must keep
our streets safe.
