Keep safe (保持安全)
This is a street crossing. There are red and green lights at each corner(拐角). Drivers must watch the lights carefully.
When there is a green light, the cars may go on. 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. Sometimes 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 colour-blind(色盲的). They cannot see the differences between red and green. These people must not drive, or there will be accidents. We must keep our street safe.
