First of all, we should understand and master the meaning of various traffic lights: when the green light is on, traffic is allowed, but turning vehicles are not allowed to hinder the passage of straight vehicles and pedestrians; When the yellow light is on, no traffic is allowed, but vehicles and pedestrians who have entered the crosswalk can continue to pass after passing the stop line; When the red light is on, you are not allowed to pass. When the yellow light flashes, it must pass under the principle of ensuring safety.

The meaning of crosswalk signal: when the green light is on, traffic is allowed; When the green light flashes, pedestrians are not allowed to enter the crosswalk, and those who have entered the crosswalk can continue to pass; When the red light is on, no vehicles are allowed to pass.

When crossing the road, you should get into the good habit of watching traffic signals. At the same time, pay attention to traffic, and don't chase, rush, cross diagonally or suddenly change the direction of the road. Don't lean on the guardrail and isolation pier, and don't cross or drill through the guardrail and isolation pier to cross the road. Instead, take the overpass and underpass. In the distance where there is no crosswalk, you must go straight through, take the initiative to avoid passing vehicles, and don't rush when the vehicles are approaching.

On urban roads, white or yellow lines are generally used to divide the road into the slow lanes of motor vehicles, bicycles, human tricycles and other slow vehicles and the sidewalks of pedestrians. On the sidewalk, few people should not walk side by side. Try to pull over when there is no sidewalk. Junior students should be led by their parents when they go out. When walking, if someone crosses the road to say hello, don't cross the road suddenly to prevent accidents.

Pay attention when walking. Don't look around, read books and newspapers or forget to observe the road conditions because of thinking and chatting. That is likely to be accompanied by stones and wooden sticks on the road, hurting or knocking down trees and telephone poles, and even having a car accident. When there is a car parked on the roadside, you should pay attention to avoid it, so as to avoid being injured when the car suddenly starts or opens the door. You can't play football, roller-skate, jump rubber bands, play games or chase fights on the road, let alone stop a car, chase a car, stand in the middle of the road and forcibly stop a car or throw a parabolic object. Be careful when walking in foggy and rainy days. You'd better wear brightly colored clothes (preferably yellow), raincoats and bright umbrellas. When you go to the street at night, you should choose a lot with street lights, and pay special attention to traffic and road conditions to prevent accidents or accidentally falling into pits dug by the road and various uncovered wells.

When crossing the expressway, you should obey the instructions of the traffic police and obey the traffic rules, so as to achieve "stop at the red light, go at the green light" and "slow down, look at it, and pass through it three times"
