Road safety
Road safety is very important for everyone. We must look at the traffic lights carefully when we cross the road. We should cross the road at zebra crossings. We mustn't run or play ball games on the road because it's dangerous. We have to wait for the green light before we walk across the road. We should also look out for cars and bikes. If we follow these rules, we can stay safe on the road.
