     Young children don't have the skills or knowledge to stay safe in heavy traffic. The following tips (忠告)

will be helpful for you to keep your children safe in heavy traffic. Children learn about road safety by watching

others. Make sure that you always set good examples. Your children will follow you and think it's OK to do

like you. Teach your children to pay attention to traffic lights when you cross the road together with them.

This helps them understand when it's safe to cross. Make sure that you walk between your children and

traffic, and hold their hands all the time.

     When your children are a little older, you can start to tell them the importance of traffic knowledge. Let

them start to understand the reasons why they need to be so careful. Talk with them about road signs and

traffic rules.

     Ask your children to play in a safe place. Never let them ride bikes on the road without an adult present

at rush hour.

     The most important thing you can do to keep your children from getting hurt is to encourage them to

follow traffic rules. After knowing about traffic rules, they'll volunteer to obey them. In this way, they'll be

careful enough to keep themselves away from danger.
