Traffic Safety Tips

If you are among those who think that traffic safety tips are something that need to be given to children and not adults, you are so very young. Being an adult, it is our responsibility to set a good example for others. Remember when you are driving a car with your teenaged son or daughter sitting next to you, he or she is watching you and observing how you drive. So make sure that you follow all the necessary traffic rules to set a good example. Some of the effective traffic safety tips are mentioned below.

Put Your Seat Belt On

The first thing that you are supposed to do, and make sure that others in the car also do, is to put your seat belt on. In case there is a child in the car between the age of 4 and 8, a booster seat(儿童座椅)should be used as safety belts are not meant for small children and cannot protect them in case of accidents. Kids under the age of 12 should never sit on the front seat.

1.________________

Do you drive, listen to music, eat your sandwich and speak on the phone all at the same time? If you do this, you are not displaying your super powers but allowing multiple things to distract you. Once you are driving, be it alone or with your friends and family, you are responsible for everyone

present in the car. So stop doing other things and focus on driving safe.

2._________________

Teenagers and young adults especially, don’t realize the risks they are putting themselves into. Alcohol influences your mood and mind and may not give you the judgment and control that you need to have when driving safe. Even smoking should be avoided and drugs should not be consumed if you are planning to drive.

3._________________

Driving under pressure with your mind occupied with issues at work or at home would easily allow you to distract your mind off the road leading to an accident. So make sure that you don’t let the things outside your car affect you when you are in the car. Sleep properly and stay relaxed before hitting the road.

4._________________

Your emotions or impatience may make you break the signal at times. Or break the speed limit because you are getting late. Don’t do that! The consequences for that may actually be enough to separate you from your driver’s license on a permanent basis. Make sure you obey the traffic rules and guidelines and do all to be a responsible citizen.

5. _________________

Last but not the least, keep your car in good condition. Make sure you are giving your car for servicing and maintenance on time. Make sure you always check your vehicle tires before hitting the road and don’t run out of gas!

So these were some of the main traffic safety tips that should be followed by one and all in order to stay safe and be an example for others. Remember, rules and regulations are made for your own benefit and safety. So make sure that you obey them. Take care and have a safe ride.
