Why think of road safety？It is because of the accidents that occur every day on the road．These accidents means losing life or wealth and more than traffic jams．So if people aren't educated on the importance of road safety，the situation can't be avoided．
Accidents have many causes．The simplest is people slipping down on the road caused by a banana skin．Without meaning any harm，a person may throw away the banana skin on the road．When a person steps on，he or she will slip down ending in broken bones and sometimes even more dangerous．So people must take care and throw them in a bin．In some countries，the offenders are seriously punished．The second cause is careless crossing in busy road instead of crossing along zebra crossings．One should keep to the sidewalk of the road while walking and the vehicles must keep to their lanes in busy streets．
Also，there are many causes for the accidents about vehicles．One is trying to overtake．Another is not noticing the signals．"Stop，look and go"is the basic rule，it will save vehicles from accidents．Riding two or three side by side is always dangerous．Very often the cause of accidents is the failure of the brake system which means the owner of the vehicle does not keep the machine in good condition．
Road safety is a matter of education in which schools can share responsibility．Through class meetings，children can be taught the importance of observing the rules of the road．As soon as the bell goes，children rush out and accidents do happen．Therefore，teachers must feel it their duty to control the traffic near the school．The police can help schools at rush hours．
To make people aware of road safety，media can play a useful role．The newspaper，the wall poster and the cinema and now the TV can deliver information．There may be speeches over the radio by the police officials or advertisements about being careful on roads before films or TV programs．
