     Many Chinese have been greatly shocked by the traffic accident caused by the drunk driver Sun

Weiming,  who has killed five and injured some others in Chengdu, Sichuan. However, such a case is

not rare.

     Today, traffic accidents may have been regarded as a social problem. The car has killed and

disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood

on the street flows actually from rude behavior of drivers who refuse to respect the legal and moral

rights of others. In fact, the enemies of society on wheels are rather harmless but just ordinary people

acting carelessly, you might say. But it is a principle both of law and common morality that carelessness

is no excuse when one's actions could bring death or damage to others. A minority of the killers go

even far beyond carelessness that can be imagined.

    Researchers have estimated that as many as 80 percent of all automobile accidents can be attributed

to the psychological condition of the driver. Emotional upsets can change drivers' reactions, slow their

judgment, and make them blind to the dangers that might otherwise be evident. The experts warn that

it is vital for every driver to make a conscious effort to keep his/her emotions under control.

     Yet the irresponsibility that accounts for much of the problem isn't only put upon drivers. Street

walkers regularly ignore or break traffic regulations. They are blamed in most vehiclewalker accidents,

and many cyclists even believe that they are not subject to the basic rules of the road.

     Significant legal advances have been made towards safer driving in the past few years. Safety

standards for vehicles have been raised both at the point of manufacture and through regular road

inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate

has decreased. But the accident experts still worry because there has been little or no improvement

in the way drivers behave. The only real and lasting solution, say the experts, is to make people believe

that driving is a skilled task requiring constant care and concentration. Those who fail to do all these

things present a threat to those with whom they share the road.
