用装载能力为10吨的汽车来运送救灾物质43吨，那么至少需要这样的汽车______辆．

Wearing seat belt is，of course，the first step to safe driving．These additional measures might also save your life.

Count to three．Keeping up enough space between your car and others is extreme1y necessary．Jim Clark，a California driving instructor，suggests a least amount of three seconds’following distance．To figure this，pick an object on the roadside ahead．When the car in front of you passes it，start counting one-thousand-one,one-thousand-two，one-thousand-three．If you get to that object before you reach one-thousand-three，you don’t have three seconds of following time --- time needed to keep away from accidents．

Let followers pass．“If someone’s driving after you，get out of his way，”Clark advises．“You’re better of being safe than right．”

Expect the worst．In a study，the Federal Highway Administration(联邦公路局)found that 68 percent of drivers do not come to a complete stop at stop signs．When you’re driving and see someone come near to a stop sing，assume the person’s not going to stop．

And when you stop at a crossing and another car comes near with its turn signal on，don’t take it true that the driver will turn．Instead，wait until he turns．He may have had the signal on for miles．

Stay outside．In crowd，multilane(多车道) traffic，drive in either the outside--left or outside--right lane．“That allows you somewhere to go if a problem develops,”traffic expert Francis Kenel says．“If you’re in the middle，all you can do is to pause from time to time．”
