Precautions for long-distance driving:

First, check before travel.

Be sure to check all parts, tires, lights, oil, wipers, etc. Especially for long-distance and high-speed driving, especially tires, repair them in time when problems are found. After all, it is very dangerous to have a flat tire in expressway.

After driving on expressway for more than 2 hours, you need to rest and adjust your state. The car also needs to rest and adjust its state, so as to ensure your driving safety in the next trip.

Second, control the speed

Slow down, look at it, pass it. Slow down, look, it sounds nagging, but it is a real life-saving strategy. "Nine times out of ten accidents are fast" is not an empty talk. Slow speed is a necessary condition to reduce the accident rate and improve the survival probability. But you can't drive too slowly. You should drive at the prescribed speed. Especially when entering the ramp at a low speed, you must have a sense of deceleration, and many people will overspeed on the ramp.

Third, don't change lanes frequently.

Generally speaking, there are three lanes in expressway. According to common sense, expressway will not occupy overtaking lanes or slow lanes for a long time. Try to take the middle lane, because both sides of the road are wider. If there is a vehicle accident on the side or before and after, the driver walking in the middle lane can take timely action to avoid a collision accident.

Don't change lanes frequently unless there are special circumstances. Many traffic accidents are caused by changing lanes. If you must overtake or change lanes, be sure to turn on the turn signal for three seconds before operating.

Fourth, stay away from the cart.

Stay away from the cart, stay away from the cart, stay away from the cart. The important thing is to say it three times, because the big truck is limited by the blind area and its own weight, not only the braking distance is long, but also because it is difficult to see the car in the blind area, it is easy to have an accident. At the same time, in the event of an accident, the probability of damage to private cars is much higher than that of large trucks.

So don't get too close to the big truck, especially don't drive parallel to the big truck. When you meet a big truck, you can decisively overtake.
