12 122 is not only an expressway traffic inquiry telephone, but also an emergency alarm and rescue application telephone. At present, expressways in all provinces of China have been connected to this telephone network. If you encounter an emergency on the expressway, you can call the hotline 12 122.
Matters needing attention when driving on the expressway:
1. Make clear the lanes, overtaking lanes and road signs: the overtaking lanes are near the median of the expressway. Don't stay in the overtaking lane for a long time if you don't overtake. The general emergency lane is on the far right. Don't overtake in the emergency lane, it's dangerous. Generally drive in the driveway, but pay attention to keep a distance from the car in front.
2. Driving speed: The slower the speed, the safer it is. It is safer to drive at a speed of 80 to 100 km (there will be speed limit tips on individual sections, such as downhill or curve). If it is too slow, the car behind it sometimes can't hide, and it is easy to rear-end.
3. Be sure to turn on the high beam when driving at night: this is far and safe. When overtaking, you must turn the left turn signal and tell the car behind you to change lanes to overtake. After overtaking, you must turn on the right turn signal and return to the lane quickly. The distance between overtaking and rushing to answer is at least about 100 meters according to the speed.
4. Get off the freeway: When getting off the freeway, be sure to look at the next stop. Once you miss the next stop, keep going and get off at the next exit. Remember not to reverse or turn around. Many cars reversed just after the next stop, which caused tragedy, because the cars behind them could not see the reversing at all. So it is dangerous.
5, long-distance high-speed driving: the most dangerous thing about long-distance high-speed is fatigue, it is best to have a substitute driver, fatigue driving is too dangerous. Also, run for a period of time, pay attention to the brakes and check whether the brake system is normal.
