Precautions:

Don't overload, don't let five people take six people, and don't jam the car into canned fish, which will increase the chance of accidents.

Don't overspeed, don't encounter emergencies and bad weather, and don't be too slow. Different highways have different speed limits, and different lanes have different speed limits. Please follow the road signs strictly. Some expressways have separate lanes for passengers and goods, so we must pay attention to them.

Maximum speed limit of domestic high speed 120mph. No matter which expressway you take, you must not exceed 120mph. If the vehicle speed is too fast, the braking distance will be longer, which is prone to danger at high speed. In addition, the faster the speed, the more unstable the car is, the greater the influence of the fast wind on the side, and the higher the probability of out-of-control rollover.
