on the car What needs to be tested before the highway

Generally, tires, oil, antifreeze, lights, brakes and battery lights should be checked. Check the following items before getting on the highway: First of all, tires. Carefully observe whether there are scratches on the appearance of each tire. If it's just a rubber scratch, it doesn't affect the use, but if the inner tire line is damaged, a new tire must be replaced.

The vehicle before entering the highway needs to be checked as follows: check the condition of the vehicle: such as fuel gauge, tire pressure, lighting, braking, etc., and also check the spare parts, such as fault triangle, jack, spare tire.Check the amount of fuel: When the car is driving at high speed, the fuel consumption is much more than expected.

Light. Including running lights, reversing lights, brake lights, turn signals, in-car lights, fog lights, etc., especially fog lights, if there is a problem, they need to be replaced immediately. Brake. Look at the thickness of the brake pad. If it feels too thin (less than 2mm), it needs to be replaced. Drive at normal speed, step on the brake to see if there is any abnormality.

Is it better to use the highway or the railway

Railway consignment: Advantages: affordable, especially for car owners who need to transport cars for long distances, railway consignment can provide better economy. In addition, railway consignment can also provide safe and stable transportation. Disadvantages: Lack of flexibility, can only be checked in at a specific time and place, and the car owner needs to plan and arrange the time in advance.

It is suitable for road transportation within kilometers, which is relatively safe and fast. And more than 1,000 kilometers, especially in the southwest, Xinjiang and Tibet, are suitable for railway transportation, which is safer. Fragible goods that are not easy to load and unload are suitable for highways. One-point loading, one-point unloading, and not easy to damage. Railways are very likely to be damaged, and brutal loading and unloading is very common.

Railway transportation Railway transportation has strong transportation capacity, which can transport a large number of vehicles at one time, and the transportation is safe and stable, and will not be affected by weather, traffic and other external factors. In addition, railway transportation is cost-effective, the consignment price is lower than that of road transportation, and railway shipping is less affected by policies, and the price is stable. It is generally suitable for long-distance transportation.

Advantages of road transportation: convenient and wide coverage. It is mainly applicable to the transportation business of daily private cars, commercial vehicles and second-hand cars.Followed by railway transportation. The means of transportation is: train. The load capacity of the train is higher than that of the board car. Advantages: high loading capacity and safety.

High flexibility, most cities across the country can be reached, and the timeliness is good. In today's society, China's road transportation can be said to be well-reached. For the vehicles used for consignment, it can meet the needs to the greatest extent. If the distance is close, it will be more convenient to choose highway consignment.

What are the requirements for highways when cars are driving?

Modern highway transportation not only requires sufficient strength and stability of the road mask, but also meets the requirements of flatness, anti-slip, etc., while reducing environmental pollution. When a vehicle with sufficient strength drives, it not only produces vertical pressure on the road, but also makes the road surface bear a longitudinal horizontal force.

First, the design requirements of the longitudinal slope. If the longitudinal slope is too large, it will lead to longitudinal overturning and longitudinal slip when the car is driving uphill. Second, when designing flat curves, horizontal ultra-high should be set to reduce the impact of centrifugal force.

What are the requirements according to the Traffic Safety Law for planting trees or other plants on both sides of the road and isolation belt, setting up billboards, pipelines, etc.? The necessary distance should be maintained from the traffic facilities, and the street lights, traffic signals and traffic signs shall not be blocked, the safety visual distance shall not be obstructed, and the traffic shall not be affected.

Road design and maintenance requirements Road design requirements Roads refer to highways, urban roads and places where social motor vehicles are allowed to pass within the jurisdiction of the unit, including squares, public parking lots and other places for public traffic.

Highway grades are divided into several levels

1. Function and flow are divided. Mainland China divides highways into highways. , first-class highway, second-class highway, third-class highway, fourth-class highway, a total of five levels (digital classification is the traditional classification system, and highways are new).

2. China's highways are divided into four levels, and the first-class highway is the national highway;The second-level highway is the provincial highway; the third-level highway is the county highway; the fourth-level highway is the township highway.

3. Highways are divided into five levels: expressways, first-class highways, second-class highways, third-class highways and fourth-class highways. Expressway. Expressway refers to a multi-lane highway that is dedicated to driving in different lanes for cars and should be fully controlled. Expressways have different regulations in different countries and regions, different eras and different scientific research and academic fields.
