Veteran drivers talk about safe driving: How to drive on rainy, foggy, icy and snowy roads

1. Safe driving on rainy days

Side slipping and longer braking distances are the two major safety hazards of driving in rainy days. If it rains heavily, you must slow down and drive slowly. The tire treads of the guide wheel and the driving wheel are deep and consistent on the same axis. The brakes are not biased and the road is good anti-skid. You can drive at the specified speed. If one condition is missing, you need to slow down.

Generally speaking, the anti-skid performance of asphalt roads is better than that of cement roads. Of course, it cannot be generalized. Some asphalt roads are also very slippery, and some cement roads have deep grooves but are not slippery. You must observe carefully. , try to gently apply the brakes to find out. If a slight skid occurs when the brakes are applied, just release the brakes. If a side slip occurs if the brakes are not applied, an accident can be avoided unless the vehicle speed is very slow. Unqualified tunnel pavement has caused many side-slip accidents, tunnel leaks and water-spraying trucks.

Clean the workbench clean, use air conditioning to remove fog in summer, and use warm air in winter. You can use both hot and cold air in spring and autumn. Do not clean the glass while driving. There is water mist on the rearview mirror on the right door. When you turn right and cannot see clearly, you cannot drive blindly. You must confirm safety before driving.

When wading into deep water, seal the transaxle breathing hole to prevent gear oil from entering. There are fewer vehicle inspections and fewer pedestrians on rainy days. It is a profitable weather, but there are often losses, that is, the goods get wet. It is important to have a waterproof raincloth. You should bring a new plastic sheet to cover the car. Use it when you encounter goods that are particularly afraid of water. When driving on rainy days, you don’t have to worry about damage to your cargo. You feel at ease and can concentrate on driving, which is conducive to safety.

1. Safe driving in foggy days

Accidents occur frequently in foggy days, due to excessive speed and water droplets on the road. This is caused by two reasons. When the temperature is below zero, water droplets freeze. Not to mention rear-end collision, if you apply the brakes hard, you will slide sideways and hit the guardrail. Follow the car in the main lane slowly. If you feel that the car in front of you is too slow and there are brake lights, it is time to continue following.

Never follow an overtaking vehicle in the passing lane. It is better to overtake yourself and control your speed. If you feel that the car in front of you is going too fast, don't follow it, take the lead, accelerate out of the fog, and apply the brakes when you see the fog. In dense fog, you must not occupy the road to park. You can only run slowly. When you can only drive at 20 to 30 miles per hour, and you feel that there is still a long foggy road ahead, you can find a safe place to park. , or there is a traffic jam, indicating that you are out of the dangerous period.

2. Safe driving on icy and snowy roads

In hot weather, you need to reduce the speed to prevent punctures. You must also take care of the power and transmission parts and do not use excessive force because the lubricating oil will be high temperature and the lubrication performance will be reduced. , mechanical accidents often occurred because of this in the past, but things are much better now. In the cold winter, many problems are prone to occur. The gear oil thickens and can easily hurt the pig's mouth. After starting a cold car, you must drive slowly for more than ten kilometers. Only after the gear oil warms up can you drive at high speed. Do not drive at high speed when you just wake up. , after starting the cold car, I went to climb a long steep slope.

Check the performance of the dryer. There should be no water in the air storage tank. Otherwise, one or more of the control valves will freeze and cause many failures. The clutch master cylinder and slave cylinder are easily damaged, and the control valve is prone to leakage. Raise the cab for inspection and repair. If the cab cannot be lowered, the hydraulic oil is waxy and needs to be heated with a blowtorch.

After switching to -35 fuel tank, let the engine run for a while to prevent the diesel from waxing. When parking in extremely cold areas, start the engine every once in a while. Do not freeze the diesel. Even with a blowtorch and starting fluid, it will take a long time to start the engine.

If you ask a repairman for help, he will replace the diesel filter for you, which will cost a lot of money. The car is stuck in the sand. The more it moves, the harder it will be to pull it out, and the more money it will cost. The same is true when the diesel is frozen. You should save power and make sure the oil pipe is clear and there is no air before starting the engine.

Driving at night in winter is most afraid of dark ice. On cement roads, dark ice is black in color and easy to identify. You can brake in advance. You can also identify it on asphalt roads. When driving in snow, apply the brake lightly and determine the speed according to the road conditions. The fresh snow in northern Xinjiang is not too slippery. Use warm air to blow the glass, and keep stopping to clear the ice and snow on the rearview mirror and wiper blades, otherwise the wiper blades will break down quickly.

On icy and snowy roads in mountainous areas and plateaus, the front four and rear eight drive wheels are equipped with four anti-skid chains, which can pass through steep slopes and sharp bends. Four-wheel drive tractors are also equipped with four, and their passing ability is worse than the four in the front and the eight in the rear. The cargo can sink forward a little better. Most people only carry two anti-skid chains. If they break when idling when starting, they must use four anti-skid chains.

It is necessary to install anti-skid chains on the outer wheels of the front and rear driving wheels so that you can start on steep slopes and sharp bends. If you cannot start and need to back up the slope, you should sprinkle more on the road you want to pass. This move is very dangerous due to sandy soil, so be particularly careful. On sections with turns, the inter-wheel differential lock cannot be activated, only the inter-axle differential lock can be activated.

Although the passing performance of the inter-wheel differential lock is doubled, it cannot be used in sharp corners. Some Tibetan semi-trailers are very safe and are equipped with ten anti-skid chains in the snow. Some drivers say that the reason why they move the anti-skid chains to the trailer when going downhill is because the trailer brakes first and the tractor brakes later.

This method is not completely correct, and it is too troublesome. It is better to go down slowly, on steep slopes and sharp bends, with the gear in hand, and keep lightly applying the brakes. The speed of the car is about the same as walking. Even if the engine brake switch is accidentally touched, sideslip will not occur because there are anti-skid chains on the driving wheels. Engine braking and retarder braking should be used with caution on rainy days and must not be used on snowy or muddy roads.
