Analysis of safety precautions for driving in hot weather

Since July, the temperature has continued to rise in most areas, and the hot weather has also brought stress to driving. So what should you pay attention to when driving on a hot day?

1. Stop cooling when the water temperature is high

High water temperature is a common phenomenon for vehicles in hot weather. Turn off the air conditioning system before turning off the engine. When driving, if you find that the pointer of the thermometer is close to the red line, you should slow down as soon as possible and stop the car in a cool place.

To avoid damaging the engine, do not turn off the engine immediately after parking, but let the engine idle for a period of time. If the water temperature still does not drop, stop the vehicle and check the engine coolant. But be careful not to open the water tank cover immediately, otherwise you may be burned by steam.

2. Pay attention to whether there are any signs of spontaneous combustion such as odor or noise.

Old vehicles that are more than four or five years old may be at risk of spontaneous combustion. Car owners should pay attention to regular inspections to see if there are aging oil pipes, wires, etc. , and whether there are exposed wires or oil leaks.

While driving, car owners should pay attention to signs of spontaneous vehicle combustion, such as odor, abnormal noise, or vehicle electrical failure. When a vehicle spontaneously ignites, park the vehicle in a place with few people, turn off the fire immediately, take out the fire extinguisher, find the ignition point, cool the fuel tank and burning parts to extinguish the fire to avoid explosion.

3. Brake slowly after puncture.

In hot weather, pay special attention not to let the tires collide with obstacles such as road teeth, because this can easily damage the sidewalls of the tires and cause hidden dangers. If a tire blowout occurs while driving, the driver should control the steering wheel tightly with his hands and slowly apply the brakes to slow down the vehicle and stop it smoothly. Never brake suddenly, as this can easily cause the car to spin or even roll over.

4. Prevent emotional agitation

High temperatures can easily make people feel irritable, and drivers are no exception. Once encountering external stimuli (such as other vehicles squeezing into the road, high beam lights not turning off at night, etc.). ), it is easy to arouse emotions and lead to extreme behaviors, such as stopping the car, overtaking and turning sharply, and being brighter than the lights at night. , which can easily lead to accidents. When driving, you can play some light music to relax and keep your mind calm and normal.

5. Prevent fatigue driving

High temperature can easily make people tired, affect the driver's attention and judgment, cause slow action, premature work, stop work or improper correction time, etc. Unsafe factors can easily lead to road traffic accidents. Therefore, as a driver, you must pay attention to the balance between work and rest, especially during the London Olympics. Remember that watching TV will not affect your rest, so you must have enough sleep and rest time.

6. Prevent battery water loss

When the temperature is high in summer, the water in the battery electrolyte evaporates quickly, the liquid level drops quickly, and the plates are even exposed to the liquid surface, causing the battery to Early damage due to "lack of water". Therefore, the liquid level in the battery should be checked frequently in summer and distilled water should be added in time.

7. Prevent brake failure

Brake fluid is easy to evaporate in high temperature environments, forming an air lock in the brake pipeline, and the brake shoes are easily ablated, resulting in brake failure. . Therefore, the brake system should be checked and adjusted in time in summer, brake fluid should be added or replaced in time, the air in the hydraulic brake system should be completely drained, and the brake cup, brake hose and brake shoe should be ensured to be in good condition.

8. Prevent poor lubrication

When the temperature is high, the viscosity of the engine oil decreases and the oxidation resistance becomes worse, resulting in poor lubrication. Therefore, high-grade engine oil (such as E-CA40) should be replaced in time in summer, the oil quantity and quality should be checked frequently, and added or replaced in time.

9. Prevent vehicle spontaneous combustion

In hot weather, vehicles should not be filled with fuel. Car fuel tank caps are equipped with ventilation holes. If the gasoline is filled up, the bumps in the road will cause the gasoline to spill out, and static electricity can cause a fire. At the same time, it is necessary to strengthen the inspection of electrical circuits to prevent aging and fire.

Smoking drivers should also remember not to place lighters and other flammable and explosive items in the car to prevent the lighter from exploding or spontaneously igniting and causing a fire after the vehicle is exposed to strong sunlight.

10. Prevent tire bursts

In midsummer, accidents caused by punctures occur from time to time. Under high temperatures, the road surface temperature will probably reach 60℃-70℃. If the tire pressure is too high, once a foreign object slightly touches the weak part of the tire, it can easily cause a puncture. Therefore, be sure to check your tire pressure in the summer, especially before driving on the highway.

11. Anti-gas lock

The higher the temperature, the faster the fuel (especially gasoline) evaporates, and the easier it is to form an air lock in the oil circuit. Therefore, the fuel filter should be cleaned in time in summer to ensure that the oil circuit is smooth. When driving, a wet cloth should be covered on the fuel pump and water should be sprayed regularly to keep it moist and reduce the occurrence of air lock. Once an air lock occurs in the fuel system, the vehicle should be stopped immediately for cooling, and the manual pump should be turned on to add fuel to the oil line.

12. Prevent distress on the way

The weather is hot, the road surface is dusty, the adhesion coefficient decreases, and the asphalt road surface softens in the sun. When braking, the asphalt on the surface sticks to the wheels and is exposed, reducing braking performance. Drivers should drive with caution. At night, you should also pay attention to people sleeping on the roadside and in the shade of bridges to prevent collisions.

When passing a road paved with crops, you should drive slowly, do not use the brakes easily to prevent sideslip, and do not touch stacked crops and electrical appliances.

Watch out for people taking a break during this time, and be careful to prevent people from suddenly crossing the road from piled crops. After passing, you should also stop and check whether there are crops on the car's engine oil and exhaust pipe.
