How to drive safely in summer?

Summer is still unbearably hot. Driving under the scorching sun in summer, the driver is not only uncomfortable, but also upset; The racing car was also affected by the high temperature. How to drive safely in hot summer?

Introduction to safe driving in summer

Steps/methods

1, common sense of safe driving

In summer, we should always check the technical condition of vehicles, focusing on the safety components of vehicles. It is forbidden to drive cars with illness on the road. Before driving in summer, drivers must ensure adequate rest and sleep, maintain abundant energy, and it is strictly forbidden to drive vehicles with fatigue. Driving in hot weather should be controlled to avoid driving at high speed for too long, so as not to cause the engine or tire temperature to be too high. Pay close attention to the dynamics of non-motor vehicles and pedestrians when driving, and beware of non-motor vehicles and pedestrians suddenly crossing the road to avoid the cold and heading for the shady side of the road.

2. Avoid excessive engine temperature.

When driving a vehicle in hot weather in summer, always pay attention to the change of the water thermometer, generally not exceeding 95℃, especially when the vehicle is fully loaded or driving on a mountain road, and pay more attention to prevent the engine from overheating. If the temperature is too high, stop in the shade to cool down in time, and lift the hood for ventilation and heat dissipation; After the temperature drops, check whether the engine cooling system is short of water and the reason for the high temperature.

Do not turn off the engine immediately when the coolant boils due to overheating or lack of water. Stop the engine and run at idle speed. When the temperature drops, turn off the engine, and then open the radiator cover with cotton yarn or gloves to prevent the driver's hands and face from being burned by boiling cooling water.

3. Observe the tire temperature.

It is not advisable to drive for a long time in summer. After driving for a certain distance or every 2 hours, check the tire temperature when stopping properly. When it is found that the tire pressure rises due to overheating, you should try to park your car in the shade or under the shade to let the tire naturally cool down and depressurize. It is not allowed to deflate or pour cold water to reduce tire pressure and temperature. In addition, emergency braking should be avoided when driving in summer, and it is strictly forbidden to overload and overrun vehicles.

Step 4 avoid fatigue driving

Driving a vehicle in hot summer weather or overheated cab has high temperature and poor air circulation, which makes the driver easily tired; I often feel mentally exhausted, my vision is gradually blurred, and my thinking becomes dull. Especially when driving in the afternoon or midnight, I will feel very sleepy, and even the driver will lose his memory instantly. Driving reluctantly will lead to traffic accidents. When driving in hot weather in summer, try to keep the air in the cab unobstructed and the temperature and humidity appropriate. When you are tired, you should stop and rest in time, and you should not drive the vehicle reluctantly.

Drinking and driving in summer is more harmful.

The weather is hot in summer, and the human body temperature is relatively high. After drinking, the alcohol absorbed into the blood reaches all parts of the body faster, and the brain is most affected. Because alcohol has a paralyzing effect on people's brains, it affects the functions of all systems in the whole body, which leads to drivers' inattention after drinking, reduced ability of perception, judgment and comprehensive analysis of external accidents, narrowed vision of eyes, slow response, clumsy movements and poor accuracy of maneuvering actions, so braking and maneuvering avoidance actions are inaccurate in an emergency. In severe cases, people will be highly excited and lose control of their emotions. During driving, there will be illegal acts such as speeding, overtaking, grabbing signals and running red lights. It is easy to cause traffic accidents and even hit and run.

Refuse to drive too fast

When driving in hot weather in summer, the road surface temperature is high, and the residual oil road surface will be submerged and melted, which will increase the driving resistance of vehicles. When the vehicle is speeding after heavy load, the intense friction between the tire and the road surface will lead to the continuous increase of tire temperature, which will lead to a tire puncture accident and easy to slip after rain. In addition, speeding will increase the driver's psychological pressure. The higher the speed, the heavier the psychological burden, and the more prone to impatience, even sweating and operational errors, leading to traffic accidents.

Driving at night needs to be more careful.

Before driving at night in summer, all lights and mirrors should be checked to ensure that the lights are normal and the mirrors are neat; Driving at night, using high beam when the speed exceeds 30km/h; When the vehicle speed is within 30km/h, the low beam lamp can be used. When passing at night, you should cooperate with the other vehicle to change the far and near lights at a long distance and observe the situation ahead; When it is away from the opposite direction150m, switch to the low beam in time; Don't look directly at the bright light from the oncoming car. When passing through urban areas, villages and towns or bridges, slow down, pay attention to people walking on both sides of roads or bridges to enjoy the cool, and make emergency preparations at any time.

Emergency treatment of puncture

When driving, sudden puncture is a hidden danger of safe driving in summer. In case of sudden puncture, the driver should hold the steering wheel tightly with both hands, release the accelerator pedal and try his best to control the vehicle to drive straight. If there is a turn, don't overcorrect it. In the case of controlling the direction, lightly step on the brake pedal (no emergency braking) to slow down the vehicle slowly. When the speed drops to an appropriate level, stop the vehicle smoothly and try to park the vehicle on the side of the road gradually.

Never slam the steering wheel in the opposite direction or step on the brake pedal in panic when a flat tire occurs. Try to use the method of "grabbing gear" and use the clamping effect of the engine (commonly known as engine braking) to slow down the vehicle; Before the speed is not controlled, don't risk parking with the service brake, so as not to cause greater danger of vehicle side throwing.

Emergency treatment of brake failure

When driving in summer, braking failure and failure often occur suddenly due to air resistance or brake pipeline rupture or insufficient brake fluid and air pressure, which poses a threat to driving safety. When the driver finds that the vehicle suddenly fails to brake, he should keep calm, hold the steering wheel tightly, immediately release the accelerator pedal, implement engine drag braking, and avoid obstacles as much as possible by steering; At the same time, try to use parking brake or "grab gear" to slow down and stop; If the vehicle is hydraulically braked, the brake pedal can be pressed for many times continuously to accumulate braking force and produce braking effect. When using the parking brake, you can't tighten the operating lever once, which will easily "lock" the parking brake disc, damage the transmission parts and lose the braking force.

Emergency treatment of steering failure

When the steering suddenly loses control, the driver must not panic, calmly judge the degree of danger and take emergency measures to avoid the danger from getting worse. If the vehicle and the road ahead are allowed to keep straight, emergency braking should not be used. You should immediately release the accelerator pedal, grab the gear to slow down, and tighten the parking brake evenly and forcefully to assist. When the vehicle speed drops obviously, lightly step on the brake pedal and stop slowly and smoothly. When the vehicle has deviated from the straight driving direction and the accident is inevitable, the brake pedal should be pressed decisively and continuously, so that the vehicle can slow down and stop as soon as possible, shorten the parking distance as much as possible and reduce the impact. When emergency measures are taken, warning signals can be sent to other vehicles and pedestrians on the road, such as turning on danger warning lights, turning on headlights, honking horns or gesturing.

Key points of safe driving on mountain roads

In summer, the speed of driving on mountain roads should be strictly controlled, especially on curves and steep slopes. The braking function of the engine should be fully utilized to control the speed, and neutral sliding and emergency braking are strictly prohibited. When going downhill, always pay attention to the working efficiency of the brakes. Pneumatic braking vehicles should always observe the readings of barometer, and hydraulic braking vehicles should prevent "air resistance"; If you feel that the pedal is "weak" or abnormal, you should stop and check it in time. When the truck is driving on a long downhill section, it should choose a safe place to stop and rest after a certain distance to reduce the temperature of the hub.

Driver's diet and rest

Drivers should maintain a healthy daily life and pay attention to a balanced diet in summer; Don't overeat or overeat, pay attention to the reasonable collocation of food types, and form the habit of regular eating. After work, you can choose different ways to exercise and strengthen your physique; When driving a vehicle in summer, you should pay attention to the combination of work and rest, try to keep a rest time of 8 hours every day, and don't drive for too long every day. When driving, try to keep the air in the cab smooth, the temperature and humidity appropriate, effectively control emotions, maintain a good mood and concentration, observe and analyze the situation sensitively, decisively and predictably, and drive safely and happily. When you are tired of driving, you should choose to park in a safe place. If you get on the expressway, you should leave expressway at the next exit or stop at the service area.

Protect the safety of passengers.

When driving in summer, the bus driver should pay attention to keep the car clean, hygienic and fresh air, and be equipped with appropriate daily necessities and heatstroke prevention and cooling supplies to ensure that all fire-fighting equipment and facilities on the car are complete and effective, and provide a good riding environment for passengers.

Before driving, assist the flight attendants to organize passengers to get on the bus, maintain the order of boarding, remind passengers to abide by relevant regulations, and don't stick their hands and heads out of the window. After the passengers get on the bus and sit firmly, make sure the doors are closed, carefully observe the situation on both sides and the rear of the car, and start slowly.

During driving, pay close attention to the traffic situation ahead as much as possible, adjust the driving route and speed in time, find all kinds of unsafe factors in advance, calmly deal with all kinds of sudden traffic dynamics, avoid braking too fast or accelerating too fast, and ensure the smooth driving of vehicles.

When an illegal act of public security that infringes on the personal and property safety of passengers occurs during driving, it shall report to the public security organ in time and cooperate with the public security organ to terminate the illegal act of public security in time.

When a vehicle breaks down or has a traffic accident, take immediate emergency measures to protect the scene, let passengers get off as soon as possible, stand on the side far away from passing vehicles, and move the vehicle to the right side of the road or as far away from the road as possible to allow parking. Passengers or other personnel are not allowed to stay in the car or stand around the car at the scene of the accident, and they are not allowed to walk around the scene of the accident at will to prevent secondary accidents at the same place; And promptly report to the police or notify the relevant departments to rescue the wounded, collect the required information and report the accident.

Avoid occupying the road.

Driving vehicles for a long time or occupying other lanes in summer will seriously disrupt the orderly traffic flow, and vehicles will brake frequently, which will directly affect the smooth flow of roads. When driving, it encroaches on the driving route of the other vehicle, making the lateral distance of passing vehicles smaller and prone to scraping accidents. Driving in one-way lane for a long time will hinder the normal driving of vehicles in the same direction, make the rear vehicles unable to overtake normally and cause road congestion. Traffic jams in the scorching sun will affect drivers' mood and increase the probability of traffic accidents.
