Highway interval speed measurement allows exceeding the speed limit by 10%. No penalty will be imposed for exceeding the speed limit within 10% on highway intervals. Relevant introduction about highway interval speed measurement is as follows: Introduction to highway interval speed measurement: The so-called interval speed measurement refers to the method of detecting the average speed of motor vehicles passing through the road section (speed measurement interval) between two adjacent speed measurement monitoring points. For example, the speed limit range of a certain highway section is 10 kilometers, and the speed limit of this section is 120 kilometers per hour. If the vehicle travels for 5 minutes or more, its average speed will be lower than 120 kilometers per hour, meeting the speed limit requirements. Precautions for driving with interval speed measurement: Check the vehicle condition before driving and plan in advance, fasten the seat belt after getting on the car, drive according to the lane speed limit on the highway, maintain a safe distance between vehicles, drive into the nearest service area to rest when tired, and avoid fatigue driving.

Regarding highway section speed monitoring, based on my experience, don't even think about exceeding the limit. The speed limit, say 120 kilometers per hour, is a rigorously tested safe speed. Even a slight overspeed increases braking distance and accident probability. Section speed monitoring calculates the average speed over the entire stretch, not instantaneous speed, so a temporary burst of acceleration won't help you evade it. The system usually has a 10% tolerance, meaning you might get a warning without penalty up to 132 km/h, but this doesn't mean speeding is encouraged. We should develop the habit of using cruise control to maintain a steady speed, which saves fuel, ensures safety, and avoids fines and accident risks. After all, every increase in speed reduces reaction time, posing a threat to pedestrians and other vehicles, especially dangerous on highways. Don't gamble with lives.

Can a single tire be modified into dual tires?

Single tires cannot be modified into dual tires. Tire replacement time: It is recommended to replace tires every four years, even if the mileage driven within four years is relatively low. Tires are rubber products, and rubber products will age over time with prolonged use. Tire selection: When purchasing tires, be sure to check the specifications and model clearly, as well as the production date, speed rating, and load index. Generally, the sidewalls of tires for family cars or SUVs are marked with 91V. After reinstalling tires, it is essential to perform dynamic balancing to prevent abnormal vibrations during high-speed driving.

How Long Does It Take to Drive 300 Kilometers on the Highway?

Driving 300 kilometers on the highway takes approximately 3 hours. Precautions for high-speed driving: Pay attention to driving speed. On the highway, slower is not necessarily safer. A speed of 80 to 100 kilometers per hour is relatively safe for small vehicles. When exiting the highway, be sure to identify the correct exit. If you miss an exit, continue driving and exit at the next available one. Never reverse or make a U-turn. Requirements for driving on the highway: If a driver is within the probationary period, they must be accompanied by a driver who has held a driver's license for the same or a higher vehicle class for at least three years when driving on the highway. For drivers of small automatic transmission vehicles designed for disabled individuals, they may be accompanied by a driver who holds a license for small automatic transmission passenger vehicles or higher.

How to Turn on the Hazard Lights?

The hazard light switch is a red triangle symbol. Press it once to turn on the hazard lights. Introduction to hazard lights: Hazard lights, also commonly referred to as emergency flashers, are a signal light on a vehicle. Their main purpose is to alert other drivers and pedestrians that the vehicle is experiencing a special situation, prompting them to yield or avoid it in time. Usage scenarios for hazard lights: As a signal light, the use of hazard lights is strictly regulated. Misuse or failure to use them may result in fines. Therefore, it is essential to understand when hazard lights should be turned on and when they should not. The usage of hazard lights can be summarized in one sentence: if you need other vehicles to slow down or even stop to yield while driving, you should turn on the hazard lights.

Should You Turn the Steering Wheel Towards the Wider Side When Reversing into a Parking Space?

When reversing into a parking space, you should turn the steering wheel towards the wider side. Overview of Reversing into a Parking Space: Reversing into a parking space has been a mandatory test item for obtaining a small car driver's license since 2013. It assesses the driver's ability to maneuver the vehicle in a confined space. This is one of the key evaluation points in the driver's test, requiring the driver to correctly reverse the vehicle into a garage from both sides while in motion. There is a time limit for this maneuver during the test. Methods for Reversing into a Parking Space: There are three most common types of reversing into a parking space. The first is the "non"-shaped reverse parking, commonly found in large shopping malls. The second is the roadside "one"-shaped reverse parking, also known as parallel parking. The third is the less common diagonal reverse parking. About 70% of driving students find parallel parking more challenging.

Is It Illegal to Drive on the Emergency Lane?

Driving on the emergency lane is illegal. Occupying the emergency lane, once caught on camera, will result in a 6-point deduction from the driver's license and a fine. If traffic control is in place and the emergency lane is forcibly occupied, the offender may also face detention for up to 15 days. Definition of the Emergency Lane: The emergency lane is designated for vehicles with genuine "privileges." These privileges are not for the convenience of official vehicles but are specifically reserved for vehicles handling emergency situations, such as engineering rescue, firefighting and rescue, medical ambulances, or police officers performing urgent official duties. Penalty Regulations: Driving on the highway emergency lane is not explicitly detailed in the "Road Traffic Safety Law of the People's Republic of China." However, Article 90 stipulates that motor vehicle drivers violating road traffic safety laws and regulations regarding road usage will be penalized with a 6-point deduction and a fine. Therefore, the emergency lane should not be occupied under non-emergency circumstances.

How to Turn on the Car Heater for Defogging?

To defog using the car heater, turn on the air conditioning's warm air and wait for it to dry the fog on the windshield. It's important to note that you should not use hot air for defogging while driving. Initially, turning on the hot air may not only fail to remove the fog but could also worsen the fogging on the windshield, significantly increasing safety hazards. Air conditioning can adjust temperature: This is the primary function of car air conditioning. In summer, the cooling system produces cold air to lower the temperature inside the cabin. In winter, except for large commercial vehicles that use independent combustion heaters for warmth, other vehicles mainly utilize the car's residual heat for heating. Air conditioning can adjust humidity: Humidity greatly affects the comfort of passengers inside the car. The humidity inside the cabin should generally be maintained between 30% to 70%. Standard car air conditioning systems do not have the capability to adjust cabin humidity. This can only be achieved by using ventilation systems or the advanced integrated heating and cooling systems found in luxury vehicles. Air conditioning can adjust airflow: The speed and direction of airflow significantly impact passenger comfort. If the air is blowing directly, the speed should be limited to a certain range when the temperature is appropriate. The airflow speed can be adjusted based on passengers' living environment, age, health condition, and temperature preferences.
