There are no explicit legal provisions prohibiting radar detectors, so they can be considered not illegal. However, some regions may prohibit their use. Reasons for prohibition: The installation and use of "radar detectors" can interfere with the normal operation of traffic monitoring equipment and the reception of signals from such devices. Therefore, for safety reasons, some regions prohibit their use. After installing radar detectors, some drivers may drive recklessly at high speeds and suddenly brake before speed detection points to evade monitoring, which is clearly detrimental to safe driving. This behavior can easily lead to unnecessary traffic accidents, as sudden braking may cause following vehicles to fail to react in time, resulting in rear-end collisions. This is also why some regions do not allow the use of radar detectors. Introduction to radar detectors: With the strengthening of traffic monitoring measures, many private car owners have purchased radar detectors or GPS navigation devices with electronic eye detection functions to reduce the number of traffic tickets. The main purpose of radar detectors is to alert drivers in advance to the presence of electronic eyes or speed detection radars, allowing them to prepare accordingly to avoid fines and penalty points for speeding or violations. The goal of radar detectors is to prevent drivers from being caught and fined by traffic cameras for speeding. However, as long as drivers comply with traffic laws and drive safely, there is no need to use radar detectors at all.

As a car enthusiast, I used to pay close attention to radar detector devices, but since 2021, Chinese traffic regulations have strictly prohibited the installation or use of any form of radar detectors or jamming equipment. The law explicitly states that such tools interfere with normal law enforcement and threaten road safety. I remember one time my friend used one on the highway and was caught by traffic police, resulting in an immediate fine and penalty points. Nowadays, with so many smart traffic cameras, these devices are easily detected. If you're worried about speeding, I highly recommend using navigation apps like Gaode or Baidu Maps. Their built-in radar detector features legally alert you to speed traps based on publicly available data—completely free, safe, and reliable. I use this method daily while driving, combined with regular vehicle checks, to ensure everything is by the book and avoid unnecessary trouble. Everyone must follow the rules—safe driving is more important than anything else.

As a long-time car owner, installing a radar detector is absolutely not advisable these days! Recently, traffic authorities have been cracking down hard on such devices because they interfere with camera and radar enforcement, affecting fairness. I heard that even those purchased in 2021 are now subject to penalties, with hefty fines and points deducted from your license. My advice is to simply avoid these gadgets altogether and switch to the built-in navigation system that comes with new cars—many models now have intelligent alert features. When driving on highways, make it a habit to watch for roadside signs and control your speed. With years of driving experience, I believe safety awareness comes first—don’t risk big losses for small gains. With so many road cameras, having a radar detector can actually make you uneasy. If you’re really concerned about speeding, consider installing a legitimate dash cam, which can also monitor road conditions.

How to Set Up an Aftermarket Tire Pressure Monitoring System?

The method to set up an aftermarket tire pressure monitoring system is: 1. After inflating the tires, press the SET button for 3 seconds; 2. While pressing, the dashboard light will illuminate; 3. After 3 seconds, a beep will sound, and the dashboard light will turn off, indicating completion. Aftermarket tire pressure monitors come in various types, including cigarette lighter plug-in, solar-powered, vehicle-specific, and navigation-integrated models. Tire Pressure Monitoring System (TPMS) is used to monitor tire pressure. If a tire's pressure is too low, it will alert the driver to insufficient tire pressure, preventing abnormal wear due to underinflation. When tire pressure is too high, it reduces the contact area between the tire and the ground, increasing the pressure the tire bears and affecting its grip.

Should You Press the Brake When Shifting from D to S Gear in an Automatic Transmission?

You do not need to press the brake when shifting from D to S gear in an automatic transmission. The correct usage of the S gear in an automatic transmission is as follows: 1. Use it during short-distance racing competitions; 2. Use it when driving uphill, overtaking, or on rough roads; 3. Use it when stronger traction is required. When shifting into S gear, the engine speed increases, and the transmission shifts up later and down earlier, enhancing the vehicle's power performance. An automatic transmission does not require the driver to manually shift gears; the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. The correct method for starting an automatic transmission car is: 1. Move the gear selector to the intended driving position before pressing the accelerator pedal; 2. Avoid pressing the accelerator abruptly; instead, press it slowly to gradually accelerate.
