How many points will be deducted for driving on the highway with a license obtained within half a year?

Driving on the highway with a license obtained within half a year requires an accompanying driver and will not result in point deduction. Relevant regulations: Article 75, Paragraph 2: A driver who operates a motor vehicle on a highway during the probationary period must be accompanied by a driver who has held a driver's license for the corresponding or higher vehicle category for more than three years. For drivers of small automatic transmission passenger vehicles for the disabled, they may be accompanied by a driver who holds a driver's license for small automatic transmission passenger vehicles or higher. During the probationary period after adding a new vehicle category, the above restrictions do not apply when driving the original vehicle category. Highway driving precautions: When driving on the highway and missing an exit due to unfamiliarity with the road, never reverse, drive in the opposite direction, or make an emergency stop. The correct approach after missing an exit is to proceed to the next exit, leave the highway, and then return. Avoid causing unnecessary traffic accidents by trying to save time.

Where is the PCV one-way valve located on the Wuling Rongguang?

The PCV one-way valve on the Wuling Rongguang is generally installed on the valve cover (or nearby) or the connected intake pipe. The automotive PCV valve is a forced ventilation device inside the vehicle's crankcase, composed of components such as the valve body, valve, valve cover, and spring. The crankcase ventilation system is also known as the "PCV system" or exhaust gas recirculation system. The function of the automotive PCV valve is to regulate the amount of oil vapor entering the intake system caused by the crankcase ventilation system. Additionally, in the event of engine backfire, it can immediately cut off ventilation to prevent issues such as crankcase explosions. Effects of a faulty automotive PCV valve on the vehicle: Engine vibration: The engine may shake during operation, with unstable idling, and a large amount of white smoke may emerge from the exhaust pipe. Causes internal crankcase corrosion: A faulty PCV valve can affect the inside of the crankcase, leading to corrosion and accelerated wear, further reducing the engine's lifespan. Poor vehicle acceleration: The engine may become difficult to start and exhibit poor acceleration. Air filter contamination and damage: A damaged PCV valve can also lead to sludge buildup, which is prone to sedimentation and blockage. The blockage increases crankcase pressure, causing oil vapor to flow back into the air filter and ultimately contaminating and damaging it.

How to Apply for ETC for Motorcycles?

Motorcycles cannot apply for ETC. Where can ETC be installed: For small vehicles such as cars and minivans, the OBU device is installed in the upper middle part of the front windshield, while for large vehicles like trucks and buses, it is installed in the lower middle part. ETC installation position requirements: the height should not be less than 1.2 meters or more than 2.5 meters; the installation angle N should be between 30º and 90º (the angle between the surface of the electronic tag and the horizontal plane). The ETC installation process is as follows: Upon receiving the device, first check whether the ETC card and the electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly turn on. The OLED screen will display "Tag Invalid" or "Please Insert Card," indicating that the device is functioning properly. Clean the front windshield to ensure the surface is smooth, clean, and dry. Then peel off the adhesive backing film of the OBU and stick it to the installation position. Press firmly with your hand for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front side facing the driver and the back side facing the windshield, ensuring the chip is inserted into the OBU device.
