The reasons for inaccurate fuel gauge readings in cars are: 1. The fuel pump cannot uniformly reflect gasoline consumption; 2. The fuel level sensor becomes contaminated and isn't cleaned promptly; 3. The linkage between the fuel level sensor and float gets stuck, preventing normal float movement. Precautions when refueling include: 1. Don't wait until the warning light comes on to avoid extremely low fuel levels; 2. Choose to refuel during cooler morning or evening temperatures; 3. Avoid completely filling the tank during city driving to prevent spark plug failures caused by fuel overflow; 4. Don't refuel during thunderstorms to prevent stray currents from the fuel nozzle entering the fuel tank, which could create fire or explosion hazards.

Can I Wear Color Blind Glasses for Driver's License Renewal?

You can wear color blind glasses during the driver's license physical examination, but whether you can pass the exam depends on the results of the relevant tests. If wearing color blind glasses allows you to accurately identify the color blindness test cards, the examiner will determine whether you pass. However, if you still cannot correctly identify the color blindness test cards while wearing the glasses, you will not pass the physical examination and will not be eligible to obtain a driver's license. According to Article 11 of the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," the physical examination items for learning to drive include: Height: Applicants for large buses, tractors, city buses, large trucks, or trolleybuses must be at least 155 cm tall. Applicants for medium-sized buses must be at least 150 cm tall. This is the first step in the physical examination for learning to drive. Vision: For applicants of large buses, tractors, city buses, medium-sized buses, large trucks, trolleybuses, or trams, the naked or corrected vision of both eyes must reach at least 5.0 on the logarithmic visual acuity chart. For other vehicle types, the naked or corrected vision of both eyes must reach at least 4.9 on the logarithmic visual acuity chart. Color Vision: No red-green color blindness. This is consistent with the vision requirements in the physical examination for learning to drive. Hearing: Able to distinguish the direction of sound sources with each ear at a distance of 50 cm from a tuning fork. Upper Limbs: Both thumbs must be intact, and each hand must have at least three other fingers intact, with normal limb and finger movement functions. Lower Limbs: Normal movement function. Applicants for manual transmission vehicles must have lower limbs no longer than 5 cm. Applicants for automatic transmission vehicles must have a sound right lower limb. Torso and Neck: No movement dysfunction.

How to Install ETC on a Private Car?

ETC can be processed at bank branches or highway service areas. After installing the ETC device at the service point, professional staff will assist with the installation. Required documents include the vehicle owner's valid ID card and the original and photocopy of the vehicle registration certificate. If the application is not processed by the owner, the agent must also provide their valid ID card. The photocopy of the vehicle registration certificate must include the page with the most recent annual inspection stamp. Additionally, a Postal Savings credit card application form is required, as the credit card will be used to bind the ETC card. After receiving the credit card, swipe it twice and present the POS slip to claim and install the ETC onboard device for free at designated Postal Savings branches, with no additional charges. Applicants must be between 18 and 60 years old and own the vehicle in their name. ETC stands for Electronic Toll Collection, meaning electronic toll system. Below are some considerations for installing ETC: Do not obstruct the driver's view. It is best to install it behind the rearview mirror: Many car models have steeply angled windshields, which can reduce the driver's field of vision. Installing the ETC without considering this may increase blind spots. Installing it on the right side behind the rearview mirror avoids obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a built-in solar panel on the back for self-charging. Therefore, avoid installing it on the blackened areas of the windshield or where the solar panel might be blocked. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After installation, the windshield presses the lever in. If removed, the lever will pop out, triggering the switch and locking the electronic tag, rendering it unusable. You will then need to visit an ETC service point to unlock it. This mechanism prevents multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid paying for the vehicle in front due to its faulty ETC device, maintain a distance of at least 10 meters. The ETC lane recognizes vehicles at speeds up to 20 km/h; exceeding this speed may result in failed transactions due to unreadable device information. If using a debit card linked to ETC, insufficient balance may also cause transaction failure.
