After selling a car, if the original license plate number will continue to be used, you need to remove the ETC device and install it in the new car, then reactivate it once. If the license plate number will no longer be used, you need to cancel the original ETC device. How many ETCs can one person apply for: If a person owns only one car, they can only apply for one ETC. If a person owns multiple cars, they can apply for multiple ETCs. ETC usage precautions: The ETC transaction sensing area is 8 meters. When encountering a stationary vehicle ahead, to prevent the vehicle in front from having a faulty ETC device or no ETC device at all, maintain a distance of more than 10 meters to avoid automatic sensing and paying for the vehicle ahead. The ETC lane recognition speed is 20km/h. If the vehicle speed is too fast, the vehicle device information cannot be read, which will also result in a failed fee deduction. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will cause the electronic tag to fail. It can be sent to the bank where the ETC card was issued or the highway service office for testing. If the loosening or detachment is not caused by human factors, it only needs to be reactivated. When using a debit card to bind the ETC, insufficient balance will also result in a failed fee deduction. Follow the guidance of on-site staff to use the manual MTC lane and pass through by cash or card. An excessively thick car windshield may cause poor sensing. This is especially important for vehicles that have had their windshields replaced after an accident or for those who have modified their front windshields.

Last month, right after I sold my old car, I encountered this issue. The ETC device definitely shouldn’t be left for the new car owner—it must be removed and taken away. Remember to contact the issuing bank to complete the cancellation procedures; otherwise, if the next owner uses it on the highway, the charges will still be deducted from your account. If you’re getting a new car, you can continue using this device, but you’ll need to visit an ETC service center to reactivate and rebind it to the new license plate. A friend of mine learned this the hard way—they forgot to handle the ETC when selling their car and ended up receiving a highway toll bill of over 1,000 yuan three months later. Now, I always remove the device immediately and take a photo as proof for the buyer. Finally, make sure the bank confirms the account deactivation—the whole process usually takes about two to three days to complete.

Which lane should you take after making a U-turn?

After making a U-turn, the vehicle should take the middle lane and then move to the leftmost lane. Here is the relevant information: 1. U-turn prohibition: Motor vehicles are not allowed to make U-turns at locations with no U-turn or no left-turn signs and markings, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or sections of road prone to danger. 2. Precautions: It is prohibited to change two lanes at once. You should change lanes one by one until you reach the leftmost lane. Do not cross the solid line at intersections, and do not change lanes. The yellow grid area indicates no parking. If there is a red light ahead, vehicles behind should avoid this area.

What does it mean when the ABS warning light comes on?

ABS warning light indicates an alert in the anti-lock braking system. The ABS system may stop functioning, manifesting as reduced braking effectiveness, increased braking distance, and poorer handling performance during braking. Therefore, when the ABS light illuminates, the issue should be promptly addressed. The Anti-lock Braking System (ABS) functions by automatically regulating the braking force during vehicle deceleration to prevent wheel lock-up, maintaining a state of rolling and sliding (with a slip ratio around 20%), thereby ensuring maximum tire-to-road adhesion.

Does Stepping Hard on the Gas Pedal When Stuck Damage the Car?

Stepping hard on the gas pedal can cause significant damage to the car's engine. Here's the relevant information: 1. Reason: Normally, the engine operates through the coordinated movement of multiple components via the crankshaft connecting rod mechanism and the valve train. However, when the engine is at full throttle, it essentially runs at full speed without load, which can lead to misalignment among internal engine components. 2. Low Gear with High Throttle: If you use a low gear with high throttle, it can cause excessive friction and overheating of internal engine components, reducing lubrication and heat dissipation efficiency. The poor coordination among parts will accelerate engine wear and significantly shorten the engine's lifespan.

How to Use an Automatic Transmission Car?

Automatic transmission car usage tutorial: 1. Press the brake pedal to start the ignition switch, wait for the dashboard to display OK, then shift the gear lever to D (Drive) position; 2. Release the parking brake and accelerate - the transmission will automatically shift gears based on throttle input; 3. Operate brake or accelerator pedals according to road conditions without manual gear changes; 4. While driving, you can shift from D to N (Neutral) for coasting, but this may cause brake pedal softness and doesn't save fuel. Automatic transmission eliminates manual gear shifting - the vehicle automatically selects appropriate gears based on speed and traffic conditions. Typical automatic transmissions feature P (Park), R (Reverse), N (Neutral), D (Drive), S (Sport), and L (Low) positions.

Why Does the Horn Sound Weaker on Rainy Days?

There are several reasons why the horn sound becomes weaker on rainy days: 1. Poor internal contact: According to the working principle of the horn, if the contacts are not properly connected, the horn may sometimes work and sometimes not. In such cases, the first thing to consider is whether the contacts are wet or damp. 2. Poor plug contact: Sometimes, the contacts around the steering wheel may wear out due to frequent use, leading to poor connection. This can also cause the horn sound to become hoarse. If this happens during rainy weather, the sound may become weaker or even stop working. 3. Water damage to the crossover: Although the crossover is located inside the car, it is still important to protect it from water and moisture. If the terminals are found to be damp or even soaked, they should be dried immediately, and the door seals should be properly maintained to prevent the horn sound from weakening after rain.
