Position lights, also known as marker lights, will only illuminate when turned on. These lights automatically activate whenever the vehicle's headlights are turned on. Located at the rear of the car, small vehicles typically have one on each side (red in color), while larger vehicles may have several on each side. They are designed to turn on when it's not completely dark outside, indicating the vehicle's width to oncoming and following traffic. Position lights help other drivers judge the size and width of the vehicle ahead during dusk or low-light conditions. Situations when position lights are illuminated: 1. Linked activation: Position lights are interconnected with the headlights. In small vehicles, they are located at the rear. Whenever the headlights are turned on (whether low beam or high beam), the position lights will automatically illuminate without manual intervention. 2. Automatic activation: Position lights don't require driver operation. At night when it's dark and the headlights are turned on, the position lights will naturally light up. 3. Purpose of position lights: Primarily to indicate the presence and approximate width of the vehicle, assisting other vehicles in making judgments during passing or overtaking maneuvers.

Can a temporary ID card be used for the subject 4 test?

A temporary ID card can be used as long as it is within the validity period. A temporary ID card has the same legal effect as a regular ID card. In some places, you can take the subject 4 test by providing your ID number, household registration book, or residence permit. However, specific details should be confirmed with the local vehicle management office, as not all places allow this. Below are the steps to apply for a temporary ID card: 1. Apply at the local police station where your permanent residence is registered. Submit your household registration book, a recent one-inch black-and-white photo (photo size standard is the same as for a regular ID card), and pay a processing fee of 10 RMB. For citizens under 16 years old, a guardian must apply on their behalf. 2. The public security authority will issue the temporary ID card within 3 days of receiving the application.

Is it no longer necessary to display the compulsory insurance decal?

If you possess an electronic compulsory traffic insurance policy, there is no need to display the compulsory insurance decal. Here are the details: 1. Electronic Policy: Electronic policies hold the same validity as physical policies and decals. If stopped by traffic police, the vehicle owner can simply present the electronic policy for clearance without facing fines or towing. Cities like Beijing and Shenzhen have pioneered the electronic policy system, where traffic police can verify insurance coverage through online databases, eliminating the need for window decals. 2. Electronic Policy Verification: Electronic compulsory insurance policies are now implemented nationwide, so vehicle owners traveling to other provinces without displaying the decal will not encounter issues. Local traffic police departments can access the electronic policy information through shared platforms using the license plate number. As long as the information matches, out-of-province officers will not impose fines or deduct points for missing decals.

How Long Can an Electric Vehicle Last on a Single Charge?

Electric bicycles can generally travel about 60 kilometers; pure electric vehicles can travel about 100 kilometers. Common battery capacities for electric vehicles include 12Ah, 20Ah, and 32Ah. It is best to charge an electric vehicle battery with a matching voltage. For example, a 48V battery should be charged with a 48V charger, not a 60V charger. Lead-acid batteries are prone to swelling when overcharged, while lithium batteries are prone to explosion. Below are some precautions for charging electric vehicles: 1. For the first charge, discharge the battery before charging. 2. Avoid overcharging. 3. Do not drain the battery completely before charging. The optimal time to charge is when the remaining battery level is at 20% (when the dashboard shows the last two bars). Even if you forget for a few days, the battery won’t be damaged to the point of being unusable. 4. The charging time should be determined based on the battery capacity and remaining charge.

How to Check the Engine Oil Level?

Car engine oil level is primarily checked using the oil dipstick. Here is a detailed explanation of how to check the engine oil: 1. Park the car on level ground: Regardless of the shape of the engine oil pan, the position of the oil dipstick remains constant, meaning it measures the oil level at a fixed location. The car must be parked on a flat surface as specified to obtain an accurate measurement. 2. Using the oil dipstick: Always insert the oil dipstick all the way in. The oil level should be between the upper and lower marks on the dipstick to ensure proper operation of the engine and related components. A few minutes after turning off the engine, although most of the oil has drained back into the oil pan, oil splashed by the crankshaft may still cling to the dipstick, potentially causing misreading. 3. Identify the correct dipstick: In some car models, there are two dipsticks in the engine compartment—one for engine oil and another for transmission fluid. Make sure to identify which one is the actual engine oil dipstick.

What Are the Disadvantages of Pure Electric Vehicles?

Pure electric vehicles have the following disadvantages: 1. Charging Difficulty: In the context of lagging charging infrastructure construction in China, charging is a major challenge for electric vehicles. The lack of public charging piles severely impacts the mobility of electric vehicles. 2. Short Driving Range: Limited by battery capacity, most pure electric vehicles currently have a driving range of only 100-200 kilometers. Although experts repeatedly claim that 90% of people drive less than 50 kilometers daily, Chinese consumers have higher range requirements than Americans. This is because few Chinese families own more than one car, whereas Americans can use one pure electric vehicle for commuting and a traditional car for travel. 3. Slow Charging: Currently, most charging piles are slow chargers, taking 5-8 hours to fully charge a vehicle. While overnight charging during rest periods is possible, the drawback of slow charging becomes evident in case of emergencies. 4. After-Sales Service Needs Improvement: Although the structure of electric vehicles is simpler, the powertrain differs significantly from traditional cars, leading to some repair challenges. The first issue is the shortage of skilled technicians. Most technicians today can repair traditional cars but lack knowledge in electrical systems. Attempting to repair electric vehicles without proper expertise may not only damage the vehicle but also pose certain risks. The second issue is the scarcity of spare parts. Due to the low production and ownership of electric vehicles, spare parts are limited and expensive.
