Can National 5 still be used after National 6 is implemented?

After the implementation of National 6, National 5 vehicles can still be driven, but they cannot be registered in some regions. The following are solutions for National 5 vehicles that cannot be registered and an introduction to the National 5 standard: Solutions for National 5 vehicles that cannot be registered: Return the National 5 vehicle to the factory for modification. The manufacturer can replace some parts of the vehicle to meet the National 6 standard, after which it can still be driven on the road. Alternatively, registering the National 5 model in advance allows it to be driven legally. However, a new car will become a so-called used car after registration, facing severe depreciation even if it has never been driven. Introduction to the National 5 standard: The National 5 standard is equivalent to the EU's Euro 5 standard, which has been in effect since 2009. It imposes stricter limits on nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter emissions from motor vehicles.

What is the Optimal Tire Pressure for Fuel Efficiency?

Tire pressure and fuel consumption are inversely proportional—higher tire pressure leads to lower fuel consumption. However, as tire pressure decreases, the rate of increase in fuel consumption becomes more gradual. In practical experience, a range of 2.4-2.6 Bar is optimal. Fuel efficiency still largely depends on individual driving habits. 1. If the car is fully occupied (5 people), adjusting the tire pressure to around 2.5 Bar is advisable; for two passengers, a tire pressure of 2.3 Bar is also normal. 2. Standard tire pressure can usually be found in the following locations: 3. The vehicle's user manual, the label near the driver's door (B-pillar), the drawer next to the driver's seat, or the fuel tank cap door.

What are the violations that result in a 12-point deduction at once?

1. Driving a motor vehicle that does not match the permitted driving category; 2. Driving under the influence of alcohol or driving a commercial motor vehicle after drinking; 3. Driving a highway passenger vehicle with more than 20% over the approved number of passengers; 4. Fleeing the scene after causing a traffic accident, which does not constitute a crime. What are the common traffic violations that result in a 6-point deduction at once? Running a red light is the most common violation. Since the new traffic regulations were introduced, running a red light results in a 6-point deduction. It is reminded to car owners that if you run a red light twice within a scoring cycle, you will be deducted 12 points. If you do not restrain yourself, it means your driver's license will be at risk. This issue is quite serious and requires the high attention of car owners.

How to Distinguish Which Version a Car Belongs To?

The high, mid, and low trim levels of the same car model generally do not differ much in overall layout. Their differences are often reflected in various configurations. If you pay attention, it's relatively easy to distinguish between high, mid, and low trim levels. Sunroof: Typically, the premium version (high trim) comes with a sunroof, while the low trim does not. Headlights: Low trim models usually feature halogen headlights, whereas high trim models may have xenon or LED headlights. Some cars also differ in fog lights, with low trim models sometimes lacking them entirely. Wheels: High trim cars often have larger and more distinctive wheel designs, making them easy to identify by size. Air conditioning: Low trim models usually lack rear air vents, which high trim models include—unless the vehicle platform design excludes them altogether. Rear: You can also distinguish versions by the markings on the rear, such as "4X4" or "4WD," which typically indicate a high trim all-wheel-drive model.
