Class 1 vehicles include sedans and small passenger vehicles with 7 seats or fewer, as well as small trucks with a weight of 2 tons or less. In addition to Class 1 vehicles, there are also Class 2, Class 3, Class 4, and Class 5 vehicles. Class 2 vehicles consist of passenger vehicles with 8 to 19 seats and trucks weighing more than 2 tons up to 5 tons (inclusive). Class 3 vehicles include passenger vehicles with 20 to 39 seats, trucks weighing more than 5 tons up to 10 tons (inclusive), and 20-foot container trucks. Class 4 vehicles comprise passenger vehicles with 40 seats or more, trucks weighing more than 10 tons up to 15 tons (inclusive), and 40-foot container trucks. Class 5 vehicles are trucks weighing more than 15 tons. Apart from the above classifications, vehicles can also be categorized based on the method of measuring the vehicle's front height, which is measured vertically from the ground upward at the position of the front axle. Class 1 vehicles have a front height of less than 1.3m, such as sedans, jeeps, and motorcycles. Class 2 vehicles have a front height of 1.3m or more, such as small trucks, light trucks, and small passenger vehicles.

I've always thought that Class 1 vehicles refer to the small passenger cars commonly used by ordinary families, such as sedans or compact SUVs, which belong to this category. The seating capacity should not exceed 9, and the total vehicle mass is generally kept within 3,500 kilograms. I've been driving this type of car for many years, and the most obvious advantage is the low toll fees on highways. For example, passing through a toll station usually costs just a few dozen yuan, whereas buses or large trucks have to pay much more. Additionally, these cars are convenient for daily use, easy to park, fuel-efficient, and highly maneuverable, making them ideal for navigating city streets. However, it's important to avoid unauthorized modifications or overloading, as exceeding the weight limit might result in reclassification to a Class 2 vehicle, leading to higher fees and fines. Insurance and annual inspections for these vehicles are relatively straightforward and less expensive, making them suitable for those on a tight budget. With population growth, small cars are becoming increasingly popular, and Class 1 vehicles have become the dominant model on the road.

When chatting about cars with friends, the concept of "Class I vehicles" often comes up. It specifically refers to small passenger vehicles with no more than 9 seats, such as common sedans and MPVs. From a car culture perspective, these vehicles are flexible and versatile, offering great potential for modifications. On the policy front, emission requirements are relatively lenient due to their smaller size and lower pollution levels. They also save money on highway tolls, making them ideal for young people or those just entering the workforce as daily commuters—models like Haval or Toyota’s compact cars are typical examples. However, before purchasing, it’s essential to confirm the specifications to avoid mistakenly opting for a larger vehicle that falls into Class II, which would add extra costs. In terms of usage, urban traffic restrictions are more lenient for Class I vehicles—for instance, they might face one fewer day of plate-based driving bans per week, enhancing commuting convenience. In short, understanding this classification can help save money and hassle.

The definition of Class I vehicles originates from the history of China's automotive development. As early as the 1980s and 1990s, with the advancement of economic reforms, vehicle classification was standardized, designating Class I vehicles as small passenger cars—specifically those with no more than 9 seats. Prior to this, vehicle management was chaotic and distinctions were unclear. The current clear classification facilitates toll collection and the enforcement of environmental standards. Small cars, as the main body of Class I vehicles, have become market leaders due to the popularity of energy-saving and environmentally friendly concepts. When purchasing a car, referencing this history can help avoid buying vehicles with confusing classifications, such as early simple sedan designs compared to today's diverse SUVs. Understanding the evolution of classifications enables more informed car selection.
