China IV vehicles are restricted in Beijing and require a Beijing Entry Permit. Below are detailed explanations about the China IV standard: 1. Overview: The China IV emission standard is the national fourth-stage motor vehicle pollutant emission standard. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), PM (particulate matter), etc. 2. Others: The China IV emission standard applies technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices to control and reduce vehicle emissions below specified limits.

As a veteran Beijing driver with over a decade of experience driving China IV emission standard vehicles, let me tell you the truth - China IV gasoline passenger cars can still operate in Beijing, but with more restrictions. During weekday rush hours, they're subject to the odd-even license plate rule. Main thoroughfares like Chang'an Avenue prohibit them during daytime, and key areas such as the 2nd Ring Road main route must be avoided. Out-of-town plated China IV vehicles face even tighter controls, only permitted to operate outside the 6th Ring Road even with Beijing entry permits. Diesel vehicles have it worst - completely banned within the 6th Ring Road. My car still holds up fine though; I just switch to subway commuting during peak hours and use it for weekend suburban trips without issues. For frequent urban driving, I'd recommend considering new energy vehicles or China VI standard cars instead.

All of us in the freight business know that National IV diesel trucks simply can't operate in the capital. Last year, the policies got even stricter - they're completely banned from entering within the Sixth Ring Road 24/7, and even temporary passes aren't approved anymore. My colleague's National IV light truck is now stuck doing in Shunyi every day, and even going to Changping is nerve-wracking. Gasoline cars fare slightly better, but they still face traffic restrictions during rush hours, with additional controls in key areas like Tongzhou. The worst is when smog hits - you never know when they'll suddenly impose extra restrictions. If you're thinking about changing vehicles, go straight for a National VI diesel or pure electric truck. They're more expensive, but save you a lot of headaches.

When I inquired at the Haidian Vehicle Office, I learned that National IV vehicles can currently operate in Beijing. Local gasoline vehicles just need to pass the annual inspection as usual, but they must avoid driving during peak hours due to the tail number restriction. However, it's more troublesome for out-of-town license plates. Last year, my cousin from Hebei came to visit with his National IV vehicle, and he was directly denied the entry permit for areas within the Sixth Ring Road. In the end, he had to leave his car in Fangshan and take the subway into the city. Diesel trucks have it even worse—they're not even allowed inside the Sixth Ring Road. It feels like policy tightening is inevitable, and now it seems only National V or above vehicles are truly worry-free.

There are quite a few neighbors in Huilongguan driving China IV emission standard vehicles, after all, it's right by the Sixth Ring Road. Daily tasks like picking up kids or grocery shopping are no problem, and for weekend trips into the city, they take the subway. My neighbor Old Zhang's China IV Passat has been running fine for eight years—it still gets him where he needs to go, just avoiding rush hours. However, out-of-town visitors should note: their China IV cars couldn't drive directly into the neighborhood during the last two Spring Festivals, having to park outside the Fifth Ring and transfer. Long-term, upgrading makes sense—a friend in Xicheng switched to a hybrid last year.

Environmental protection policies have become increasingly stringent in recent years. In Beijing, the restrictions on National IV vehicles mainly fall into two categories: gasoline vehicles are subject to weekday tail number restrictions and key area controls, while diesel trucks are prohibited from entering within the Sixth Ring Road at all times. The underlying logic is clear—under the pressure of PM2.5 control, high-emission vehicles are inevitably restricted. Data from monitoring stations in Chaoyang District show that pollutant emissions from National IV vehicles can be more than four times higher than those from National VI vehicles. With the National VII standard in the pipeline, restricted areas may expand to within the Fifth Ring Road in the future. When choosing a car now, it's best to prioritize National VI or new energy vehicles for a longer usage cycle.
