Complete Guide to Speed Limits and Section Speed Enforcement
The two things that are easiest to get fined for when self-driving in Xinjiang: sudden speed limit signs and long-distance average speed checks. Understand the rules to avoid paying unnecessary fines. A complete guide to speed limits and average speed checks is part of the Xinjiang travel preparation series: it explains practical matters such as season and duration, documents and border permits, chartering cars and transportation, payment and internet access, food and accommodation all at once, so you can check everything before departure.
Interval Speed Measurement Logic
Xinjiang highways and national/provincial roads extensively use interval speed measurement: the entry start point and exit end point calculate average speed, and there are also instantaneous speed monitoring points along the way. Don’t think you can exploit a long stop midway—service area stop time will be deducted, and long stops require receipts for verification.
Common Speed Limit Changes
G30 and G3012 highways: 120/100 km/h, national/provincial roads: 80/60 km/h, mountainous areas and towns: 40 km/h; construction zones, schools, and curved road sections often have temporary signs. Speed limit change locations usually have warning signs, which, together with navigation and electronic speed camera alerts, are more reliable.
Violation Handling
On-site law enforcement issues tickets to be paid within 15 days; electronic camera violations can be handled through "Traffic Management 12123", with the same process for out-of-town plates. For chartered tours, no need to worry; for self-driving, check for violations once before returning the car to a different location.
Safety Redundancy
Long straight roads can cause fatigue and speeding; rotate drivers in the front passenger seat to read signs. Exceeding speed by less than 10% generally results in a warning, but for desert highways that are 200 km straight, don’t gamble with safety.
