Gaogang Avenue has a speed limit of 60 km/h. Precautions for driving are as follows: 1. Vehicle inspection before departure: Conduct a comprehensive check of the vehicle every day before setting off, including checking for oil or water leaks; measure tire pressure to ensure it is appropriate; inspect the engine oil condition; verify the spare tire is intact, etc. 2. Be cautious when wading: If encountering flooded roads, be aware of the water depth and the condition of the road beneath before deciding whether it exceeds the vehicle's capability. Avoid wading if the water depth exceeds half the height of the car's tires. 3. Obey traffic rules: Especially on highways, do not speed. Speeding not only risks fines from traffic police but, more importantly, is unsafe.

















I often drive on Gaogang Avenue, and I remember the speed limits are set in sections. The part near the urban-rural fringe is relatively wide, with a speed limit of 100 km/h for small vehicles, but large trucks can only go 80 km/h. When entering the main urban road section, the speed limit drops to 80 km/h, especially in residential areas where you need to be extra careful. The most important area to watch out for is the school zone, where the speed limit drops directly to 40 km/h during morning and evening school hours. There are a lot of speed cameras there, and just last week I saw a car getting caught for speeding. Oh, and at every entrance, there are large speed limit signs—it’s safest to glance at them a few times while driving.

Last time I took the Gaogang Avenue in Taizhou with navigation on, the voice prompts were exceptionally clear: the speed limit is 100 km/h on non-urban sections and 80 km/h in urban areas. However, I noticed a detail—there are temporary speed limit signs of 70 km/h posted at some downhill curves, likely for special section controls. There aren't many fixed speed cameras on this road, but mobile speed cameras often hide behind the greenery for enforcement. It's advisable to keep your navigation on, as it provides real-time updates on speed limit changes, which is much more reliable than just relying on road signs.

Checked the latest traffic information, the speed limit on Gaogang Avenue has been adjusted several times in different sections. Currently, the maximum speed allowed on the expressway section is 100 km/h, but only for passenger cars. All trucks and buses are limited to 80 km/h at all times. There are special speed limit zones near hospitals and schools with prominent 40 km/h speed limit signs. Most importantly, the speed limit is automatically reduced during rainy or foggy weather. Driving on this road in such conditions requires extra attention to the changing speed limit signs, otherwise it's easy to exceed the speed limit.

My friend at the traffic department mentioned that the speed limit standards on Gaogang Avenue were updated in the first half of this year. Previously, the entire stretch had an 80 km/h limit, but now non-urban sections allow passenger cars to go up to 100 km/h. However, there are three hazardous spots requiring special attention: a continuous curve with an 80 km/h limit located two kilometers south of the Gangkou Road intersection, a 40 km/h limit enforced all day in front of Chungang Elementary School, and a 60 km/h limit on the highway connector ramp. These locations capture over a hundred speeding violations every month. Fines are the least concern—the main issue is the high risk of accidents.

Veteran drivers who frequent this route know that the speed limit signs on Gaogang Avenue are more reliable than navigation apps. As you approach the urban area, you'll first see a gradual reduction from 100 to 80 km/h, followed by repeated 80 km/h signs every few hundred meters. The most ticketed section is near the Port Authority, where the speed limit suddenly drops from 80 to 60 km/h, catching many drivers off guard. It's recommended for beginners to activate lane-level navigation on this road, as real-time alerts are far more timely than human observation—definitely money well spent.
