Will speed cameras be active in a 70 km/h construction zone on the highway?

Speed cameras will be active in a 70 km/h construction zone on the highway. Below is an introduction to speed limits for two-lane and three-lane highways: 1. Two-lane highways: For highways with two lanes in the same direction, the speed range for the right lane is 60 to 100 km/h, while the left lane allows speeds from 100 to 120 km/h. 2. Three-lane highways: For highways with three lanes in the same direction, the speed range for the far-right lane is 60 to 90 km/h, the middle lane is 90 to 110 km/h, and the far-left lane is 110 to 120 km/h. The left lane is designated for overtaking, hence it has higher speed limits.

From driving experience, the speed limit of 70 km/h in highway construction zones is almost always enforced. I've seen too many fellow drivers get caught in such areas. Construction zones are usually equipped with mobile speed cameras or temporary surveillance, as traffic police are concerned about speeding causing accidents. After all, the lanes are narrowed and there are construction vehicles coming in and out, making it highly dangerous. Once when I was driving at night through a construction zone in Jiangsu, I saw the speed limit sign but still took a chance driving at 80 km/h, only to receive a ticket the following week. Now whenever I encounter a construction zone, I strictly adhere to the speed limit—safety first and peace of mind. It's advisable to install a radar detector for early warnings, but the most important thing is to consciously obey the speed limit.

I have personal experience with this—just last week, I was caught speeding in a construction zone on the Hu-Shan Expressway. The speed limits in construction areas are there for a reason: the road surface is uneven, lanes narrow, and conditions are far more complex than usual. Traffic authorities often deploy portable radar speed traps in work zones, and sometimes police cars hide behind construction barriers to catch violators. Don’t think 70 km/h is too slow—these limits are carefully calculated. A speeding ticket is minor compared to the risk of hitting a traffic cone or a worker. With expressways now under networked surveillance, there’s no escaping a speeding record—don’t count on luck.

Chances are high you'll get caught. Highway construction zones are usually equipped with temporary speed monitoring devices. A friend who works in maintenance told me this is standard procedure. The 70 km/h speed limit in work zones is strictly enforced, and traffic police often place portable radar units in diversion areas. Once when I entered a construction zone with maintenance vehicles, I witnessed them setting up speed cameras - even mobile speed detection vehicles have camouflage paint. A speeding ticket would be the least of your worries; with numerous obstacles in work zones, hitting something as simple as a reflective traffic cone could trigger a chain-reaction accident. Better safe than sorry - sticking to 70 km/h is the wisest choice.

As a veteran truck driver with over 20 years of experience, I strongly advise against taking risks. The speed cameras in highway construction zones are like having eyes everywhere - our fleet learned this the hard way. Especially in detour sections, speed monitoring equipment is definitely watching. I remember one year when the Jingha Highway was under construction, hundreds of speeding vehicles were caught within just three days. Nowadays, the new portable speed detectors are so compact they can be hidden behind construction barriers, completely invisible. Rather than worrying about getting caught, think about safety: narrowed lanes, diverted routes, and construction machinery moving about - speeding here is literally playing with your life. And if an accident happens, insurance won't cover speeding violations anyway.

The likelihood of getting caught is quite high. Once, I hitched a ride with an engineering expert through a construction zone, and he pointed at those temporary supports, saying they were speed measurement devices. Construction zones have a high risk of accidents, so traffic authorities monitor them closely. It's common to see mobile speed cameras stationed in diversion lanes or disguised near construction machinery. A speed limit of 70 km/h might seem slow, but considering the potential sudden appearance of potholes or detour signs, this speed isn't overly cautious. Not only could you get a ticket for speeding, but if there's a protruding steel bar on the road, passing at high speed could easily cause a tire blowout.
