What is the speed limit in the Daguang Expressway tunnel?

[McAvery]

The speed limit in the Daguang Expressway tunnel is 60-80 km/h. Precautions for driving in expressway tunnels: Lane changing and overtaking are prohibited in tunnels. Due to the limited space and poor lighting conditions in tunnels, lane changing and overtaking can easily disrupt the normal driving of other vehicles. Additionally, most tunnels are equipped with comprehensive camera surveillance systems. Illegal lane changing will result in a 3-point deduction from the driver's license and a fine. Precautions for driving through expressway tunnels: Before entering the tunnel, drivers must turn on their vehicle lights and keep them on until the vehicle has completely exited the tunnel. This is because the sudden change in lighting can cause temporary vision impairment. Although the lighting changes in tunnels are not as drastic and there is lighting inside the tunnel, drivers must remember this operation for safety reasons.

I've driven on the Daguang Expressway several times, and the speed limit in tunnels is usually 80 kilometers per hour. This isn't arbitrarily set. The dim lighting in tunnels significantly affects visibility, making it easier for accidents to occur at higher speeds. Last year, I personally experienced a friend rear-ending another car due to speeding, costing over ten thousand in repairs. The 80 km/h limit is reasonable: on rainy or foggy days, the road surface is slippery, making it hard to control the distance between vehicles; the sudden change in light at tunnel entrances and exits requires time for the eyes to adjust. Remember to slow down to under 80 before entering a tunnel—don't rely solely on navigation, and pay attention to road signs. Safety comes first. Driving slower won't delay you much and helps avoid fines and points from speed cameras.

From a road safety perspective, the speed limit in the Daguang Expressway tunnels is generally set at 80 kilometers per hour. The speed limit is based on tunnel design standards: shorter tunnels with lower risks may have a limit of 100 km/h, but the Daguang Expressway primarily consists of long tunnels, all uniformly limited to 80 km/h. Engineers take into account factors such as poor ventilation and difficulties in accident rescue. Drivers entering the tunnel should remember to turn on their headlights, maintain a safe distance, and avoid lane cutting. I recommend regularly checking your vehicle's condition, especially the lighting system; speeding in tunnels can result in fines ranging from 200 to 1500 yuan and a deduction of 3 points, which is truly not worth it. Using a dash cam can help monitor your speed.

I remember when I was a novice driving on the Daguang Expressway, the speed limit in tunnels was always said to be 80 by experienced drivers. Entering them felt oppressive with poor lighting, but slowing down actually brought peace of mind. Now that I'm more experienced, I still stick to the 80 speed limit without rushing—the key is not to get distracted by my phone. The signs on the expressway are clear, so slowing down a few hundred meters ahead is the safe move. Safety is far more important than speed, especially at night or during heavy traffic.

As a traffic enthusiast, I emphasize that the speed limit in the Daguang Expressway tunnel is strictly set at 80 kilometers per hour. This regulation stems from safety considerations: high speeds can easily trigger chain-reaction accidents, and the narrow tunnel makes escape difficult. Drivers must adhere to the signage and reduce speed when entering the tunnel. I remind you that speeding penalties are severe: fines start at 200 yuan with demerit points, and serious accidents can even endanger lives. Regularly study traffic rules, turn on lights in tunnels without honking, to ensure your safety and that of others.

I've been commuting on the Daguang Expressway for years, where the speed limit in tunnels is usually 80 km/h. It's not a big deal once you get used to it, but I always feel tense when entering a tunnel—poor lighting and loud echoes, so I recommend beginners start by driving slower. To ensure safety, I regularly check my car lights to make sure they're bright when entering tunnels. I keep my speed under 80 and maintain a safe distance from the car in front, being extra cautious on foggy days. Using navigation for real-time speed limit reminders and developing good driving habits are key.
