Guanglong Expressway has a speed limit of 100 kilometers per hour. Additional information: Expressway speed limits refer to the driving speed on express lanes. Expressways should clearly mark the driving speed for each lane, with the maximum speed not exceeding 120 kilometers per hour and the minimum speed not falling below 60 kilometers per hour. On expressways, the maximum speed for small passenger vehicles should not exceed 120 kilometers per hour, while other motor vehicles should not exceed 100 kilometers per hour, and motorcycles should not exceed 80 kilometers per hour. Relevant regulations: According to the "Road Traffic Safety Law Implementation Regulations," when encountering low visibility weather conditions such as fog, rain, snow, dust, or hail on expressways with visibility less than 200 meters, drivers should turn on fog lights, low beams, marker lights, and front and rear position lights, and the speed should not exceed 60 kilometers per hour, maintaining a distance of more than 100 meters from the vehicle ahead in the same lane. When visibility is less than 100 meters, drivers should turn on fog lights, low beams, marker lights, front and rear position lights, and hazard warning flashers, with the speed not exceeding 40 kilometers per hour and maintaining a distance of more than 50 meters from the vehicle ahead in the same lane. When visibility is less than 50 meters, drivers should turn on fog lights, low beams, marker lights, front and rear position lights, and hazard warning flashers, with the speed not exceeding 20 kilometers per hour, and exit the expressway at the nearest exit as soon as possible.

I've driven on the Guanglong Expressway in Guangdong a few times, where the speed limit is usually 120 kilometers per hour, but don't assume it's the same for the entire road. Once, when I went through the tunnel section, the road sign clearly stated a speed limit of 100 kilometers per hour. I almost exceeded the limit because I wasn't paying enough attention. Only after getting fined did I realize that the fine was even more expensive than the fuel cost. Safety first—driving too fast in rainy or foggy conditions can easily lead to skidding, especially in bridge areas where the speed limit sometimes drops below 100. I recommend using a GPS navigation app for real-time reminders and ensuring your car is well-maintained with brakes and tires checked. Remember, keeping your average fuel consumption within 120 can save you some money. In short, pay attention to road changes, don't rush, and drive steadily—it's the most practical way.

I've been driving for half my life, and the speed limit on the Guanglong Expressway is mostly 120 km/h, but honestly, it often drops to 100 km/h in mountainous areas or sharp bends. Speeding is no small matter—tickets can cost hundreds of yuan, plus points deducted, which is really not worth it. The condition of your car is also crucial; older cars tend to shake at high speeds, so it's best to set cruise control. From my experience, maintaining a safe distance and staying focused are more important than speed. In rain or fog, the speed limit automatically decreases—don't risk accelerating. Make it a habit to check road signs and ensure your GPS is updated before starting your journey. This way, you'll drive with peace of mind and ease.

I always stick to the 120 km/h speed limit when driving on the Guanglong Expressway, but the speed limit often drops to 100 km/h at entrances, exits, and tunnels. Staying within the speed limit not only avoids tickets but also ensures safety, especially in rainy weather when extra caution and maintaining distance are crucial. Navigation apps are a big help, alerting me to changes in speed limits. A simple piece of advice: drive steadily and safely.
