What is the maximum speed limit in an underground parking garage?

For safety reasons, the speed limit is set at 5 km/h or below. Maximum vehicle speed: Refers to the highest attainable speed a vehicle can achieve on a level, good-quality road surface (concrete or asphalt). It represents the speed at which driving resistance and traction force balance under windless conditions on flat terrain, serving as one of three key performance indicators for vehicle dynamics. Multiple factors affect maximum speed, including engine power, maximum torque, torque peak RPM, transmission gear ratios, and driving resistance. Safe driving speed: Under circular motion conditions, the safe speed is approximately 60 km/h. Actual safe speeds should be adjusted according to weather, road conditions, and other situational factors.
I've driven through quite a few underground parking garages, where the maximum speed is usually controlled between 5 to 10 kilometers per hour. Once I drove a bit too fast and nearly scraped a pillar at a turn, leaving a scratch on the car body. Since then, I always slow down to the minimum speed when entering garages because the space is too narrow, with blind spots, pedestrians, and small animals suddenly appearing. Exceeding 10 km/h makes it difficult to control the steering wheel, and with the increased braking distance, the risks are significant. Especially on rainy days when the ground is slippery, maintaining low speed can prevent skidding or collision accidents. I recommend everyone to slow down before entering the garage, stay alert, prioritize safety, and avoid unnecessary trouble and repair costs.
As a safety-conscious car owner, I strictly adhere to driving no faster than 5 kilometers per hour in underground garages. The confined space, crowded with people and vehicles, along with obstructing pillars, makes accidents more likely at slightly higher speeds. According to common standards, the maximum speed is set around 5 km/h primarily to ensure pedestrian safety, such as parents with children or elderly individuals coming and going. I constantly remind myself to drive slowly, paying attention to rearview mirrors and warning signs, ensuring a short braking distance to promptly handle sudden situations. Driving in a garage should be as gentle as stepping on an ant—it's not just a rule but a responsible attitude towards life for both myself and others.
