What is the maximum speed limit in tunnels?
1 Answers
Tunnel speed is limited to a maximum of 40 kilometers per hour. During severe weather conditions and in special sections such as bridges and tunnels, the speed limit is subject to the on-site speed limit signs. Speed calculation formula: The calculation method for speed is V=S/t, which represents the distance traveled per unit of time. The speedometer uses data monitored by sensors, calculating the actual speed of the vehicle based on the number of wheel rotations, diameter, and time. Precautions for driving into tunnels: Reduce speed and turn on lights before entering the tunnel, avoid using high beams, strictly adhere to speed limits, do not honk inside the tunnel, do not exit the vehicle for repairs, maintain a safe distance, do not change lanes, accelerate promptly after exiting the tunnel, place warning signs quickly if the vehicle breaks down in the tunnel, and evacuate all passengers.
