Highway tunnel speed limits range between 60km/h to 80km/h, while urban road tunnel speed limits are between 40km/h to 60km/h. Highway tunnel speed limits range between 60km/h to 80km/h. Lane changing and overtaking are prohibited in tunnels due to limited space and poor lighting conditions, which can easily disrupt normal traffic flow. Additionally, most tunnels are now equipped with comprehensive camera surveillance systems, and illegal lane changes may result in a 3-point penalty and a fine. Urban road tunnel speed limits are between 40km/h to 60km/h. The maximum speed for vehicles passing through tunnels is determined by the management unit based on actual road conditions. When approaching a tunnel, speed limit signs will be prominently displayed at the entrance, and there will also be speed limit reminders inside the tunnel. Traffic police departments enforce management according to the speed limits set by the competent authorities. Considering that the design speed and actual operating speed may sometimes be inconsistent, drivers may appropriately increase their speed below 60km/h to improve traffic efficiency, provided that safety is not compromised. However, the speed must not exceed 50% of the posted limit, and violations will be penalized according to the law. Before entering a tunnel, drivers must adjust their speed according to the speed limit signs on both sides of the road. Headlights should be turned on before entering the tunnel and turned off after completely exiting. Due to the limited space and poor lighting conditions in tunnels, illegal lane changes are prohibited. Modern tunnels are equipped with advanced camera systems that can clearly capture and upload evidence of any violations.

What does 'trip' on the dashboard mean?

The 'trip' on the car dashboard represents the trip mileage, which can be used to record the distance traveled for each trip. Here is a related introduction to the car odometer: 1. The tachometer is usually located inside the instrument panel, placed symmetrically with the speedometer. The tachometer operates based on magnetic principles, receiving pulse signals generated when the primary current in the ignition coil is interrupted. The car odometer includes two LCD digital display windows connected to the same signal source, which respectively accumulate the current trip mileage and the total mileage. The current trip mileage typically has four digits for short-term counting and can be reset. The total mileage has six digits and cannot be reset. The accumulated mileage numbers in an electronic odometer are stored in non-volatile memory, preserving the data even when there is no power. 2. The car odometer is usually located directly in front of the driver's position. A typical mechanical odometer is connected to a flexible shaft containing a steel cable. The other end of the flexible shaft is connected to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, which in turn drives a magnet inside the odometer's housing to rotate. The housing is connected to the pointer and, through a hairspring, positions the pointer at zero. The speed of the magnet's rotation causes changes in the size of the magnetic lines of force, disrupting the balance and thereby moving the pointer.
