Here is relevant information about speed limits: Special road sections have speed limits: Tunnel entrances, inside tunnels, accident-prone sections, bridges, roads under maintenance, temporary speed limit zones, long downhill sections, etc., all have speed limit signs. Drivers need to pay attention to the speed limit signs on the roadside and drive cautiously. Penalties for speeding: Speeding within 10% results in a warning. Speeding between 10%-20% incurs 3 penalty points, speeding between 20%-50% incurs 6 penalty points, and speeding over 50% incurs 12 penalty points, along with varying amounts of fines.
