What are the types of signs on highways?
2 Answers
Highway signs include road type signs, common lane and speed limit information signs, and special category signs such as tunnel warning signs. Road type signs: Highways, which are the highest grade of roads, have completely different speed limits and road conditions compared to urban roads. They are fully enclosed spaces. In signage, they are generally marked with the letter 'G' at the beginning, similar to national highways, such as G3. Common lane and speed limit information signs: Speed limit signs, such as 100km/h or 120km/h. Service area information signs are indicated by the uppercase letter 'P' on highway service area signs, accompanied by symbols of a fuel pump, fork and knife, and a wrench. Special category signs - tunnel warning signs: Some highways pass through tunnels. When approaching a tunnel, signs will display the tunnel's name and distance.
As a seasoned highway driver, I often see various signs that are very helpful for driving. Entrance and exit signs tell you where to get on and off the highway to avoid missing them; speed limit signs remind you not to drive too fast, usually marked with 110 or 120; service area signs indicate gas stations and rest stops, useful for refueling and taking breaks on long drives; directional signs show road names and distances, such as how many kilometers to Shanghai; safety signs include construction warnings and no-passing zones, especially important to heed at night; emergency signs like runaway truck ramps and emergency phones are there in case of accidents. There are also information boards displaying weather or traffic conditions. Having driven for over a decade, these signs are like a compass, constantly reminding me to drive safely—never ignore them.
