How to distinguish between highway entrance and exit markings?
2 Answers
Highway entrance and exit markings are distinguished by their fundamental differences. Here are the relevant introductions: 1. Highway entrance: A highway entrance belongs to the entrance of a high-grade road, referred to as a highway entrance. According to the "Technical Standards for Highway Engineering" issued by the Ministry of Transport of China, a highway is defined as "a road that can accommodate an average annual daily traffic volume of more than 25,000 passenger cars, is exclusively for high-speed divided-lane driving, and has fully controlled access." 2. Exit markings: Exit markings use different colored lines to constantly remind road users of highway exits. Traffic signs are generally placed on both sides of the road or at intersections, while markings are directly painted on the road surface.
As a seasoned driver with over 20 years of experience, I distinguish between highway entrance and exit markings based on practical knowledge. Entrance markings typically follow immediately after the ramp, consisting of white dashed lines or arrows pointing toward the main lanes, designed to guide safe acceleration and merging—I always pay attention to how these lines direct traffic flow into the main lanes. Sometimes, they include reflective markers for better visibility. Exit markings, on the other hand, often feature yellow-edged lines or forked arrow patterns, signaling an upcoming off-ramp, accompanied by deceleration lane markings as a reminder to brake. In practice, entrance sections demand focused attention to merge smoothly and avoid accidents, while exit markings appear well in advance to prevent missed turns. Although smart navigation systems are helpful, these markings remain reliable companions; regular observation enhances safety.
