What is the fishbone line traffic sign?
2 Answers
Highway fishbone line markings are called deceleration markings, mainly used to remind drivers to slow down. Location of fishbone line markings: Deceleration markings are usually set at bridge approaches and turns. Their main function is to create a sense of compression by visually narrowing the lane, prompting drivers to automatically slow down at curves, slopes, and other locations where deceleration is required. Meaning of highway fishbone lines: They indicate the need to slow down. Fishbone lines consist of alternating dashed and solid lines with varying spacing, creating a gradual narrowing-to-widening effect. This marking design aims to help drivers adapt to the deceleration process, serving as a reminder to begin slowing down.
The fishbone traffic markings actually refer to the fishbone-shaped deceleration lines painted on the road surface, which are not traditional signboards but ground markings. These parallel short lines arranged like fishbones are commonly seen at curves, near schools, or intersections. Designed to create an optical illusion that makes drivers perceive the road as narrower, prompting instinctive braking to slow down. I've found them particularly effective on urban streets for preventing speeding-related accidents. During poor weather conditions like heavy rain, these markings serve as an extra reminder to stay focused. After installation, the overall safety factor of the road section improves significantly. With over a decade of driving experience, I've observed that drivers who ignore these markings often get into accidents, while developing the habit of slowing down upon seeing them can prevent many troubles. When combined with other facilities like traffic lights, the effectiveness increases further. Traffic authorities find this measure cost-efficient with substantial returns.
