Are the diamond-shaped dashed lines on the road a warning to slow down ahead?
1 Answers
The diamond-shaped dashed lines on the road are technically called 'longitudinal deceleration markings for vehicle lanes'. These markings consist of a series of diamond-shaped dashed lines parallel to the lane dividing lines, serving as a warning to drivers that they should slow down in this lane. Below are specific details: 1. The specific shape of longitudinal deceleration markings for vehicle lanes: These markings are a series of diamond-shaped dashed lines parallel to the lane dividing lines. At the starting position of these markings, there is a 30-meter transition section where the diamond-shaped dashed lines gradually widen from 10 cm to 30 cm. This is one of the new markings added in the latest national standard for road traffic markings (GB5768.2-2009). 2. Precautions: When vehicles pass through sections with longitudinal deceleration markings for vehicle lanes, drivers will visually perceive the lane as gradually narrowing, which prompts them to increase their attention, actively take deceleration measures, and proceed slowly. This can effectively prevent drivers from applying emergency brakes just before the stop line.
