What is the width of road diversion markings?
3 Answers
Road diversion line widths are as follows: Lane demarcation lines: The width of crossable same-direction lane demarcation lines is generally 10cm or 15cm. For special applications such as rural roads with very low traffic volume or exclusive dedicated roads, the line width may be reduced to 8cm. Design speed: For roads with design speeds ≥60km/h, the dash length and spacing of crossable same-direction lane demarcation lines are 600cm and 900cm respectively. For roads with design speeds <60km/h, Same-direction lanes: The dash length and spacing of crossable same-direction lane demarcation lines are 200cm and 400cm respectively.
I drive quite frequently, and those road diversion markings—the lines that guide drivers to turn or separate lanes—are generally about 15 centimeters wide, roughly the width of a pencil. This standard is set so that drivers can see them clearly from a distance, avoiding wrong turns or accidents. I’ve seen on highways where the lines are too thin, especially in rain or fog, and the reflection of light can easily blur them, making me almost swerve into the next lane. Remember, lane markings aren’t arbitrarily determined; they’re calculated based on speed and sight distance. Where speeds are higher, the lines are thicker, while in urban areas with slower speeds, they might be thinner, but most of the time, they stay between 10 to 15 centimeters. If drivers pay attention to these details, their driving will be safer.
Speaking of the width of road diversion markings, as a long-haul driver, I must emphasize its safety significance. The width is typically between 10 to 15 centimeters, with the standard being 15 centimeters, which is particularly crucial during night driving or in harsh weather conditions. Once, while driving in heavy rain, the worn-out lines had narrowed, and under scattered light, I nearly misjudged the direction, almost causing a rear-end collision. Traffic experts explain that this width design ensures visibility from 500 meters away, reducing distracted driving. I advise drivers to regularly check road conditions and report any worn-out lines for repair immediately—don't wait for an accident to regret it. The fixed width is there to ensure we all get home safely.
