MnDOT Pavement Marking Standards and Their Impact on Traffic Management
Key Updates in Line Width, لون, and Patterns
ال Minnesota Department of Transportation made big changes to pavement marking standards. These changes focus on line width, لون, والأنماط. The goal is to help guide and protect everyone on the road. Center and lane lines are now wider at 6 بوصة. Before, they were only 4 بوصة واسعة. Lane lines are longer now, القياس 12.5 feet instead of 10 قدم. The space between lane lines is a little shorter at 37.5 قدم. Edge lines are still 6 بوصة واسعة. Concrete roads now use lag contrast patterns. These patterns have white and black markings to make them easier to see.
| وجه | Current Standard | New Standard (Effective 2026) |
|---|---|---|
| Center Line Width | 4 بوصة | 6 بوصة |
| Lane Line Width | 4 بوصة | 6 بوصة |
| Lane Line Length | 10 قدم | 12.5 قدم |
| Lane Line Spacing | 40 قدم | 37.5 قدم |
| Edge Line Width | 6 بوصة | 6 بوصة |
| Contrast Markings | لا أحد | Lag contrast pattern (أبيض/أسود) on concrete roads |
Studies show that wider lanes and double solid lines help drivers stay safe. Drivers like wider white markings and longer lane lines. These markings help drivers see lanes sooner and make fewer lane changes. The new changes follow the best ways to mark roads and manage traffic.
New Retroreflectivity Requirements for Improved Night Visibility
MnDOT now has higher retroreflectivity rules for pavement markings. These rules make sure markings are easy to see at night and in bad weather. On local and minor collector roads, white markings must be at least 80 mcd/m²/lux. Major collectors and highways need white markings at 100 mcd/m²/lux. Yellow markings also have higher minimums.
| Roadway Classification | New Minimum Retroreflectivity (mcd/m²/lux) | Previous Standards |
|---|---|---|
| Local and Minor Collector (أبيض) | 80 | Lower than 80 |
| Major Collector and Arterial (أبيض) | 100 | Lower than 100 |
| Highways and Freeways (أبيض) | 100 | Lower than 100 |
| Local and Minor Collector (أصفر) | 65 | Lower than 65 |
| Major Collector and Arterial (أصفر) | 80 | Lower than 80 |
Carlson and Hawkins did a study. They found that brighter freeway guide signs helped people read them from farther away. The signs could be seen about 53 feet farther. This means better retroreflectivity helps people see at night. But it is not clear if it lowers crash numbers.
Transportation agencies say higher إعادة الانفعال helps with safety and upkeep. ال FHWA Low-Cost Safety Improvements Pooled Fund Study keeps checking if these changes lower crashes at intersections without signals.
Updated Lane Marking Patterns for Enhanced Safety

Some other setups use even longer markings and shorter spaces. Drivers say these are easier to see and they like them more.
| Lane Marking Configuration | عرض (بوصة) | طول (قدم) | التباعد (قدم) | Preference Rating |
|---|---|---|---|---|
| Current MnDOT Standard | 4 | 10 | 40 | قليل |
| Recommended Configuration | 6 | 12.5 | 37.5 | عالي |
| Alternative Configurations | 6 | 20-30 | 15-25 | عالي |
