Merge Signs

Many merge signs, such as the Right Lane Ends, Left Lane Merge, and Lane Ends Merge Left/Right signs, are MUTCD compliant, built to official federal specifications for shape, color, and legend, while the collection also includes non-MUTCD merge signs suited for private roads and parking lots where MUTCD compliance isn't required.

A merge sign should be installed before the point where the lane actually narrows or ends, giving drivers enough distance to safely adjust speed and merge before reaching that point. MUTCD guidance recommends placing merge signs farther back on higher-speed roads than on slower ones, since merging requires drivers extra time to make a more complex driving decision. A Right Lane Ends or Left Lane Ends sign can also be installed even earlier than the main Merge sign to give drivers additional advance warning.

Merge signs are available in Engineer Grade, offering basic reflectivity and at least 7 years of outdoor life, suitable for lower-traffic private roads; High Intensity Grade, offering up to three times the reflectance of Engineer Grade, suitable for busier roads with moderate traffic speeds; and Diamond Grade, offering ten times the reflectivity and at least 12 years of outdoor life, recommended for high-speed roads or merge points with heavy traffic and limited visibility.

Merge signs are made primarily of aluminum, available in standard, reflective, and heavy-duty grades, with a smaller selection also available in plastic, reflective polyester, and reflective vinyl.

Merge signs are available for a range of specific scenarios, including Left Lane Ends, Right Lane Ends, Lane Ends Merge Left, Lane Ends Merge Right, Left Lane Merge, Right Lane Merge, Left Added Lane, Right Added Lane, Entering Roadway Merge Left, Merging Traffic, and Intersection Merging Symbol signs
