Lane Signs - Page 7

A lane sign is needed anywhere a road undergoes a change that affects how drivers use a lane, such as construction, a merge point, a restricted-use lane, or a lane closure, since bright orange and yellow lane signs attract attention and give drivers advance warning even on a crowded or busy road.

Yes, many lane signs are MUTCD compliant, and the collection includes both officially compliant designs, such as diamond-shaped warning signs, and non-MUTCD options suited for private roads.

Lane signs primarily use two color and shape combinations: yellow diamond-shaped signs, such as Right Lane Ends or One Lane Road Ahead, warn drivers of a change in road conditions ahead, while white rectangular signs, such as Stay in Lane or Right Lane Must Turn Right, indicate a legal traffic requirement drivers must follow.

A lane sign's shape and color reveal whether it's mandatory or optional: white rectangular regulatory signs, such as Stay in Lane or Right Lane Must Turn Right, indicate a legal requirement drivers must follow, while yellow diamond-shaped warning signs, such as Right Lane Ends or One Lane Road Ahead, alert drivers to a condition ahead without legally mandating a specific action.

Lane signs are made primarily of aluminum, available in standard, heavy-duty, and reflective grades, with a limited selection also available in plastic and vinyl reflective materials. Reflective lane signs come in three grades of visibility: Engineer Grade, the most common standard option, offering basic reflectivity in dark conditions; High Intensity Grade, offering up to three times the reflectance of Engineer Grade with especially strong performance when viewed at an angle; and Diamond Grade, offering the highest reflectivity available, with strong daytime visibility and superior nighttime performance, making it well suited for busy roads with heavy visual distraction.
