etterskilt

Etterskilt is a term used in Norwegian signage to refer to a supplementary plate that accompanies a primary road sign to convey additional or conditional information. In practice, an etterskilt clarifies the scope of a regulation, adds time limits, days of operation, or exemptions, and may indicate that the rule applies only after a certain point or under specified conditions.

Placement typically involves a small rectangular plate mounted directly below or after the main sign. The text is short and uses a standard font to ensure legibility. An etterskilt can specify time windows (for example, weekdays 07:00–19:00), vehicle classes (such as restrictions for certain weights or types), or other limitations. Its use allows authorities to apply nuanced rules without creating a multitude of separate main signs for every variation.

In official Norwegian road signage, the term most commonly used for these elements is tilleggsplate, meaning supplementary plate. Etterskilt is thus often considered a descriptive or colloquial term that describes the function of these plates rather than a formal designation in all regulatory texts. The regulatory framework for road signs is administered by national authorities and aligned with broader European standards for traffic signage.

Beyond traffic contexts, the term etterskilt is rarely used in formal documentation and is more likely encountered in everyday language or regional references.
