Road signs in Denmark are regulated by the Road Traffic Act (). The Danish Minister of Transport is responsible for the design and definitions of road signs, and issues executive orders on the subject. The latest executive orders were issued on .
Denmark signed the Vienna Convention on Road Signs and Signals on and ratified it on . Denmark has ratified the European Agreement supplementing the Convention on road traffic as well.
Road signs are divided into two main categories, which are traffic signs and direction / tourist information signs.
Outside built-up areas, warning signs, except A18, A35, A74, A75 and A92, are usually placed from 150m to 250m before the danger. If the warning signs are placed beyond this distance, the distance is shown on a subpanel. Inside built-up areas, warning signs can be placed at a shorter distance from the danger, without the distance being shown on a subpanel.
On motorways, direction signs have blue background when they lead to the ordinary road network, via an exit from the motorway, Directions have green background when they lead to the destination via the motorway(s).
A broken line around the number means the road connects to the route with that number.
New service signs are designed when they are required, for example by request from a business. Proposed additions include "electrician" and "real estate agent".
These signs can be placed below traffic and direction signs. Subpanels with blue background are combined with signs that have blue background, and subpanels with white background with signs that have white background. The signs can for instance be used below parking restriction signs to indicate which time of day, what day(s) of the week or the duration of parking for which the restriction applies,
