Free road sign blocks for AutoCAD (DWG): Vienna Convention warning, priority, prohibition, mandatory and information signs in colour

About the standard

The numbering (A warning, B priority, C prohibition, D mandatory, E special regulation, F facilities and services, G direction and information, H additional panels), the meanings and the shapes and colours follow the Vienna Convention on Road Signs and Signals in the version of its 2026 amendment. The Convention gives the shapes, colours and symbols and leaves some details to each country: lettering, border widths, pictogram variants and the signs that countries add themselves differ from country to country.

The library is not an official publication and is not certified. It is meant for plans, schedules and legends. For the signs that are made and put up on a road, use the sign drawings of your road authority, which govern in your country, and check the rules that apply to your project for sizes, sheeting classes and placement.

Frequently asked questions

Which signs are in the library?

244 signs in eight groups: 43 warning signs, 8 priority signs, 46 prohibition signs, 28 mandatory signs, 32 special regulation signs, 18 facility and service signs, 54 direction and information signs and 15 additional panels. The page above lists every sign with its Convention number.

Will the signs of my country look the same?

The signs of the Convention are the common basis for most countries in Europe, Asia, Africa and South America, but each country has its own national set, with local lettering, pictogram variants and extra signs. The signs in this library are the Convention signs. For a national set, use them as a base and replace the pictogram you need, or use the sign drawings of your road authority. North American signs follow a different system.

Can I use the symbols in commercial projects?

Yes. They are free to use and modify in your own projects, including commercial ones. They are provided as is, without warranty.

Why are the signs on colour layers, and will they plot in colour?

A road sign means something by its colour, so each sign is made of solid colour fills on its own layers. They plot in colour with a colour plot style. If you plot with a monochrome style the signs turn black and white; they stay recognisable, but you lose the colour meaning, so use a colour style for signing plans.

Can I change a symbol or add attributes?

Yes. Open the DWG, edit a block with BEDIT to change it or add attributes, and save. To update drawings that already contain the block, run ATTSYNC or replace the block. Make a backup first: attribute values can be lost if ATTSYNC is used carelessly.

Where do I find a ready-made set of these symbols for AutoCAD?

AutoCAD itself ships only a small set of sample blocks, so a full symbol set has to come from a library. Download the ZIP on this page and open the DWG: every symbol is a block. Insert one with INSERT (Blocks palette, Libraries tab, then pick the DWG) or drag it from DesignCenter (ADCENTER). You can also download a single symbol on its own.
