Central American Manual on Uniform Traffic Control Devices
The Central American Manual on Uniform Traffic Control Devices (Spanish: Manual Centroamericano de Dispositivos Uniformes para el Control de Tránsito) is a standard for road signs, signals, and markings in Central America based on the American Manual on Uniform Traffic Control Devices (MUTCD). It is published by the Secretariat for Central American Economic Integration (SIECA) for the countries of the Central American Integration System (SICA), particularly Costa Rica, Guatemala, Honduras, El Salvador, and Nicaragua. The latest edition was published in 2014 (as of 2025).
Usage in OpenStreetMap
A traffic sign is mapped as a 
node tagged traffic_sign=SICA:Z1-2, where Z1-2 is the sign's alphanumeric designation. Unlike the Vienna Convention on Road Signs and Signals, the Central American Manual on Uniform Traffic Control Devices specifies a coded system of signs that is used directly by several SICA member states. However, some SICA member states such as Panama do maintain their own sign codes; consult the country-specific page for tagging details.
Sign designations
Each standard sign or plaque in the Central American MUTCD is assigned an alphanumeric designation and organized by series. A sign designation follows this format:
| Category | Series | Sign | Variant | |
|---|---|---|---|---|
| R | 11 | - | 1 | b |
| Regulatory | Safety Zones and Pedestrian Bridges | No Pedestrian Crossing | Symbol Sign |
Signs by series
The following pages contain a correspondence between Central American MUTCD signs and their most likely tagging in OpenStreetMap:
- Series R – Regulation
- Series P – Prevention
- Series II – Identifying Information
- Series ID – Destination Information
- Series IS – Service and Tourism Information
- Series IR – Recreational Area and National Park Information
- Series IE – Civil Defense and Emergency Information
- Series IG – General Information
- Series PP – Prevention in Temporary Traffic Control Zones
- Series IP – Information in Temporary Traffic Control Zones
- Series E – School Zones
- Series B – Bicycles
Unless otherwise specified, apply the suggested tags to whatever the sign refers to, which is typically not at the precise location of the sign itself. Optionally, you can also map the sign itself as a traffic_sign=* node.
