Download the main manuals for your signage projects for free
In the development of road signage projects on state highways, it is very common to work with the DERs (Departments of Highways), the bodies responsible for the management, operation, and oversight of the state highway network. These projects require special attention to specific technical standards, since any inconsistency can lead to rework, delays, or challenges during the approval and execution phases.

To support the designer in this scenario, it is essential to consult the signage manuals and technical studies adopted by each DER (Department of Roads and Highways), which complement the national guidelines and establish their own criteria for the application of road signage.
With this in mind, SEABRA has compiled in this content a collection of the main road signage manuals and manuals for preparing studies used by the DERs (Department of Roads and Highways). Below each volume, you will find a link for free download, allowing for practical and recurring consultation during the development of your projects.
In practice, the correct application of these standards can also be facilitated by the use of specialized tools. sinC It allows the development of road signage projects aligned with the guidelines adopted by the DERs (Department of Roads and Highways), assisting in the implementation of vertical and horizontal signage, safety devices, works, and quantities in a manner consistent with current technical manuals.
