In several regions, especially on state highways and rural roads, there is an abrupt transition in pavement—for example, the end of the asphalted section and the beginning of a dirt or basalt-stone road. These sudden surface changes can catch drivers by surprise, particularly during low-visibility hours, adverse weather conditions, or on higher-speed roads.

Technical and Road Safety Justification:
Changes in pavement type can pose significant risks to drivers, such as:
Rear-end collisions, when the vehicle ahead suddenly slows upon noticing the change in pavement;
Loss of control and roadway departures, due to loose gravel, irregularities, or reduced traction on dirt or basalt surfaces;

Increased braking distance, especially when transitioning from asphalt to a more unstable surface.
A similar situation is already recognized by road authorities, and several highways physically signpost “End of Pavement.” The alert would follow the same usability logic and importance as the current “Sharp Curve,” “Complex Intersection,” and other warnings already implemented in the app.

Implementation Proposal:
Create a new type of permanent alert that allows editors to map points where the following occurs:
End of asphalt pavement, or
Transition to gravel/basalt stones/compact dirt.

This alert would be displayed to drivers with adequate advance notice, allowing for planned speed reduction and improved operational safety, aligning with good practices in road signage and accident prevention.
