How do I indicate to the tool that my vehicle cannot use specific roads?

If you're using one of our pre-defined profiles such as avoidsteep3wheeler, we expect you to update the OpenStreetMaps data to reflect the reality of the road network. For example, you can add relevant tags to the roads if the surface makes driving difficult (surface=sand), a street is too steep (incline=steep), or a barrier is present (access=private on a segment of the road).
