QGIS Attribution and Geometry Query Question

I am trying to use select by expression to query lines that contain certain attributes and that there geomerty touch. In other words are connected or neighbor each other.

I tried a query such as this. My attribution might not make sense but i just need the syntax correct.

"isDiscouraged" = 't' AND touches("roadclass" = 'ramp')

or

"Links that have this attribute" AND Touch "links that have this attribute"

So i want to find links that contain the attribute isdiscouraged = t that are connected to links with this other attribute roadclass = ramp. Is this possible. My above query is invalid but lays out what im looking for. Any ideas how to tweek it to make it work.

I know its kind of a more spatial query combined with attribute query but cant get it to work!

Thanks
