Query truck restrictions along a corridor

Returns all truck-related restrictions within a buffer around the straight-line path between two points. Uses PostGIS spatial intersection (ST_Buffer + ST_Intersects).

Searches across feature types: bridge_clearances, bridges, weight_restrictions, truck_restrictions, truck_routes, freight_corridors, truck_parking.

Results are ordered by distance from the corridor centerline. Each feature includes _distance_km in its properties.

Only restrictions in force now are returned: a feature whose active window has ended, or has not begun, is excluded. Seasonal limits (spring load restrictions) carry their window on start_time/end_time and are otherwise live year-round.

This endpoint does not filter by vehicle dimensions. height and weight are rejected with a 400 rather than accepted, because upstream feeds publish no normalized clearance or weight for roughly 97% of the structures along a corridor. Filtering on what little is normalized would drop everything we cannot judge, and a short list reads as "this route is clear" — the one wrong answer that matters.

This endpoint gives you the inventory along the corridor; deciding what conflicts with a specific vehicle is yours to do, or use POST /routing/route, which follows a real route and emits a warning per restriction it can actually evaluate against the truck profile.

Requires Pro+ plan with truck data access.
