Remarks
A speed limit is defined as a single-link constraint that applies to the specified link and that is valid for this Route's VehicleSpec. If no such speed limit applies, then the link's posted speed limit is returned. If the data for the link does not contain a posted speed limit then -1 is returned.

overweight.GrossWeight_kg = 4000;

using (Route rt = new Route()) {
       rt.VehicleSpec = overweight;
       double speedLim = rt.GetVehicleSpeedLimit(new LatLon(41.472460, -81.857430),
