No. Interstate is a proprietary sans-serif font by Font Bureau that requires a commercial license. You can use Overpass instead at no cost.
Yes, for most uses. Overpass has a similar look, but its character widths differ from Interstate, so text can reflow slightly. Check line breaks and spacing after switching.
