## Coverage

This page shows full-road conditions reported by MountainSwitch's listed I-80 sources, including District 3 feed rows outside the modeled Truckee and Lake Tahoe approaches.

Those route-wide reports don't expand either verdict. Truckee covers the known I-80 access paths from Colfax and the California–Nevada state line to the Truckee junction; Lake Tahoe's I-80 gate covers Colfax through Donner Summit to that junction. Neither verdict covers Nevada-side I-80 beyond the state line. District 3 Washoe County rows may remain visible route-wide as source truth, but they do not contribute to either verdict.

MountainSwitch does not determine whether a route should be driven. Verify with Caltrans before traveling.
