(KTXL) — The season’s first significant storm left the Sierra Nevada covered in snow from Tuesday through Wednesday.

On Tuesday night when the storm began, chain controls were needed on all commercial vehicles on Interstate 80 and U.S. Route 50.

Despite the storm starting to end Wednesday, chain controls are still needed on I-80 over Donner Summit, according to California Highway Patrol Truckee. Click here for the latest information on road conditions and chain control updates.
