Sierra Chain Controls Active: Speed Limits Drop on I-80 and Highway 50

Key Details Chain controls remain in effect across Northern California's Sierra Nevada region through Thursday as rain and snow continue to impact the area. The wet weather began Tuesday, April 21st, and fell as snow in the mountains Wednesday morning. Conditions are expected to improve by afternoon, though additional precipitation may return Thursday. Speed Restrictions Drivers should be aware of significant speed reductions now in effect. Interstate 80 speeds have been cut to 30 mph, while Highway 50 is limited to 25 mph. These restrictions apply across all affected mountain corridors. Specific Chain Requirements Eastbound I-80 requires chains from Colfax to Truckee. Westbound I-80 needs chains from the Donner Lake Interchange to 2.1 miles past Baxter. Highway 88 has chain requirements from Dew Drop to 6.5 miles east of Peddler Hill in Amador County. Highway 89 requires chains starting 2.7 miles south of the Highway 50 junction through the El Dorado-Alpine County line. Chain controls have been active since Tuesday. Why It Matters These conditions demand extra caution and preparation. Ensure your rig is equipped with proper chains and allow additional travel time through the Sierra passes. Monitor weather updates for any changes to restrictions.
