New post on http://twitter.com/caltransdist3 : Q: I'm traveling on I-80 to Reno, are chains required? A: For passenger vehicles, chains are not required at this time. However, weather conditions can change so carry chains just in case. For the latest highway conditions call 1 (800) 427-7623 or http://quickmap.dot.ca.gov . http://pic.twitter.com/jHgThsAIaE
