Frequently Asked Questions
Do I need chains with AWD or 4WD on US-50?
During R1 controls, AWD/4WD with snow tires can pass without chains. During R2, AWD/4WD with snow tires on all four wheels may proceed. During R3, chains are required on ALL vehicles — AWD and 4WD included. US-50 over Echo Summit has steep grades, so proper traction is critical.
How many chains do I need for US-50?
You need 2 chains minimum, installed on your drive wheels. Front-wheel-drive vehicles chain the front tires; rear-wheel-drive chain the rear. The steep grades on Echo Summit make proper chain installation especially important — loose chains can cause damage or loss of control.
Can I use AutoSock or snow socks instead of chains on US-50?
AutoSock is Caltrans-approved for R1 and R2 chain controls on US-50. During R3, only traditional metal chains are accepted. Given Echo Summit's steep grades, many drivers prefer chains over fabric alternatives for the added grip.
