Option #1: Buy and Carry a pair chains that fit your vehicle(regardless if your vehicle is 2X, 4 X 4 or AWD) so when and/or if you are ever asked by the folks at any Chain Control Stop to produce them and then do, subsequently allowing you to continue on your marry way.
OROption #2: Don't carry any chains regardless vehicle type then when and if you are asked to produce them at any Chain Control Stop, you can't, and then basically tell the CCS folks to kiss your ass, subsequently be told to turn around or remain in line for God knows how long (up to 48 hours in some cases here locally at the bottom of the Bishop Grade or up at Walker just north of Walker Pass).
Bishop/Minden area Motels and businesses love it when Caltrans/CHP impose and vigilantly monitor mandatory R2 and then R3 restrictions and the proverbial wise asses argue with the CHP. They did it over 12 times last season alone. On three occasions for over 48 hours due to high drift conditions as a results of blowing snow.
R2: Chains or traction devices are required on all vehicles except four wheel/ all wheel drive vehicles with snow-tread tires on all four wheels.(
NOTE: Four wheel/all wheel drive vehicles must carry traction devices in chain control areas.)R3: Chains or traction devices are required on all vehicles, no exceptions.
http://www.dot.ca.gov/hq/roadinfo/wntrdriv.htmJust thought I would add to obvious Option available. FWIW, as DSKOON posted, I too have, carry them all the time in both of my 4X4 Trucks and have had to actually put them on several times the past three seasons between Bishop and Lee Vining. Now back to my hiding....
