101S/92 Lane Choice Strategy

Do you commute down to the Valley from SF? Do you hate waiting in traffic? Here's a strategy that works when driving southbound on 101. At the 101 southbound/highway 92 intersection, lane choice in is crucial. Here's the strategy that minimizes time:

  1. Until around the 3rd Ave exit (Exit 416), drive in the leftmost lane. At the 3rd, start slowly switching lanes into the rightmost lane.
  2. The rightmost lane will start moving fastest because a lot of people will be switching to 92.
  3. Ride the rightmost lane until after the 92 exit. There will be a blue sign that says "Call Box". At the sign, start immediately switching to the leftmost or 2nd-to-leftmost lane. Note that in California, you are required to go at least 3 car lengths between lane changes.
  4. A lot of drivers will be entering from 92 onto 101S, causing the rightmost lanes to slow to a crawl. Meanwhile you will be cruising on the left-hand lanes.

This will easily shave 5 minutes off your morning commute.
