- Until around the 3rd Ave exit (Exit 416), drive in the leftmost lane. At the 3rd, start slowly switching lanes into the rightmost lane.
- The rightmost lane will start moving fastest because a lot of people will be switching to 92.
- 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.
- 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.
