Don't go through between 6am and 10am or 2pm and 6pm. If you do it will be a long wait in traffic. I left Torrance at 4:30pm and got to Barstow at 11pm on a Friday night (130 miles).
Show your bills at the bug station when you enter the state.
Don't stop at the TA's on I-10 in Ontario.
Trucks only in right 2 lanes in California........3rd lane will get you a big ticket.
Keep your space.....Traffic comes to a stop when you least expect it.
Don't miss the truck route when you get on the 5 north. The scale on 5 pops up quick too.
If you need to stop and wait, stop east of the city in Coachilla or around there where the truck stops are.
If you are coming in on the 10 you need to jump on the 15 to get to the 210........The 210 ends at the 5
