Just a word of caution for those who drive around downtown Los Angeles area and drive on the Express Lane toll roads (10 freeway & 110 freeway).
CHP is out in full force this year, pulling people over with valid HOV stickers on their cars and ticketing people who do not set their Fastrak transponders to the correct number of people in the car. Meaning, the HOV decals do not exempt you from setting your transponder to 3+ (like we've been able to years prior) while driving solo on the Express Lanes in Los Angeles, as stated on their website as of May 2019. You can still drive solo in non-toll roads in CA with HOV stickers.
I was pulled over a couple of weeks ago (with a passenger in my front seat, in a row of cars while driving home) and still ticketed by the CHP officer who had nothing better to do than sit in front of the transponder sensor and pull people over who had a 3+ setting on their car. The cost... a $243 ticket. Had I put my transponder to the 2 setting, the trip would've cost me like $4 at that time from where I entered and exited the Express Lanes, so I intend to contest this ticket in court to at least reduce the fee.
