Missing license plate on rental car
I'm currently renting a car from Hertz in LA, and I noticed arriving back at my hotel that the rear license plate has fallen off somewhere on today's road trip to the Hoover Dam (it was on there yesterday).
The car is registered in Florida which has no requirement for a front plate, so I'm now stuck with a car in California with no plates whatsoever!
I need to move between hotels tomorrow but I'm currently scratching my head as to the next steps I should take given it's not an emergency (and I didn't pay for the additional roadside assistance). I've tried contacting Hertz but they're going through to voicemail (currently 9PM local time).
Any suggestions for what I should do tomorrow? I'll keep trying to contact Hertz but the other options would be to try finding the nearest DMV or taking the car back at risk of driving without any plates...
