I parked my vehicle plus a trailor at two meters. I unfortunately didn't see the "tow-away 4-7pm" sign since it was at the bottom of the block (there was no sign at the top of the block). Nevertheless, I was there at 4:05, and I received a ticket at 4:03 for parking in the tow-away zone for twice the normal amount ($70 instead of $35) I'm assuming because of the attached trailor. Is there no grace period from when the parking restriction starts to the time they can issue the ticket? This ticket was received in California, thank you!
