going south on san pedro is a school crossing warning sign and about 2 more blocks one can see ahead to a flashing school zone light that appears to be linked to the school crossing warning sign. however, immediately past the crossing is a 20 mph school zone speed sign that does not flash and is shaded by a large tree and that begins the school zone–not the flashing school zone light ahead. the officer said there were two school zones and the flashing light ahead was a different. approaching these school zones while driving north on san pedro, the driver encounters the flashing school zone light which appropriately marks both school zones. going south, however, the flashing light marks only the second school zone. when i got my ticket there were at least 3 motorcycle cops who were onto southbound drivers like flies on honey. i could not believe i was getting a ticket because i had already gone through the northbound section of the school zones and was prepared to slow down to 20 on my return trip while looking ahead to the flashing light which was not, in actuality, the true beginning of the southbound school zones. i was so stunned that i could have missed the school zone speed sign that i drove back around 3 times to assure myself of my mistake (and saw the cops give out at least 10 or more tickets at that same place). if ever i have encountered a deliberate speed trap, this was it. acknowledging that this section is mismarked, the city should be concentrating on the safety of the children by correctly marking this area with a visible flashing sign rather than playing cop games at the expense of safety. after properly marking this area, then the cops give tickets to speeders who disregard the flashing signage.
