This is not really a speed trap, just a revenue generator for Carlsbad police. Across from Marie Calendars is a traffic island cut-through left turn lane posted no U turns. People leaving the McDonalds just to the south with no left turn exit option often enter this left turn lane and U-turn to return to Palomar Airport Rd. The motorcycle cops hide at lunch time behind the bushes down low in the business across from Marie Calendar’s and bust the U-turners. Watch out, and go to the next cut through (100 yards further) that is not posted.
