I was pulled over once for an obstructed plate, but it was an officer fishing for a violation. He claimed that having a hitch ball mounted in a step bumper obscured the plate and made it unreadable. I explained to him I was the original owner of the then 15 year old truck and the bumper was OEM. The same truck, bumper and hitch ball had traveled both coasts of the US plus Canada and Mexico without issue, until now. Although he did not admit to an error, my vehicle and documentation was clean so I was not cited. I still drive through this town often and have not had incident in the past 11 years nor have I seen this officer.
