I have gotten a good many speeding tickets and have never had my insurance rates affected. I had a guess to the reasons why, my guess has been confirmed.
Source: (around page 9) "By comparison, speeding-related citation data is not as frequently collected or maintained in a statewide data-base. In response to the question of maintaining speeding-related citation data, 31 jurisdictions (AL,AK, CA, CO, CT, DE, FL, GA, Guam, HI, IL, IA, KY, LA, MD, MA, MS, NC, NV, NH, NJ, OK, SC, SD, TN, TX, VA, WA, WV, WI, WY) responded in the affirmative. Many of the affirmative responses stated that citation database information is only maintained on citations issued by the state police and does not include speeding citations issued by local enforcement agencies. "
As long as it is not a state trooper in TN, GA, LA, MS, and TX. Thank goodness for the south being too poor to do anything about speeding tickets.
NOTE: I expect this situation to change as technology becomes cheaper.
