Nope... The graduated speed versus fine schedule is set up as follows:
1 to 15mph over the limit - a fine of approximately $230
16 to 25mph over the limit - a fine of approximately $355
26 and higher over the limit - a fine of approximately $475
So 66 or 67 and regardless of whether the limit used as the basis is 55 or 65, it still falls in the "1 to 15 over the limit" bracket, which carries an approximate fine of $230 or so...
In all honesty, I wouldn't put so much weight on what the officer stated during the stop. I mean even if you bring it up in court, and while they often do especially when it comes to speeding citations, he is under no obligation to give you any sort of break; and bringing it up is not likely to change the outcome much if any at all.
In my opinion, it really boils down to: how it gets filed with the court, what speed limit and alleged speed you get arraigned on, and how he might describe the violation in court during his testimony or if you bring it up on cross, because those will end up factoring into what type of defense argument you might have, at which time, whether he gave you a break or not becomes immaterial.
Sorry, but I now realize that in addition to asking you to verify the code section, I should have also asked you to describe the highway you were on. Is it a 2 lane undivided highway -1 lane in each direction with or without a passing lane in the middle-??? (You only mentioned a 55mph limit and I made an assumption that I should have asked you to confirm...)
