I recently received two speed camera citations, both from a unit positioned very close to my office. These cameras have been sprouting like weeds in MD; in fact, I used to pass several cameras daily on my work commute. Still, these recent citations are my two and only (knock wood).
I am opposed to speed cameras on principle (a topic for another thread) which is why I decided to waste my time contesting the two $40 fines. I requested a hearing at which that the Camera Operator would be present, via certified mail. I reviewed the relevant statute. Then, I reviewed my citations.
The first thing I wanted to do was do a back-of-the-envelope speed check. On one citation, the image quality was so blurred that I couldn’t determine the position of my car. (My “alleged” car?) The second citation image quality was marginally better, and I could see a white lane stripe visible in both photos. I used satellite mapping to estimate the average length of the lane stripes on that stretch of road (about ten feet each) and was then able to conservatively estimate that my car had moved ten feet or fewer between the first and second photo.
Unfortunately, the time stamp on the photos only breaks down to the second. Both photos were taken during the same second.* I resorted to using the small print cited on my violation, that speed readings were taken at a rate of 200 to 300 calculations per minute. I assumed the photos corresponded with two consecutive readings taken at the fastest rate, and so was able to conservatively estimate my shown speed at 34 mph.
Armed with my calculations, I headed to court. When my name was called, I explained that I was unable to verify the position of my car based on the first citation’s blurry photos, but explained the process I had used to estimate the speed of my car in the second citation’s photos. I tried to be very clear about the sources of my data and my assumptions. I also emphasized that my estimates were “conservative,” ie, the largest possible distance traveled and the shortest possible time interval calculated. Based on my estimates, the cited speed exceeded the actual speed by a minimum of twenty percent, which to me, indicates reasonable doubt** about the accuracy of the cited speed.
The judge told me my argument was “bizarre.” She also said that my estimate of 34 mph was an admission of speeding. (Argh! No! That’s why I repeated that my estimates of distance and time were conservative!) Then she reduced my fine on each to $5 plus court costs and waved me away.
Thus, my morning’s efforts netted me a savings of 2 x $13.50, or $27 total, which does not heal my wounded feelings. My methods were NOT bizarre. They were MATH.
What do they teach in schools these days?
*This was not always the case! A colleague of mine successfully contested a ticket using the distance and time displayed (fractional seconds). Apparently the citation-issuers have become craftier about not providing data with which to verify their claim.
**IANAL. Obviously.
