"Not speeding" is no guarantee of not getting a ticket - not when radar is treated as infallible but, yet, it IS quite fallible.

If reasonable speed laws were posted, this wouldn't be a problem.

Here in NH, we had a big project (Nashua's "Exit 2" as part of the US-3 widening through town) that built an extra bridge across the Merrimack River between Nashua and where I live in Hudson. Previously, it was a 1-mile or so 2-lane bridge that ended at "T" intersections on either side with traffic lights because each end was a connection to a major road (the Daniel Webster Highway in Nashua, and NH-3A in Hudson).

After the project, there were TWO THREE-lane bridges (one for each direction) with a much larger intersection (with dedicated turning lanes) in Hudson at NH-3A and onn/off ramps for the DW Highway in Nashua - and the "bridge" continued on to join up with a huge new "Exit 2" on "the turnpike" (US-3).

Speed limit for 2-lane secondary road: 55MPH

Speed limit for 6-lane expressway: 45MPH

And in D.C., which I drove through this past July and August.. Speed limit for I-395, 6-lane expressway with no traffic on a Saturday morning: 45MPH (I got a ticket via photo radar for doing 56MPH)
