I. No person shall drive any vehicle on a highway in any race, speed competition or contest, drag race or acceleration contest, test of physical endurance, exhibition of speed or acceleration, or for the purpose of making a speed record; and no person shall in any manner participate in any such race, competition, contest, test or exhibition.

As mentioned before, bragging on social media, posting Strava records to back it up.

II. The driving of 2 or more vehicles from a point side-by-side at accelerating speeds in a competitive attempt to outdistance each other, or the driving of one or more vehicles over a common selected course, where the starting and finishing points are the same, for the purpose of comparing the relative speeds or power of acceleration of such vehicle or vehicles within a certain distance or time limit on a highway is prohibited.

This is pretty much the definition of the Wednesday night "Hammerfest"...

If you go back a post of mine, you'll see that I backtracked a bit and said that while it might get dismissed in court or tossed out by a DA before even going to court, laws are such in NH that a cop could certainly cite based on statutes. Then again, there are certainly legitimate ways this could be prosecuted if a DA thought it might score them political points and they thought they could win.


III. The use of one or more vehicles in an attempt to outgain, outdistance, or prevent another vehicle from passing, to arrive at a given destination ahead of another vehicle or vehicles, or to test the physical stamina or endurance of drivers over long distance driving routes on a highway is prohibited.

Note that this specifically refers to the "physical stamina or endurance" of drivers.
