In cali the calibration isn't every day, it's more like every three days. And you dont have to axe for the cal. report when he issues the ticket, you can take him to court and then axe for it. BTW did you say, out loud, the speed you were going. For example:
CHP "How fast do you think you were going"
You "Im not sure, I think about 85, but my speedo is messed up"
If you did then you just shot yourself in the foot. They press the button to their radio when they ask you and it gets recorded. My dad is a cop over here in Folsom, so I know a bunch of random police stuff (cali anyway)
PS You were speeding and got a ticket that you desserved, my advice is to just man up to what you did and accept the punishment, its not like they're going to send you to federal pound you in the *** prison or anything
