No, the officer is not required to show you the radar readout. From a safety standpoint, it is unwise to let you out of the car.You can argue in court that you asked to see the device and was refused and on that basis you are challenging the officer assertion that you were speeding. The court will tell you there is no right to endanger the officer or yourself just to view the radar readout. The court will accept the word of the officer that you were speeding. Your contention that you weren't ". . .paying attention to my speedometer. . ." is not a defense. Pay the ticket, save yourself some grief.
