My question involves a traffic ticket from the state of: UT
I got a ticket for violating Utah Code Annotated 41-6a-711 which states:
41-6a-711. Following another vehicle -- Safe distance -- Exceptions.
(1) The operator of a vehicle:
(a) may not follow another vehicle more closely than is reasonable and prudent, having regard for the:
(i) speed of the vehicles;
(ii) traffic upon the highway; and
(iii) condition of the highway; and
(b) shall follow at a distance so that at least two seconds elapse before reaching the location of the vehicle directly in front of the operator's vehicle.
(2) Subsection (1)(b) does not apply to funeral processions or to congested traffic conditions resulting in prevailing vehicle speeds of less than 35 miles per hour.
This occurred at 10:30 at night and my left headlight was out. The officer was passing me going the opposite direction and I was the last car in a line of 4-5, with the one directly in front of me being a van or SUV pulling a boat.
I do not believe that I was following too closely. When I realized that the officer was going to give me a ticket I decided to ask him right there how he determined that I was less than 2 seconds behind. He stated "I didn't measure, I could just tell." He also made statements such as "I could tell by the distance of your headlight, err the lack of your headlight that you were too close"
I repeatedly got him to admit that he did not scientifically measure my distance in any way as we passed each other at 120 mph combined speed.
When I specifically said "You said you didn't scientifically measure me, you are admitting that right?" He raised his voice and said "I am not admitting anything." Then he proceeded to scream at me multiple times to shut up and completely came unglued. He told me that "The next car that comes by here and hits me, I am going to sue you"
I was being direct but not a jerk and I was using words such as sir multiple times. Before he lost it on me, I told him that I would sign the ticket but that I was just trying to understand how he determined that I was too close.
The kicker is that I have it all recorded on my phone, so I definitely have evidence that he stated that he did not measure my distance in any way.
My question is, what is the best way to get this dismissed in court? I have a little less than a month before the trial. What should I ask for in discovery? Does anyone know of a form letter I can use for a basic discovery request? Any help is greatly appreciated.
