I got a speeding ticket at school area. I am sure I wasn't speeding. I was driving on a road where the speed limit changes from 35mph to 20mph within about 15 yards. I thought the officer tested my speed just before I entered the 20mph zone. I have a passenger. He noticed my speed was 20 when entering the school area. I chose to contest. I have several questions. I do appreciate if you experts can help with them.
I need to send discovery request. I didn't get a case number yet. Should i wait to do the request after receiving the court date notice and case number?
Do I need to ask for deferral? If so, should i do that before court or after court?
Do I need to contact the court for asking my passenger to be a witness? What's the procedure to ask for a witness?
