So I just left my house and stopped at a STOP sign from my street turning left (it was not an all-way stop). I stopped and checked my right then left and did not see any cars and started my turn. All of a sudden a jeep appeared to the right of me about 3 seconds later driving very close. I glanced at him and thought how is that possible. The jeep did not honk or signal for me to stop so I continued down the second street and stopped before a main road to merge with traffic. My eyes were on the traffic to see if I can turn left. An opening came up and I turned left. I checked my rear mirror and saw the jeep following me. I thought to myself perhaps he was having road rage. I slowed down because I was coming up towards a red light and he pulled up beside me, honked, and flashed a badge. So I turned towards the right lane and stopped. He flashed his badge quickly again, I only saw "constable" and he started to tell me "where did you learn to drive like that, what if there were children. you did not check for me coming through and you turned from your side street; " and told me to get my license and proof of insurance. I stumbled because I was nervous and he kept telling me to hurry it up because "does it look like I have a lot of time?" I told him I checked my right and did not see him. He replied that if I checked I would have seen him. He then asked me whether I would be home in the evening because he would charge me. I asked him what are you charging me with as well as what time, he just ignored me and went off. At the moment I am waiting for him at my house, confused. I don't understand first why I did not see him. I checked my right after stopping. Also, if I did not see him would he not have crashed into me whether than pulling next to me 3 seconds after I successfully turned? (The curb on both sides of the street that I turned into can only fit 2 lanes but it expands into places where people can park) Would it be possible he was driving much faster than the 40km/h in the residential area and I missed him? Would he be just pissed off because I cut him off by accident? At this point I don't even know what he is charging me with. Some insight would be very much appreciated. Thanks for reading.
