We are not in a position to see how your car was situated on the road after the accident. If the officer contends that it was positioned in a manner that impeded or blocked the normal and reasonable movement of traffic, and you contend that it did not, you can dispute the ticket and ask a court to decide whether or not you were impeding traffic.
If you provide more information about exactly where your car was located relative to the traffic lane, and what would have been accomplished to improve the flow of traffic had you followed the officer's instruction, we will be in a better position to comment on the validity of the ticket.
