I was stopped by a police car on the motorway and charged with an offence. I told the police officer that I didn’t agree with him, but was never cautioned or told of my right to silence. The officer’s witness statement makes reference to two comments I made in response to the charge. What’s my legal position?
It’s unlikely you were actually charged with an offence unless you were taken to the local police station. It’s more likely that you were told you were being reported; in which case (since you have a copy of the officer’s statement) you have probably received a summons. If you weren’t cautioned, what you said at the time may be subject to challenge.
