Yesterday I was given a ticket, I was making a right turn at a light and the light turned red. However, the officer wrote me up for a 21453(a) which is running a red light. I should have been wrote up for 21453(b): After stopping, may turn right, or turn left from a one-way street to a one-way street, (unless sign posted) but shall yield to pedestrians and traffic on cross street.
The light did not have an arrow signal, and their was no sign that states "no right turn on red"
Is there anyway I can change this? Would I have to go to court and then come back again in order for the officer to ok it? I heard that sometimes the judge will just throw it out, is this true? Also, On another site someone posted that if you challenge it then you lose your chance to go to traffic is this true as well?
