I went through on amber. There was a Police Officer who stopped me and has alleged I went through on red, so it is my word against his. Can I fight the allegation?
You can dispute the allegation, but the mere fact that the lights were not red, does not provide you with a defence. If you crossed on amber, you have still committed the offence, unless you can show that it was unsafe to stop. If the Police Officer can convince the Court that there was no reason why you should not have been able to stop on amber, you could be convicted. The fact that it is his word against yours does not prevent a prosecution, although clearly, the outcome will depend heavily on each party's version of events/credibility.
