are you prepared to risk costs?
After a trial probably £400-£600.
No, the fine would be an additional amount. Probably around £100-£300 plus costs.
Oh well, the chances are never really very good.
S36 RTA is an offence of strict liability. Come what may, you went through a red light.
The only challenge is that the lights were not displayed as the law requires and various cases have been very damaging upon that point.
They only have to show that the lights were displayed in such a way that the reasonably observant motorist would have understood they applied to him.
If they can get over that hurdle their obligations are met.
Whether they can or not depends really on the physical location and the layout.
Also, you need to bear in mind that Magistrates are generally biased in favour of the Crown.
Can I clarify anything for you?
I think you are right in these circumstances.
It is not usually worth the risk.
