Big risk.I've heard on the rumour mill that it's often worth taking it to court as the Police generally don't turn up and therefore the prosecution is quashed.
If you don't take the fixed penalty the fine will be based on your income.
If you earn £350 a week, then the fine will be (if convicted) £175, plus costs in the region of £50, plus £15 victim surcharge.
Do you feel lucky?
