The correct answer is D) The current fines are not high enough to discourage drivers from going through red lights.
The detail that is relevant for an argument to make drivers who run through red lights pay a fee is "The current fines are not high enough to discourage drivers from going through red lights."
It is relevant because although already exists a fee for drivers who run through red lights, it is not so high because they still doing that and it is against the law and the worst part is that they can cause a fatal accident. So this is very dangerous and people should take this seriously.
That is why it is important that penalties should be harsher in order to force people to stop doing this. They are risking their lives and other people's lives.
