I somewhat agree to timebandit, its ruthless for a driver who's being paid only 500-700 Riyals monthly, and in any countries whether the fine is high or low, there is a proceedings for such acts which I feel missing here, instead of making it a high class choice to break the lights and killing weaker, they should enforce a fair and square judiciary which will decide whether he has to pay the full fine and/or was a genuine mistake and shouldn't be influenced by any means. This could be in cooperated with some extensive policies like the insurance will be high for such vehicles and/or drivers, resulting even though they break it they will face the consequences afterwards.
I am strongly against mad fines and I believe it will never do good to enforce the law.
