3 Tickets At Once

hey i got pulled over last night and the cop thought my friends and i were sarcastic to him :O then he was suspicious if we used any drugs or alcohol last night but we didn't. he asked me to do a test like walking on a line and stuff liked that and i passed it. then he was pissed so he started to find silly problems about car .

1- dirty plate 110 dollars

2- improper number plate light 110 dollars

3- drive without proper headlights 110 dollars

i was wondering if these tickets have any point and how i can drop these tickets .

Thanks for your responses
