Does a foreigner need to pay a fine for violating the seatbelt law? [closed]

This event all happened about 5 minutes at 3 PM in Washington. I got a violation ticket for seatbelt when I set in the back set of private car. When we stopped our car and before the officer came, I was trying to find my husband's international driver license, so I unlocked my seatbelt, therefore I also got one ticket. The officer came to front window and asked license and said 'do you know you are overspeed?' Before he came, I set on the middle of backseat, I unbelted in order to find some stuff I need and move closer to the window when the car stopped. But the officer just ask and took our license away. When we cool down I and our mother waved our hand and try to get the officer back, but he just ignored!
