If you pay it keep in mind you'll get points on your record. Also anything over 85 is criminal speeding even if the speed limit is 75.
RCW 46.61.465 defines reckless driving as The unlawful operation of a vehicle in excess of the maximum lawful speeds provided in this chapter at the point of operation and under the circumstances described shall be prima facie evidence of the operation of a motor vehicle in a reckless manner by the operator thereof.I think it depends on the state. WA you can go 100 over and it isn't criminal. It becomes criminal if the cop writes you a ticket specifically stating that type of infraction (i.e. negligent driving, reckless driving, etc).
