Does an officer have to write a reckless driving ticket in addition to a speeding ticket for more then 40 over the posted speed limit in il?

In Illinois, if an officer observes a driver exceeding the speed limit by more than 40 mph, they are required to issue a reckless driving ticket in addition to the speeding ticket. This is because driving at such excessive speeds is considered a form of reckless driving under Illinois law. The officer has discretion in certain circumstances, but typically, both charges would be applicable.
