Over the next 4 weeks, I will be driving close to 5100 miles not counting daily 40 mile commute and misc. miles. From Ames/Ankeny areas to Tulsa OK, Burlington IA, Estes Park CO, Madison WI, Minneapolis MN, & Overland Park KS. Mostly interstate miles. How many miles over the posted speed limit in IA, MO, KS, OK, NE, CO, WI & MN is generally safe to drive without getting a ticket? Every extra mph I can average will cut my driving time 1.5-2hrs roughly.
