Colorado and Kansas part ways on 7 of 9 rules we track: phone law, learner's permit age, car insurance, car sales tax, car inspection, new resident deadline and lane splitting.
Heading from Denver to Wichita takes you across the border, and 7 of the nine laws differ once you cross. Main routes include I-25 on the Colorado side and I-70 in Kansas; the capitals, Denver and Topeka, set the laws for their side.
The largest difference: newcomers get 30 days in Colorado but 90 days in Kansas ahead of the first deadline. Residents of Colorado Springs who travel to Overland Park, or vice versa, deal with both rulebooks: Colorado's on I-70 and Kansas's once they cross on I-35.
