Iowa joins a growing trend of states with large empty stretches: For traffic safety purposes, the more frequently people stop, stretch, and take their eyes off the road, the better. Adding Wi-Fi at rest stops is just one tool in that arsenal, but it's also a nice idea for tourists, truckers, and business travelers. Iowa will equip a total of 40 locations by July; 20 of them by mid-March.
A trial set of eight locations had 111,000 access over seven months. Several stops are active on Interstates 35 and 80. Service will be free and operated by I-Spot.
