It’s no big deal to go five or ten miles over the speed limit, is it? Highway traffic safety officials set speed limits for a number of reasons. First, when traffic is traveling at a steady speed, drivers have a better idea of what to expect from other drivers. If you’re behind the wheel and moving much faster or slower than traffic, you have the potential to confuse the drivers around you, creating a higher potential for someone to do something unpredictable and cause a crash.
Another element in setting appropriate speed limits is the design of the road. Obviously, residential streets and interstates are going to have different speed limits. To help maintain consistency from town to town, the Iowa legislature has set standard speed limits (known as statutory speed limits) for some types of roads. These can be found in Iowa Code 321.285.
