Iowa law on stopping for school buses
The greatest risk is not riding the school bus, but approaching or leaving it. So, children need to be especially careful around the school bus "danger zone," which is 10 feet in front, behind and on each side of the school bus.
Legal operation of snow mobiles
For safety purposes, it is recommended that snowmobiles be operated on private property with the landowner’s permission or on trails designed by the DNR for the operation of snowmobiles.
Move over or slow down law
Not just a courtesy, it’s the law. Move over or slow down to keep everyone safe!
Rail safety
Protecting the safety of motorists, pedestrians and train passengers is an important role of the Iowa DOT's Office of Rail Transportation. Toward that goal, the office manages a number of programs and activities that encourage safety.
Road rage
There is no national definition for the term "road rage". However, it is commonly defined as a societal condition where motorists lose their temper in reaction to a traffic disturbance.
Roundabouts
In recent years, roundabouts have been used in the United States to reduce crashes, traffic delays, fuel consumption, air pollution, and construction and maintenance costs.
Rural road crashes
Crashes on rural roads occur at more than twice the rate of crashes on state roads. Driving too fast for conditions is the number one reason for rural road crashes.
Safe Routes to School
During the past two to three decades, there has been an incredible rise in obesity and physical inactivity in children and adults. The impact on health and health-care costs is high and will continue to rise dramatically.

Safety programs

Highway Safety Improvement Program (HSIP)
Iowa DOT collaborated with Iowa County Engineers Association to continue a safety program for the county road system under a new name, HSIP – Secondary Program. The HSIP – Secondary Program will provide a $2 million set-aside from the HSIP.
Horizontal Curve Sign Program
The intent of the Horizontal Curve Sign Program is to provide funding to counties for the purchase of curve warning and chevron signs. Funds can be used to reimburse counties for purchases of advance warning signs, advisory speed plaques, chevrons and arrows.
Iowa Strategic Highway Safety Plan (SHSP)
SHSP is a statewide-coordinated safety plan that provides a comprehensive framework for reducing highway fatalities and serious injuries on all public roads.
Overhead Flashing Beacon Replacement Program
