This is a list of links to state Department of Transportation pages explaining their speed zoning policies. The ITE has developed a “majority rule” pamphlet like the one used by Arizona, Kansas, and Missouri.
Many states have rational guidelines for setting speed limits. However, these guidelines are seldom followed, because of political and revenue generating objectives. The police officers in each state are not responsible for setting these policies, but they are obligated and pressured to enforce them.
