How school zone speed limits are set

Thornton establishes school zone speed limits through the municipal code and traffic orders that designate certain road segments and times as school zones. The city typically bases posted school zone speeds on engineering and traffic studies, signage standards, and coordination with local school districts. The official municipal code lists the process for establishing speed regulations and the authority to post reduced limits; consult the Thornton Municipal Code for the controlling ordinance text.Thornton Municipal Code[1]
