School Zone Speed Limit
House Bill 2840 (2005)

In 2003 the Oregon legislature made sweeping changes to Oregon school speed laws.  The law defined three categories of school zones:
  • Lower speed roadways adjacent to the school grounds (30 mph or less); or
  • Higher speed roadways adjacent (35 mph or greater); or
  • School crosswalks away from school grounds. 
The different options for posting including: “At All Times”, “School Days XX AM to XX PM”, “When Flashing”, and “When Children are Present” depending on whether the roadway was adjacent or not adjacent and low or high speed.
In 2005 the Oregon legislature acted to simplify the school laws under House Bill 2840.  The Governor signed the bill into law on July 20, 2005.
The new law does away with the "At All Times" school zones -- it goes into effect on July 1, 2006. You may see the "At All Times" signs after July 2006, the new signs should be posted before the end of August.
The new law has only two categories of school zones those adjacent and crosswalks not adjacent. 
School zones on roadways adjacent to school grounds can be either:
  • “When Flashing”; or
  • “School Days 7AM to 5PM”
Those school zones at a school crosswalk away from school grounds can be either:
  • “When Flashing”; or
  • “When Children are Present”
