Where do speed limits come from?
Speed limits are under the jurisdiction of the state government. The Ohio Revised Code (ORC) establishes general speed limits for different types of roadways in section 4511.21. Some examples of the ORC applied to municipal areas are listed below:
-
15 mph on an alley
-
20 mph in a school zone (during restricted hours on school days)
-
25 mph on a local (non-through) street or on a street within a business district
-
35 mph on through routes
-
55 - 65 mph on freeways

School zones
School zones are defined as a section of roadway fronting a school between the school property lines projected to the street. School zones are in effect during school recess and while children are going to or leaving school during the opening or closing hours. The speed limit in a school zone is 20 mph. The typical morning and evening times that school flashers operate on normal school days for Dublin City Schools within the Dublin city limits are as follows:
Elementary Schools:
8:25 - 9:25 am and 3:10 - 4:10 pm
Middle Schools:
7:45 - 8:45 am and 2:25 - 3:25 pm
Elementary and Middle School shared sites:
7:45 - 9:25 am and 2:25 - 4:10 pm
High Schools:
6:55 - 7:55 am and 1:15 - 3:15 pm

Speed limit changes
If a speed limit established by the ORC is not appropriate for a certain location, an engineering study may be submitted for consideration to the Ohio Department of Transportation. Upon review and approval from the state, the speed limit may be changed. The study includes data such as existing travel speeds, roadway character, development density, and crash history. The state has the authority to approve or disapprove any speed limit change request they receive.
