Markings on highways have important functions in providing guidance and information for the road user. Major marking types include: |
| |
- pavement and curb markings
- object markers
- delineators
- colored pavements
- barricades
- channelizing devices
- islands
|
|
| In some cases, markings are used to supplement other traffic control devices such as signs, signals and other markings. In other instances, markings are used alone to effectively convey regulations, guidance, or warnings in ways not obtainable by the use of other devices. Under most highway conditions, markings provide important information while allowing minimal diversion of attention from the roadway. |

| A "No-Passing Zone" at a horizontal or vertical curve is warranted where the sight distance as defined in Section 3B.02 of the Ohio Manual of Uniform Traffic Control Devices (OMUTCD) is less than the minimum necessary for safe passing at the prevailing speed of traffic. |
| |
| No-Passing Zones may be marked at rural and urban intersections when engineering judgment so dictates. The decision as to whether or not a No-Passing Zone should be marked is a matter of discretionary engineering judgment. There is explicitly no requirement under the OMUTCD that No-Passing Zones shall be marked at intersections, notwithstanding the provisions of any other section of the OMUTCD. |
