The Ohio Manual of Uniform Traffic Control Devices (OMUTCD)

provides standards and guidelines for the use of traffic signs,

pavement markings, traffic signals, and other traffic control

devices in our state. The Manual applies to all roads open to

public travel in Ohio.

Traffic signs are addressed in Part 2 of the OMUTCD. Chevron

Alignment Signs, which are commonly referred to as

Chevrons, are discussed in Section 2C.09 from Chapter 2C –

Warning Signs and Object Markers.

Section 2C.09 Chevron Alignment Sign (W1-8)

Standard:

The use of the Chevron Alignment (W1-8) sign (see Figure 2C-1 and Figure 2C-2) to

provide additional emphasis and guidance for a change in horizontal alignment shall be in

accordance with the information shown in Table 2C-5. [ See pages 2 and 3 attached. ]

Option:

When used, Chevron Alignment signs may be used instead of or in addition to standard

delineators.

Standard:

The Chevron Alignment sign shall be a vertical rectangle. No border

shall be used on the Chevron Alignment sign.

If used, Chevron Alignment signs shall be installed on the outside of a

turn or curve, in line with and at approximately a right angle to

approaching traffic. Chevron Alignment signs shall be installed at a

minimum height of 4 feet, measured vertically from the bottom of the

sign to the elevation of the near edge of the traveled way. [ Refer to OMUTCD Section 2A.18 for the minimum height requirements for other signs. ]

Guidance:

The approximate spacing of Chevron Alignment signs on the turn or curve measured from the

point of curvature (PC) should be as shown in Table 2C-6. [ See page 3 attached. ] If used, Chevron Alignment signs should be visible for a sufficient distance to provide the

road user with adequate time to react to the change in alignment.

Standard:

Chevron Alignment signs shall not be placed on the far side of a T-intersection facing

traffic on the stem approach to warn drivers that a through movement is not physically

possible, as this is the function of a Two-Direction (or One-Direction) Large Arrow sign.

Chevron Alignment signs shall not be used to mark obstructions within or adjacent to the

roadway, including the beginning of guardrails or barriers, as this is the function of an

object marker (see Section 2C.63).

For Additional Information . . . Please refer to Chapter 2C of OMUTCD Part 2 for

additional information regarding use of Chevron

Alignment Signs and other Horizontal Alignment

Warning Signs.
