620.10.1 Longitudinal Rumble Strip Markings (MUTCD Section 3K.01)
Support. Longitudinal rumble strips consist of a series of rough-textured or slightly raised or depressed road surfaces intended to alert inattentive drivers through vibration and sound that their vehicle has left the travel lane. Shoulder rumble strips are typically installed along the shoulder near the travel lane. On divided highways, rumble strips are sometimes installed on the median side (left-hand side) shoulder as well as on the outside (right-hand side) shoulder. On two-way roadways, rumble strips are sometimes installed along the center line. See Standard Plan 620 for details.
EPG 620 contains no provisions regarding the design and placement of longitudinal rumble strips. The provisions in EPG 620.10.1 address the use of markings in combination with a longitudinal rumble strip. Figure 620.10.1 illustrates markings used with or near longitudinal rumble strips.
Rumble strip markings provide notice to the driver that they are leaving their lane. They also provide increased visibility of the pavement markings during wet pavement conditions. Rumble strip markings are a system-wide safety improvement. Additional information on the use and application of rumble strip markings can be found in EPG 626.
Standard. Where edge line or centerline rumble strips are required, as noted in EPG 626, the edge line or center line marking shall be located over the rumble strip to create a rumble stripe.
The color of an edge line or center line associated with a longitudinal rumble stripe shall be in accordance with EPG 620.1.3.
620.10.2 Transverse Rumble Strip Markings (MUTCD Section 3K.02)
Support. Transverse rumble strips consist of intermittent narrow, transverse areas of rough-textured or slightly raised or depressed road surface that extend across the travel lanes to alert drivers to unusual vehicular traffic conditions. Through noise and vibration, they attract the attention of road users to features such as unexpected changes in alignment and conditions requiring a reduction in speed or a stop.
EPG 620 contains no provisions regarding the design and placement of transverse rumble strips that approximate the color of the pavement. The provisions in EPG 620.10.2 address the use of markings in combination with a transverse rumble strip.
EPG 626.4 contains information related to transverse rumble strips.
Standard. Except as otherwise provided in EPG 626.4 for TTC zones, if the color of a transverse rumble strip used within a travel lane is not the color of the pavement, the color of the transverse rumble strip shall be either black or white.
Guidance. White transverse rumble strip markings used in a travel lane should not be placed in locations where they could be confused with other transverse markings such as stop lines or crosswalks.
