The minimum size for multi-lane conventional highways and expressways shall be 48 inches per The standard size of the R1-2 sign for single lane conventional highways shall be 36 inches per side. For a yield-controlled channelized right-turn movement onto a roadway without an acceleration lane and for an entrance ramp onto a freeway or expressway without anĪcceleration lane, a No Merge Area (W4-5P) supplemental plaque may be mounted below a R1-2 sign when engineering judgment indicates that road users would expect an acceleration lane to be present. The Yield Sign (R1-2) shall be authorized for use when it is necessary to assign the right-of-way but when a full stop is not necessary at all times however, it should not be used when anĪdequate acceleration lane is provided. The Ramp Yield Sign (R1-1-4) shall be used in work zone traffic control situations that require roll up signs. The Ramp Stop Sign (R1-1-3) shall be used in work zone traffic control situations that require roll up signs. The 36 inches x 18 inches sign is to be used with a 36 inches x 36 inches Stop Sign and the 48 inches x 24 inches sign is to used with a 48 inches x 48 inches Stop Sign. When used, the R1-1-2 sign shall be installed directly above the Stop The Ramp Sign (R1-1-2) may be used with a temporary Stop Sign (R1-1) installed on a ramp to control ramp traffic in a construction area. When used, the R1-1A sign should be positioned on the right side of the applicable lane. The Right Lane Keep Moving Sign (R1-1A) may be used at a signalized intersection where the right-turn lane is channelized through the turn and becomes an added lane on intersecting roadway. If necessary, the size of the R1-1 sign should be increased so that any other sign installed back-to-back with it remains within the edges of the R1-1 sign. A sign that is mounted back-to-back with a R1-1 sign should stay within theĮdges of the R1-1. Only be used for alleys with restrictive physical conditions and vehicle usage that prohibits the installation of the standard size R1-1. The standard size R1-1 sign shall be 30 inches x 30 inches for single lane conventional highways and 36 inches x 36 inches for multi-lane conventional highways. Approval to install R1-1 signs in work areas shall not require the approval of the Department of Transportation or local authorities when the conditions stipulated in the Department of Transportation's Temporary Traffic Control Guidelines are satisfied. Before local authorities designate any highway as a through highway or stop intersection which will intersect or affect a State-designated highway, approval of such designation shall first be obtainedįrom the Department of Transportation. At intersections whereĪll approaches are controlled by an R1-1 sign, a supplemental ALL-WAY Plaque (R1-3P) shall be mounted below each R1-1 sign. The R1-1 sign is also authorized for use in work zones involving one-lane, two-way roadways. The Stop Sign (R1-1) is authorized for use on those streets or highways which intersect with a through highway or at a stop intersection so designed by the Department of Transportation with reference to State-ĭesignated highways or local authorities with reference to highways under their jurisdiction. Class 2 Reflective: Class 2 reflective is referred to as engineer grade and is commonly used for non critical, non regulatory applications that still require high visibility.(a) Justification.This would include all street signs, speed limit signs and roadwork signage. All signs used on a public road must be Class 1 to comply. Class 1 Reflective is best suited for high intensity reflective signage and vehicle applications as it reflects light from wide angles. Class 1 Reflective: Class 1 reflective is the higher grade of reflectivity, and it is identifiable by its honeycomb pattern. All signs are suitable for inside and outside use. ACM signs are rigid, heavy duty and great for permanent use inside and outside in all weather conditions. All signs come with radius corners and 4 pre-drilled holes in each corner ready for mounting.
