Abstract

Chevrons provide additional emphasis and guidance for drivers. If spaced properly, chevrons can delineate the curve so drivers can interpret the sharpness of the curve. Table 2C-2 of the Manual on Uniform Traffic Control Devices (FHWA 2009a) recommends the size of chevron alignment (W1-8) signs by roadway type. Several agencies, including the Iowa Department of Transportation (Iowa DOT), have applied a larger chevron size to a roadway than suggested by this table. The idea is that larger chevrons will be more prominent and visible to drivers. These larger chevrons may be particularly useful if sight distance issues exist.
