Guide signs are essential in directing road users to their destinations. Guide signs direct road users to areas such as cities and roads or to specific facilities. Certain public and private facilities that generate significant traffic volumes are eligible for signing.
The Manual on Uniform Traffic Control Devices (MUTCD) is the primary source concerning signing along the state highway system. The Supplemental Rules for Guide Signs on Freeways, Expressways and Conventional Highways provide additional rules and regulations concerning signing along the state’s highways.
