Which book and table should be referenced for the advance placement of warning signs?

• A. FHWA Manual
• B. MUTCD
• C. AASHTO Green Book
• D. Traffic Control Devices Handbook

Answer: (B)

The correct reference for the advance placement of warning signs is the Manual on Uniform Traffic Control Devices (MUTCD). This manual is a comprehensive guide that establishes national standards for traffic control devices, including warning signs, regulatory signs, and pavement markings used on public roads in the United States.

The MUTCD provides detailed guidance on various aspects of traffic control, including the recommended distances for the advance placement of warning signs relative to the location of the hazard being indicated. This ensures that drivers have adequate notice of upcoming conditions or hazards, which enhances safety on the road.

Other references like the FHWA Manual, AASHTO Green Book, and Traffic Control Devices Handbook may offer valuable information on traffic control, but they do not serve as the primary source for the standardization and specific requirements related to the advance placement of warning signs as outlined in the MUTCD.
