PTRD covers which paths?

PTRD covers which paths?

• A. All roads accessible to the public, both on and off the installation; railroad lines for passenger or cargo traffic; water channels capable of being used for commerce.
• B. Air routes used by military flights
• C. Private roads only
• D. Off-installation roads only

Answer: (A)

PTRD focuses on every transportation path that connects to the public and the commercial transportation network, because those routes represent the real-world pathways where hazardous materials can move and where security and safety measures must be applied. It includes roads that the public can use, whether they’re inside or outside the installation, as these are common, accessible routes for movement. It also covers railroad lines used for both passengers and cargo, since rail corridors carry material through communities and near facilities. Water channels capable of commerce—rivers, canals, and similar waterways—are included because ships and barges can transport loads along these routes as well. This broad scope ensures that all practical pathways for movement are considered for planning, risk assessment, and protective actions. Air routes aren’t part of PTRD in this context, and private or purely off-installation roads would miss on-site public access and intermodal links, which is why the inclusive option is the best fit.
