Missing or Encroached Buffers

The buffer space that separates traffic from the work or a hazard is missing, too small, or occupied by equipment.

Last reviewed: June 24, 2026

What It Looks Like

  • No buffer between traffic and the work, or a buffer used to store equipment, materials, or workers.

Why It Happens

  • Space was tight and the buffer was skipped, or it was treated as usable work area.

Why It Matters

  • The buffer is the margin for error; without it, an errant vehicle reaches workers or the work immediately.

How It Is Identified

  • An inspection checks for the planned buffer and that it is kept clear.

How It Is Corrected

  • Establish the buffer per the plan and clear it of equipment, materials, and workers.

How It Can Be Prevented Upstream

  • Show buffers on the plan and keep them clear as a rule in the field.
