Missing Signs

A sign the plan requires is absent, so road users lose expected warning or guidance.

Last reviewed: June 24, 2026

What It Looks Like

  • A required advance-warning, guidance, or regulatory sign is not present in the sequence the plan calls for.

Why It Happens

  • A sign was never installed, was knocked down and not replaced, or was removed early.

Why It Matters

  • Missing warning leaves drivers unprepared for the condition ahead, a direct safety risk.

How It Is Identified

  • An inspection compares the sign sequence in the field against the approved plan and the standard.

How It Is Corrected

  • Install or replace the missing sign in the correct position and sequence.

How It Can Be Prevented Upstream

  • Follow the sign sequence on the plan at setup and check signs during daily and nighttime inspections.
