Street Sign Retroreflectivity Audit Logger
Night-and-day sign audit log — MUTCD retroreflectivity checks, damage, obstruction and post condition, GPS-tagged and fully offline.
New street sign inspection
Agencies using the MUTCD visual assessment method run nighttime inspections on a 1–2 year cycle by district.
Field guide: Street Sign Retroreflectivity Audit Logger
A stop sign that's invisible at night is a liability the courts take seriously — US tort cases routinely turn on whether an agency had a sign maintenance method and followed it. The MUTCD requires agencies to maintain minimum retroreflectivity using one of several assessment methods; the most common is a trained-observer nighttime visual inspection, which is exactly what this logger structures.
Record the sign series, sheeting grade and a pass/marginal/fail call from the nighttime drive, plus daytime physical defects (delamination, vandalism, vegetation, leaning posts). Install-year capture supports the 'expected sign life' method as a cross-check. The export gives you a replacement list sorted by regulatory priority — STOP and YIELD failures first.
Field tips
- Run night checks with low-beam headlights from the approach lane at posted speed — that's the condition the standard contemplates.
- Engineer-grade sheeting on a 15-year-old sign almost never passes; flag by age even if it looked acceptable in dry conditions.
- Log obstruction findings (trees, parked trailers) separately from sign failures — they're a trim crew's work order, not a sign shop's.
Records are stored only in this browser (localStorage) — export regularly. This tool aids field documentation; it does not replace your agency's official inspection procedures or engineering judgment.

Frequently asked questions
What are the MUTCD minimum retroreflectivity levels?+
MUTCD Table 2A-3 sets minimums by sign color and sheeting type — for example, white-on-red signs like STOP must retain at least 7 cd/lx/m² on the red background. Agencies don't have to measure every sign; they must use an approved maintenance method such as visual nighttime inspection, expected life, or blanket replacement.
How long does sign sheeting actually last?+
Engineer Grade (Type I) typically fades below minimums in 7–10 years; High Intensity prismatic in 10–15; Diamond Grade in 15+ depending on sun exposure and orientation. South-facing signs degrade fastest in the northern hemisphere.
Do I need a retroreflectometer?+
No — the MUTCD explicitly allows the trained-observer visual method using calibration signs. A retroreflectometer is useful for marginal calls and for defending the program, but a consistent nighttime inspection log like this one satisfies the method requirement for most agencies.
Which sign failures are urgent?+
Regulatory signs that assign right-of-way — STOP, YIELD, DO NOT ENTER, ONE WAY — get same-week replacement at most agencies, and a downed STOP sign is a same-day emergency with temporary signage. Warning and guide signs follow on normal work-order cycles.
