Traffic Light Check-In turns the universally understood red/amber/green metaphor into a two-part emotional check-in. Each person states a colour for how they feel plus one sentence of why. Green forces you to reaffirm what is working; red or amber names a struggle out loud. Run repeatedly, it builds a baseline for each person, so a green regular who suddenly goes red three days running becomes a visible signal that something has changed. It works because it is fast, requires no jargon, and gives both the individual and those around them a shared vocabulary. Alex George uses it in schools; ICU nurses used it at shift handovers in the pandemic so matrons could direct support to the most burnt-out staff.
Origin
Dr Alex George developed the Traffic Light Theory for his book The Mind Manual and road-tested it in schools and universities across the UK. Intensive care nurses independently adopted it during the pandemic to flag burnout at shift handovers.
Core principles
- 01You cannot support what you cannot see
- 02A shared, universal language lowers the bar to disclosure
- 03Change from someone's baseline is the real signal, not the absolute state
- 04Naming an emotion is the first act of managing it
- 05Everyone at the table learns what builds and drains mental health
How to run it
- 1
Pick a recurring moment
Choose a regular touchpoint like a family meal, the end of a shift, or the start of a team meeting so the check-in becomes a habit rather than a one-off.
Pro tip It takes only a few moments, so protect it from being dropped.
- 2
Everyone names a colour
Go round the group and each person says red, amber or green for how they feel today.
Pro tip For children you can swap in cloudy, rainy or sunny.
- 3
Add one sentence of why
Each person gives a short reason for their colour, such as poor sleep, a recurring stress, or a good workout.
Pro tip Naming a green reaffirms the habits that keep you well.

Watch for baseline shifts
Over time you learn each person's normal. Flag anyone who moves off their usual colour, especially a green who turns red for several days.
Watch out The signal is the change from their normal, not the colour in isolation.

Act on the reds and ambers
Ask a good question, listen to the answer, and resolve the cause, for example someone who has worked eight days straight gets time off.
Pro tip Often the solution presents itself once the person is simply asked.
Watch out Doing the check-in and ignoring the answers erodes trust.
In the wild
During the pandemic, intensive care nurses ran red/amber/green at the end of handover shifts. Nurses saying red after five days straight were quickly identified, letting senior matrons focus support on the most burnt-out staff before they broke down.
→ Early identification of burnout and targeted support for struggling staff.
Common mistakes
Doing it once then forgetting
Ali admits his team tried it once in a meeting, found it helpful, then dropped it. Without discipline the baseline never forms and the signal is lost.
Only stating the colour
Skipping the one-sentence why removes the learning; you never establish what actually drives good or bad days.
Is it for you?
Best for
Families, small teams and high-pressure units who want a fast, repeatable way to catch struggles early.
Not ideal for
Deep clinical assessment or anyone needing formal diagnosis rather than a check-in.
From the transcript
“we'd go around we'd say red Amber or green how you're feeling today”
“if this person that was maybe green a lot of the time suddenly becomes red maybe three or four days in a row it makes…”
