Vertical Traffic Light Emoji

🚦 is a vertical traffic light. Red on top, amber in the middle, green at the bottom, the order that's used in almost every country that runs vehicular signals. Unicode 6.0 standardized it in 2010 as part of the Transport and Map Symbols block, right next to its horizontal twin 🚥. Most vendors show all three lamps lit at once, which is never a real-world state but reads as 'this is a traffic light' in a single glance.

People type 🚦 for four reasons. The literal one is traffic (stuck in it, waiting at a red, crossing a green). The second is decisions (three-light metaphor for 'go,' 'slow down,' 'stop'). The third is performance reviews and software dashboards, where red-amber-green statuses inherited the name 'RAG' from traffic signals. The fourth is fandom: Red Light, Green Light from Squid Game in 2021 pulled the emoji back into cultural rotation for about six months.

🚦 is the most typed of the three traffic-signals emojis by a wide margin. Google Trends shows its raw-character search volume grew from around 21 in 2020-Q1 to 95 by 2025-Q4, while its horizontal twin 🚥 stayed flat in the teens. Most usage is practical (commute updates, driving jokes, 'got caught at every 🚦'). But the emoji never became the dating-shorthand people would have predicted. When Gen Z needed a red-flag signal they picked 🚩, not 🚦, and 🚩 absolutely crushed 🚦 in search volume during the late-2021 red-flag meme explosion on TikTok. Traffic light emoji got to watch the flag emoji steal its metaphor.

The idea of a traffic light emoji is older than the internet emoji project. The world's first traffic light was installed outside the British Parliament in December 1868, designed by railway engineer John Peake Knight. It had two gas-lit arms, red and green. A few months later the gas exploded and seriously injured the policeman operating it, and the idea was shelved until electric signals caught up.

The first electric traffic signal was installed in Cleveland, Ohio on August 5, 1914, designed by James Hoge. Cleveland's version already had red and green lights and a switching system that prevented conflicting signals. The amber (yellow) middle light arrived in Detroit in 1920, patented by police officer William Potts, giving the signal the three-color format the emoji still shows today.

Unicode gave the signal a pictogram in Unicode 6.0 (October 2010), carrying forward designs from the Japanese carrier sets that had drawn traffic lights vertically since the 1990s. SoftBank and au KDDI both had a vertical traffic light pictogram in their original sets. The emoji was added to the cross-platform Emoji 1.0 keyboard in 2015.

• •The first traffic light exploded a few months after installation in London in 1869, seriously injuring the policeman operating it. The idea was shelved for 45 years.
• •The first electric traffic signal was installed on August 5, 1914 at the corner of 105th Street and Euclid Avenue in Cleveland, Ohio.
• •The yellow middle light wasn't part of the original two-color design. Detroit police officer William Potts added it in 1920.
• •In Japan the 'go' light is legally described as 青 (ao, blue), not green. A 1973 government order mandated the bluest possible shade of green so the linguistic convention and international traffic rules could coexist.
• •Project management uses 'RAG' (Red-Amber-Green) status reporting as direct shorthand for traffic-light logic. 🚦 is a common emoji in corporate status reports.
• •Google Trends shows 'red flag emoji' searches outscored 'traffic light emoji' searches by roughly 20 to 1 across 2022–2025. The newer flag metaphor completely overtook the older traffic-light one.
• •Most vendors render all three lights lit at the same time. This is physically impossible on a real signal, but it's the only way to convey 'traffic light' in a small pictogram.
• •Vertical orientation is the default for color-blind drivers. Red on top, green on bottom is a position-based cue that works even without color.

• •Squid Game, Red Light, Green Light (2021): Netflix's giant killer-doll scene turned the children's game and its traffic-light logic into global shorthand. 🚦 caption volume jumped for months after the episode dropped.
• •The Clash, 'Red Angel Dragnet' (1982): punk-era traffic-light imagery, part of a broader tradition of UK rock bands using signal metaphors for societal stop-and-go.
• •F1 race-start lights: five red lights go out, and the race begins. The opposite of a street signal, but the same three-color vocabulary. 🚦🏁 is race Twitter shorthand for 'lights out.'
• •RAG dashboards in enterprise software: from SAP to Jira to Asana, red-amber-green status indicators show up everywhere. 🚦 is the unofficial emoji version.
• •Red Light, Green Light (the children's playground game itself): predates Squid Game by a century. Still taught to kindergarteners in North America. The emoji is the iconic prop.
