Florida Highway Signs Go Viral for Their Hilarious — and Effective — Safety Messages
MIAMI, FLORIDA — Commuters across South Florida are getting more than just traffic updates on their daily drives — they’re getting laughs.
A series of clever electronic highway signs in Miami-Dade County has gone viral for their witty — and sometimes hilarious — safety reminders, with phrases like “Your Mummy Says Slow Down” and “Ghosting Is Cool, Put the Phone Away.”
The posts, shared by Only In Dade, show a mix of humor and public safety that’s quickly winning over drivers and social media users alike.
The Signs That Caught Everyone’s Attention
The now-viral photos showcase some of the standout messages:
- “Your Mummy Says Slow Down” — a spooky-season reminder for speeders.
- “Ghosting Is Cool. Put the Phone Away.” — a tongue-in-cheek warning about distracted driving.
- “Only Sparklers Should Be Lit. High = DUI” — a sharp Fourth of July safety slogan.
- “You’re Not a Firework. Don’t Drive Lit.” — another play on words reminding drivers not to drink or use substances before getting behind the wheel.
- “Don’t Drive Star-Spangled Hammered” — a patriotic pun that’s become a fan favorite online.
Each message appears on overhead traffic boards along busy interstates in Miami, where thousands of drivers pass by daily.
Creative Messaging With a Purpose
The Florida Department of Transportation (FDOT) has not confirmed the identity of the witty mind behind the messages, but residents are already calling for them to get a raise.
“Whoever’s in charge of these signs needs a promotion,” one user commented on the viral Only In Dade post, which has racked up thousands of likes and shares.
While the messages draw laughs, officials say humor can be an effective public safety tool, especially when it gets drivers to actually read and remember critical warnings.

Social Media Applauds the Initiative
Across TikTok, X, and Instagram, the campaign has earned praise for being both funny and functional. Drivers say it’s refreshing to see local agencies connect with the public using language that feels modern and relatable.
“I saw the ‘Ghosting Is Cool’ sign on my way to work and literally put my phone down,” one Miami commuter wrote. “Mission accomplished.”
A South Florida Tradition of Humor
This isn’t the first time Miami’s highway boards have gone viral. Similar clever messages have appeared during holidays, severe weather alerts, and even sports events — part of the city’s growing reputation for blending humor with community outreach.
Officials hope the trend continues — because if it keeps drivers laughing and slowing down, it’s doing its job.
