HOW TO HACK ROAD SIGN
-
The access panel on the sign is generally protected by a small lock, but often are left unprotected.
-
If there is padlock, use a shim to open, you could also use bolt cutter but don't recommend it. Do not replace the padlock (if have one), DOT crews would have no idea what happened. It's good you are doing praxis, but you shouldn't cause extra trouble for fellow workers to deal with
-
Upon opening the access panel you can see the display electronics
-
The black control pad is attached by a curly cord, with a keyboard on the face
-
Programming is as simple as scrolling down the menu selection to “Instant Text”. Type whatever you want to display, Hit Enter to submit. You can now either throw it up on the sign by selecting “Run w/out save” or you can add more pages to it by selecting “Add page”
-
Should it ask you for a password. Try “DOTS”, the default password.
-
also State DOT sometime will sometimes name the password after the state code, for example Washington will have WSDOT and Virginia with VADOT.
-
In all likelihood, the crew will not have changed the password. However if they did, never fear. Hold “Control” and “Shift” and while holding, enter “DIPY”. This will reset the sign and reset the password to “DOTS” in the process. You’re in!
