Toggle Traffic Lights

[Patch 1.7.0/Mass Transit] As with the patch 1.7.0[] toggling of traffic lights is now directly included in C:S. There's no need for this mod any more.

Tool to remove or add traffic lights at intersection. Traffic lights can be added and removed at any kind of road intersection including highways and their off- and on-ramps.

A more detailed description can be found on GitHub:

Enable via:
- Button in roads menu.
- Ctrl+T. Behaves like clicking button roads menu.
- Ctrl+Shift+T. Enables the tool everywhere without opening the roads menu. Disable the tool using the same shortcut. The previously used tool gets reenabled then.

Move your mouse of an intersection will show you the existence of traffic lights. Left Click toggles the Traffic Lights. Right Click resets them to their original state.

In version 0.4.0 batch commands (add/remove/reset all traffic lights) were introduced. These commands can be accessed via a right click on the Toggle Traffic Light button in the road menu. Please note: The clicked command gets execute right after the button was clicked -- there is no going back. For additional notes see the release notes:

In version 0.7.0 toggling of lights in tunnels (Cities:Skylines v. 1.10) are possible. Go underground via PageDown, go up again via PageUp, or use PageUp+PageDown if you want to toggle lights above and below the ground on the same time. Details and quirks:

Change Notes: and
Please report issues (and suggestions) on

"Does this actually change traffic, or is it just cosmetic?" - It actually changes the traffic: The cars respect created traffic lights and when traffic lights are removed the cars try to drive through every gap they find (and they are very good at finding the gap...looks kind of funny for intersections with a lot of traffic)
"Does TTL work with tunnels (introduced in Cities:Skylines v. 1.10)?" - TTL does work with C:S v. 1.10. Toggling of Traffic Lights underground were introduced with TTL v. 0.7.0
"Dies TTL work with the addon 'After Dark' (C:S v. 1.2.0)?" - TTL does work with After Dark.

If I disable this mod, will all my intersections be reverted to normal?

Thx for "Remove All TL" option!

Agree with other posters - nice that CO added the functionality to the game, but having to do it intersection by intersection is, at best, tedious. Two-click solution FTW. Thanks for this gem... it makes traffic much more managable, for some reason.

Thank you for making such a great little mod and showing CO the need for it to be integrated into vanilla!

I am wondering if this mod still works because even tho it is in game I would like to keep this for time sack plus the less clicks needed to turn traffic lights off.
