PYT mod · Transport Fever 3 · free on mod.io
Speed limit signs that read the road -- and change by themselves when you upgrade it. Or pick any sign. km/h or mph, International or US.
Drop it beside any road and it shows that road's real speed limit — and changes by itself when you upgrade the road. km/h, UK mph or the American SPEED LIMIT sign.
PYT - Speed Signs. Pace Your Traffic. A PYT (Play Your Transport) mod by Epod. A sister of PYT - Town Signs and PYT - Distance Signs.
Choose Auto and the sign looks at the road beside it: a 50 km/h street gets a 50, a country road an 80, a motorway a 130. Upgrade the road and every Auto sign along it follows within seconds — no more signs that lie.

Neu in 1.1: Linksverkehr – die Schilder wissen jetzt, auf welcher Straßenseite ihr fahrt.
Germany is PYT's biggest supporter: more of our players come from Germany than from any other country. Since you back us the most, it's only fair you get the brief in German too. Spot some clumsy German? Tell us in the comments!
Danke, Deutschland! Die meisten PYT-Spieler kommen aus Deutschland – ihr seid unsere größten Unterstützer.
Worum es geht: Tempolimit-Schilder, die die Straße lesen: Mit Auto zeigt das Schild das echte Tempolimit der Straße daneben – und wechselt von selbst, wenn ihr die Straße ausbaut. Oder jedes Tempo aus der Liste, oder Kein Limit. km/h oder mph, runde internationale Schilder oder das amerikanische SPEED-LIMIT-Schild. Das Baumenü ist auf Deutsch.
So geht’s:
1.1 — THE LEFT-HAND DRIVERS WIN

Not every sign in the picture comes with this mod — they are three separate PYT mods: PYT - Speed Signs (this mod) · PYT - Distance Signs · PYT - Town Signs — or get all three at once: PYT - Complete Road Signs Collection
OK, the left-hand drivers win — even if I am one, being in Australia. Every sign now knows which side of the road you drive on.
★ Thank you, NovaOfZion and jimbo_1977! You asked for left-hand driving — here it is.
