A digital sign with a number and a green line drawn through a white circle confuses drivers.
What does the traffic sign mean?
Again and again drivers encounter new or unfamiliar signs on the road.
Just recently, for example, the green arrow for cyclists was introduced.
Others, on the other hand, have been around for a while but are rather rare, which is why drivers often do not know what they mean – such as the traffic sign with the red dot or an orange arrow on the motorway.
A digital traffic sign with a green wave is definitely new -
explains what it's all about.
Digital road sign with green line and white number - that's what it means
A green line can be seen on the digital traffic sign, which runs once through a white circle.
Some signs also only show a green wave without a circle - but mean the same thing.
There is always a number in white in a square on the digital display - the number itself may vary from sign to sign.
What does the sign mean?
The green wave is actually supposed to represent a "green wave" in a figurative sense.
The number in the box above shows drivers at which speed they have a "green wave" and thus represents a recommendation for how fast they should drive.
It is therefore a speed recommendation.

If you drive at the displayed speed, you will get through the traffic in the best possible way and catch the next traffic light in the green phase.
This avoids constant stopping by red.
The digital sign has been in place in Dresden since 2020 - it has recently also been found in Heidelberg.
Traffic sign indicates speed for "green wave" - that's why the digital sign is sometimes off
The advantage of the digital shield: It can be switched on and off automatically as required.
It is therefore quite possible that some motorists have not even noticed the sign, even if it has already been put up on the side of the road.
Because: If drivers have to stop anyway due to the traffic situation - for example if the traffic light changes to red earlier because a passer-by has pressed the pedestrian traffic light - the digital display goes black.
If the traffic light is already red, it is not worth accelerating for drivers - since the "green wave" cannot be caught at all.
"Green wave" sign for drivers is also available as an analogue sign on the road
A sign with the same meaning, but clearer and not digital, has been around for several years.
The "additional sign 1012-34", like the digital traffic sign, indicates the speed at which drivers can get through traffic easily, explains the "Federal Highway Research Institute" (BASt).
"Green wave at ... km/h" is written on the metal sign.
But there are not only new signs for motorists every year.
There are also some changes this year.
reports which new rules will apply to drivers in 2023.
There will also be a change to driving licenses in 2023 that will affect all drivers.
