Signal controlled junctions
We may see traffic light-controlled junctions at any junction type, a T junction, a crossroad, a roundabout, sometimes on slip road or even temporary signals at roadworks.
A great way to treat traffic light controlled junction is just imagine they are the same as any junction, the only difference being that the traffic lights control the stop line painted on the floor.
Just because we see a green light doesn’t mean it is safe to cross oncoming traffic!
Sequences aside, generally if we see a red light, we must stop at the line. When it is green, we can cross the line. We must then give way to other traffic the way we normally would.
We have already mentioned that some junctions may have an area for cyclists and/or a pedestrian crossing.
We must not stop on or block these areas, always make sure you can clear the junction fully before moving forward.
It can be dangerous to block either of these as it can cause pedestrians to walk around and be close to cars and it
restricts all road users views all around. Because of the danger stopping on these areas can cause, stopping on them on these during a driving test, it will be treated as a serious fault.
If we are driving towards a green light, we should adjust our speed so we can come to a safe stop if the light changes to red.
There is a "point of no return" where suddenly stopping would not be a safe option, this is why we have an amber phase where we should only stop if it is safe to do so.
We should never speed up to "catch a green light", every junction is a potential accident blackspot and should be approached with caution.
