Connect this sign to practice
Prohibition signs like Speed limit (80 km/h) carry instant fines on the road and trick wording on the exam. Questions test where the rule starts, where it ends, and which adjacent signs cancel it. Practising it in the question flow keeps those edges fresh.
Now see it in questions.
Spotting Speed limit (80 km/h) in isolation is one thing. Recognising it inside a real exam-style question, among lookalikes and trick wording, is another. The diagnostic mixes it in for you.
