Study guide
Connect this sign to practice
Length limit (10 metres) is a "don't", and the Thai exam likes to probe the until-when part: where the prohibition lifts, what overrides it, and whether common driver workarounds are still legal. Practising it in context makes the answer obvious.
Now see it in questions.
Spotting Length limit (10 metres) 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.
