Question 1 of 12

According to the safety regulations, all visitors ___ wear a hard hat on site.

Shaky on the rule?

Guessing gets you through a quiz; understanding gets you through the exam. Read the full Must vs have to lesson — 'Must' and 'have to' both express obligation, but their source differs: 'must' usually comes from the speaker's own authority or feeling ('I must call my mother'), while 'have to' points to an outside rule ('I have to wear a uniform'). The real trap is negative: 'mustn't' means forbidden, but 'don't have to' means simply not necessary.
