What are modal auxilairies and their use-

• A modal auxiliary is a type of verb that indicates a certain modality such as likelihood, ability, suggestion, order, or request.
• Some common examples of auxiliaries are could, can, may, should, must, would, etc.
• It is used as a helping verb in sentences where the main verb is also included in the sentence.
• Each modal auxiliary indicates different use and form when used in sentences.
• When we talk about the modal auxiliary 'should', it is used to make recommendations or give advice. It implies a certain obligation.
• The auxiliary 'must' has a lot of indications, but it mainly expresses a necessity or an insistent demand.
• As we look at the sentence it is a suggestion and also a necessity to drive carefully. So either 'should' or 'must' can be used in the blank.
