All these adjectives are used to criticize actions or people for a lack of proper caution.Rash suggests an overhasty judgement that one might regret ( now isn't the time for us to make rash statements | he would be rash to expect everyone to obey him all the time).Reckless typically describes something more serious: a reckless act is that of a person who simply does not care what damage they cause to themselves or others ( reckless consumption of the earth's resources | he could be convicted of causing death by reckless driving).Foolhardy, as the word suggests, refers to foolish daring, and a foolhardy act is most likely to harm the foolhardy person themselves ( old mines were not to be left open as an invitation to any foolhardy visitor).
