Dreams involving family members, particularly parents, can often reflect your feelings about authority, safety, and responsibility. In this case, your father's actions may symbolize a sense of recklessness or a fear of losing control in a situation. The lorry driver could represent someone in your life who is affected by your father's choices or actions, suggesting feelings of concern for others around you.

This dream might also indicate your worries about your father's well-being or his decision-making skills. Alternatively, it could reflect your own fears about being unable to protect those you care about or the consequences of actions taken without regard for safety.

Consider how you feel about the situation in your waking life. Are there decisions being made by family members that you disagree with? Are you feeling a lack of control in certain aspects of your life? Reflecting on these questions may help you gain further insight into the dream's meaning.
