Dreams involving vehicles often symbolize your journey in life, control, and direction. In your dream, being run off the road by an 11-year-old boy driving his parents' car may signify feelings of vulnerability or a lack of control over your circumstances. The boy could represent innocence or a sense of immaturity in a situation that feels serious or out of your hands.

The need for a special seat belt that only arrives after the crash suggests that you might be feeling unprepared or lacking the necessary protection or support in a current situation. This could relate to a personal challenge or a feeling of being overwhelmed by external factors.

Consider reflecting on areas in your life where you feel out of control or where you might need additional support. It may be beneficial to seek assistance or guidance in these areas to help you feel more secure as you navigate your path.
