Images of vehicles and methods of transport often represent either our physical body or our personality.
If we are driving, we perhaps feel more in control of our own destiny.
If a passenger, we feel others are trying to control our life.
If we are with friends we may be aware of a group goal whereas if we do not know the other people we may need to explore our ability to make social relationships. Heavy traffic symbolizes external pressure and stress.
Traffic accidents and offences can arise in dreams when we have perhaps not been paying sufficient attention to detail. We have offended a code of conduct that is important for our own safety. Consult the entries for accident and passenger for additional clarification.
