  Vehicular Ad Hoc Networks (VANETs) play a crucial role in enhancing road
safety and traffic efficiency by enabling communication between vehicles (V2V)
and between vehicles and infrastructure (V2I). Robust trust management is
necessary to ensure the reliability of information in decentralized systems.
This paper presents the notion of a ``Trust Field" in VANETs, conceptualized as
the behavior of the nodes that represents trust levels evolving in both spatial
and temporal dimensions. Using the LogitTrust model, we provide empirical
evidence of how trust fields in vehicular networks change over time in
different scenarios, including when malicious nodes are present. The results of
our study demonstrate that the trust domain can adjust to fluctuations in
network conditions, thereby offering a comprehensive metric for assessing the
reliability of nodes. This innovative method improves the dependability of
VANET applications by efficiently detecting and mitigating malicious actions.
