Recently, Sutradhar (2024) proposed a quantum cryptographic protocol for secure vehicular communication. The author claimed that the proposed protocol is unconditionally secure and can resist various well-known security attacks of outsiders or participants. However, in this comment article, we demonstrate that the proposed protocol is vulnerable to an entangle-measure attack by a dishonest participant and an outsider, and a collusion attack by dishonest participants. In addition, theoretically it cannot guarantee the unconditional security because the hash function is not a perfect one-way function.
