The Girl Hitchhiking is an unnamed female character in GTA V. She appears in the random event “Hitch Lift 3”.
Sandy Shores, Blaine County, San Andreas
The girl hitchhiking in GTA V remains a bit of a mystery, with limited information about her background. She shares that she recently had a party with friends in Sandy Shores and woke up with no memory of the previous night.
She has a seldom-seen boyfriend who provides her with money, which she quickly spends. She identifies herself as an adventurous, free-spirited individual, using drugs like ecstasy and enjoying the desert.
Her connection with her boyfriend seems primarily financial, as she visits him only when she needs more money, which creates tensions in their relationship.
The Girl Hitchhiking can be encountered at the junction of East Joshua Road and Route 1 in the San Chianski Mountain Range. She requests a ride to Mount Haan Drive in Vinewood Hills to surprise her boyfriend, a security guard at the broadcast tower near the Vinewood Sign.
During the ride, her boyfriend calls, revealing she's borrowed money from him and is with a man. Later, she speaks with her boyfriend, now identified as Brian, about a party in Sandy Shores, trying to hide her relationship with him.
When they reach the destination, Brian confronts the protagonist, leading to a fight. If her boyfriend is knocked out, she accuses the protagonist of being a psychopath and can be left with Brian or killed.
Alternatively, Trevor can take her to the Altruist Cult, leading to a humorous dialogue exchange before reaching the cult's location.
The Girl Hitchhiking is seen wearing a short printed dress and brown boots.
