The vehicle involved in the incident is believed to have been located abandoned in the Beit Lid area.
Police are still seeking the suspected attacker, with local officers conducting searches along nearby roads and in open areas.
Ground teams are being supported by security forces, police helicopters, search dogs and Yasam motorcycle units.
Daniel Levi, commissioner of the Israel Police, is reportedly en route to the scene to conduct a "situational assessment”.
The ramming follows a similar attack in the northern Israeli town of Pardes Hanna-Karkur, which injured 12 people in February.
The suspect in that case, identified as a 53-year-old Palestinian from the Jenin, was killed by police shortly after the incident.
