Route 7 was a highway in California. It was known for its traffic patterns that would allow for detection, such as determining if one is followed. During Day 6, Masheer Abu-Marzuq was headed towards Route 7, and Jack Bauer realized they would not be able to track him. Jack then crashed into Masheer's car to allow Hamri Al-Assad to offer the man a lift, thereby allowing CTU to track him to Newhall. ("Day 6: 8:00am-9:00am")
