How to Use the “100-Mile Rule” to Save 30%
In 2026, the cost of insuring a college-aged driver remains one of the highest expenses for US households, with monthly premiums for students averaging $250 to $450. However, if your student is heading to campus without a car, you could be eligible for a major “hidden” discount.

The 100-Mile Threshold Most major insurers, including GEICO, USAA, and State Farm, offer a “Student Away at School” discount. To qualify in 2026, the requirements are usually:
- The student must reside at a school at least 100 miles away from the primary home.
- The student must not have a vehicle at school with them.
- The student must remain a dependent on the parent’s policy.
Why it Works: This discount can slash the student’s portion of the premium by 15% to 30%. The insurer recognizes that the student will only be driving during holidays and summer breaks, significantly lowering the risk of an accident. When combined with a “Good Student” discount (usually for a 3.0+ GPA), the total savings can exceed $1,000 per year.
