The short answer
In most families, the cheapest and simplest answer is to keep the student on the parents policy, and tell the insurer the student is away at school. If the student leaves the car at home and goes to school more than 100 miles away, that usually unlocks a student away discount. If the student takes a car to campus, update the garaging address to the school ZIP code and keep them on the family policy. A separate policy in the student’s own name is usually the most expensive option, and removing or excluding the student is the riskiest option, because it can leave them with no cover when they drive at home during breaks.
The decision turns on one fact: where is the car, and who drives it?

The three-way choice, in one table
Every family with a college student faces the same three options. They differ in cost, in cover during breaks, and in what happens if the student crashes a family car.
| Option | How it works | Usually cheapest? | Cover during school breaks | Main risk |
|---|---|---|---|---|
| Keep on the parents policy | Student stays listed as a driver on the family policy, with the garaging address updated | Yes, in most families | Yes, they are covered when home | None, if the insurer is told the truth about where the car is |
| Own policy in the student’s name | Student buys a separate policy, often for a car titled in their name | No, usually the most expensive | Yes, if the policy stays active | Young driver with no multi-car or multi-policy discounts pays full price |
| Exclude or remove the student | Student is formally excluded, or taken off the policy entirely | Lowest premium on paper | No, an excluded driver has no cover in a family car | A crash during a break can mean no cover and a denied claim |
Discounts matter, but they are the second question. The first question is which of these three structures fits where the student actually lives and drives.
Option 1: keep them on your policy
This is the default for most families, and it is usually the cheapest because the student benefits from the family’s multi-car discount, the parents’ driving history, and the household’s tenure with the carrier. Insurance.com notes that keeping a student on a parent’s policy is often cheaper than a separate policy.
Keeping them on the policy does not mean leaving it untouched. Tell the insurer the student is away at school, and say whether the car goes with them. If the car stays home and the student is more than 100 miles away, ask about the student away discount. If the car goes to campus, update the garaging address to the school ZIP code, because the garaging location, not the student’s claimed residency, is what sets the rate. Also update the student’s driver status: a student away without a car is an occasional driver, not a primary driver on a family car, and that reclassification is part of why the premium falls.
The two discounts that do the work
Two discounts show up in almost every college guide, and both can apply at once, though each one applies to the premium that remains after the other, so they do not simply add together.
The good student discount rewards grades. Insurance.com reports that it averages 12 percent, for students with a B average (a 3.0 grade point average) or better, or in the top 20 percent of the class, and that it usually applies to full-time students age 25 and under. CarInsurance.com reports a similar average of about 12.5 percent. Carrier examples vary: Insurance.com lists Nationwide at 17 percent, State Farm at 15 percent, Allstate at 11 percent, and GEICO at 8 percent. Proof is usually a transcript or a dean’s list letter, and most carriers ask you to re-verify it every term.
The student away discount rewards distance. Insurance.com reports that it averages 11 percent, and runs as high as 25 percent at State Farm. Its separate college comparison lists GEICO at 19 percent and State Farm at 26 percent, which shows how much the figure moves by carrier. The usual conditions are full-time enrollment, school more than 100 miles from home, and no car at school.
A worked example shows how these discounts move a real bill. Use round numbers, not a quote. Suppose the student’s share of the family premium is $2,400 a year before discounts.
| Step | Math | Result |
|---|---|---|
| Student’s share before discounts | $2,400 | |
| Good student discount, 12 percent | $2,400 x 0.12 | $288 off, premium now $2,112 |
| Student away discount, 11 percent on what remains | $2,112 x 0.11 | $232 off, premium now $1,880 |
| Total saving | $2,400 minus $1,880 | $520 a year |
That $520 is an illustration, not a promise. The real saving depends on the carrier, the state, and the student’s share of the premium. But the shape of the answer is stable: the two discounts together can cut the student’s share by roughly a fifth, and they cost nothing except a phone call and a transcript.
Option 3: exclude or remove the student, and why it is risky
Removing a student from the policy sounds like free money, because the premium falls. The problem is what happens next. An excluded driver is someone the policyholder and the insurer have formally agreed will not be covered under the policy, usually in a signed endorsement. If an excluded driver causes an accident in a family car, the insurer will not pay for the other driver’s injuries, for property damage, or for damage to the family car. That is a total gap, not a reduced payout.
A student who is simply removed, rather than formally excluded, faces a similar risk. When the student comes home for a break, they will drive. If they crash a family car and the insurer finds they are a resident household member who was not disclosed, the claim can be denied, or the policy can be cancelled. CarInsurance.com warns against excluding a student for the same reason. Removal fits only when the student has moved out permanently, has their own policy and their own car, and will not drive a family car again.
The decision path: answer four questions
Question 1: Does the student take a car to school? If no, keep them on the parents policy and ask for the student away discount. If yes, go to question 2.
Question 2: Is the school more than 100 miles from home? If the car stays home and the school is more than 100 miles away, the student away discount usually applies. If the school is closer, the discount usually does not, but the student is still an occasional driver, so tell the insurer and ask what that changes.
Question 3: Is the car titled in the student’s name, and does the student live away year-round? If yes to both, price a standalone policy and compare it with the family policy. If no, stay on the family policy.
Question 4: Will the student drive a family car during breaks? If yes, and the answer is yes for almost every student, do not exclude them. Keep them listed, so break driving is covered.
| Situation | Best starting option |
|---|---|
| No car at school, school 100-plus miles away | Keep on parents policy, claim student away and good student discounts |
| No car at school, school under 100 miles away | Keep on parents policy, update to occasional driver, claim good student discount |
| Car at school, car titled to parents | Keep on parents policy, update garaging address to school ZIP code |
| Car at school, car titled to student, lives away year-round | Price both, compare standalone policy with family policy |
| Student moved out permanently, own car and own policy | Removal may fit, confirm in writing with the insurer |
The out-of-state registration clock
If the student takes a car to school in another state, a second clock starts. Most states require a car garaged in the state for more than a set period to be registered there, and to carry insurance that meets that state’s minimums. BestMoney reports the commonly cited range as 30 to 90 days.
That range is not a single national rule. Each state sets its own deadline, and some states exempt full-time students while others do not. Before move-in, check the motor vehicle department in the school state, and ask the insurer whether the current policy meets that state’s minimum liability requirements. A policy that is legal at home can be short of the minimums in the school state, and the gap only matters after a crash. The same check applies to the driver’s license: some states require a new license after the same residency period, and some exempt students.
Cover during school breaks, and the summer problem
The student away discount applies during school terms, not during summer breaks, according to BestMoney. When the student comes home for the summer and starts driving daily again, the discount typically ends, and the premium goes back up. That is normal, and it is not a reason to hide the change from the insurer. The practical rule is simple: the policy should match where the student actually is. At the start of each term, tell the insurer the student is away. When the student comes home for a long break, tell the insurer they are home and driving.
A car left on campus while the student is home still needs cover. Comprehensive coverage protects it against theft, vandalism, and weather while it sits. Do not drop comprehensive on a car parked on campus for a month to save a small premium, unless you can afford to replace the car yourself.
