If you're looking for insurance, and you happen to be in school, you're going to have an easier time finding lower rates no matter what your age is, compared to not being in school.
First of all, figure out if you can get your insurance off of your parents under any circumstance.
Any age that has the ability to drive can ride off of their immediate parents' insurance policy.
This is preferable, as the alternative is quite a lot more expensive.
But, if you cannot convince them to do so, or for some reason it is not possible to get on a parents insurance you're over 18 and attending school, then your alternative would be student auto insurance.
Student auto insurance is something that applies to anyone in school.
There are a couple ways it can go.
If two people turn 18, and one goes to college, but the other doesn't, then the college kid will be able to apply for "student insurance".
This is basically the same thing as regular, but costs less because of your educational status.
It's also an ideal thing to do if you are an older individual and you decide to go back to school.
If you've been on a normal insurance policy up until 40, you decide to go back to school, and you want to reduce your expenses, then it's suggested that you get "student insurance".
Overall, student auto insurance costs less than regular insurance.
There is also the benefit of taking extra classes (examples would be defensive driving and off road driving) in order to further decrease insurance.
Even at the age of 40 this would apply.
If you've been driving for 20 years, go back to college, and take these classes that you've never taken before, your insurance would drop even FURTHER.
