This is a very usual question that I find in a lot of sites and really the answer is no easy as any one would like, the insurance- rates depends on a lot of factors, so not everybody at 17 year old pay the same premium for their insurance.
What I can tell you is that usually at this age the insurance is more expensive than the average, this is because young drivers are considered high risk drivers to insurance companies and this is why they pay more for their insurance.
If this is your case I recommend you to get and compare quotes from as many companies as you can because this is the only way to find the best option for you, but remember that not always the cheapest is the best option, I also consider that is best to get full coverage insurance instead of only liability because this way you are more covered.
Another tip that I can give you is if you can to go under your parents policy, this way you can find better rates, also ask the insurance companies if they have student discounts, usually they gave but you should keep good grades to get it. Also take drivers Ed, this can help also lowering your premium.
