Im pretty sure that you need a concield weapons permit for having the gun beside you in your vehical but other wise you can have it in you trunk or what ever for going out hunting,anyways if you where to have the fire arm beside you or in a place of reach you would have have to have the clip in a place where it is unreachable for instance in the trunk.

It is actually a bit sketchy. According to the law, "It is unlawful for a person to possess a handgun on or about his person, in a vehicle occupied by him, or otherwise readily available for use with a purpose to employ it as a weapon against a person. "

Shortened, it is illegal to have a handgun at your side in a vehicle without a permit to carry, unless it is cased and unloaded.

There is one other line in the law that bears interpretation: "It is a defense that at the time of the act: The person is carrying a weapon when upon a journey." A journey is defined as traveling beyond your circle of neighbors and general acquaintances our outside a person’s normal travel routine.(1)
That is a bit of a challenge, in that there is no clearly defined time when you can carry and each person(judge, juror) will hear something different.

Best practice is to put it in a case, unloaded, separate from ammunition, in the trunk of the car. If it's a truck, the back seat is the best you can do, but make sure you have a lock on the case or trigger.

If you need quick access to the firearm and need to keep a loaded gun in the car, get a permit. It will save you a lot of hassle.

These last 2 are my recommendations in an effort to help you avoid proving a point in court, where you may or may not win. I generally will let someone else spend their money on attorneys fees to get more clear laws.
