Not knowing where you’re from Luke or anything about you other than your male, 16 or going to be 16 and driving soon. I have no idea if you’re working or in school, what kind of budget you have or what the laws are regarding fixed blade knives in a vehicle and where that blade might be in proximity to a minor.
Not knowing any of that about you, which btw when posting a question like you did is crucial in order to give you any kind of realistic and accurate answer.
I would highly suggest you fill out your profile because without you telling us in you original post anything about yourself, the first place anyone inclined to help you looks is going to be your profile. You want to make answering your question as a easy as possible and the best way to do that is to make your intent as clear as possible. Don’t make the reader fill in the blanks because 9 out of 10 times we’ll fill in the opposite of what it is.
I see you’re a new member also, did you introduce yourself in the introduction thread
“We were all new here once.”on the top page of General?
Having said all that in my long winded way I’ll give you the only responses I can based on what I know about you.
1) With you being a minor I wouldn’t recommend riding around with a knife in car/ truck without knowing local laws with regard to being a minor and having a knife in public and then having it in the car/truck without an adult present. Also find out if there are restrictions on blade shape or length.
B) Figure out why you want to have a knife in your vehicle. What purposes do you foresee the blade being used for? Bivouacing? BOB? Just to have in back for whatever might arise? Those along with the environment and finances will most likely get you an answer and one that just might help.
Finally consider carefully keeping a large knife in a vehicle and how you’ll secure it. As an esteemed member and person’s opinion I’ve always respected pointed out to me a long time ago. Any large knife not securely fastened/stored in a vehicle anywhere, quickly becomes a dangerous, sometimes deadly projectile in the course of an automobiles accident as it’s ripped from its moorings and begins flying around the interior of the vehicle.
If you’re allowed, a Leatherman style multi tool on a belt sheath will always serve you better in almost any emergency situation you’ll encounter.
I have a Leatherman Supertool 200 I often have on my belt and I keep a custom Koster bushcraft knife rigged with everything I’d need to survive a few days in an emergency secured in a tool bag I use for an emergency bag.
