Yes, you need to register any vehicle you own at the DMV.
What do I need to  bring to get it registered?
Complete the DMV's Document Guide to make sure you bring everything you need.
I'd also like to learn more about the passenger class plates. What if I have a modified pick-up that weighs less than 5 pounds empty?
In that case you may register it in the passenger class if it meets our conditions.
Should I renew my registration, can I change the class of the vehicle at the same time?
Does your registration expire in less than 60 days?
No, it will take longer than that.
Unfortunately, no relevant information is found.
Say, what if I use the pick-up without the needed modifications?
