In my state yes.
In Calif it is allowed also, but not between 11PM and 5AM curfew until 18 and there are some restrictions about passengers underage that I am not sure exactly what
Depends on what state you're in (You never mentioned where you live). In many states though, a 16 year old can obtain a Drivers License and legally drive a car or truck/SUV. What is the specific SUV that you'd want to drive? Just curious...
Yes in New York with certain times...
Check with your local licensing authority as rules can vary significantly from state to state.
