Do you want information about driving licenses from other states and foreigners?
Yes
You can drive in New York State with a valid driver's license from another state or country. You do not need to apply for a New York State driver's license unless you become a New York State resident.
I also need more for about New York. Thanks! What should I practice for my exam?
You should be practicing "everything": steering, acceleration, braking, speed, clutch... etc. But if you ask what are the most important things, I can tell you Steering, and Acceleration.Make sure to steer smoothly whether you are driving straight ahead, turning or backing up, and moderate and smoothly acceleration are key!
If I want to change my license from one class to another (in the near future), would I need a Pre-Licensing Course certificate?
No. You don't need a PLCC, as long as you have a valid NY state driver license you can apply to change your class.
One more question, you said before that accelerating smoothly and moderately was key, but what if I have to drive on a highway in my test? I can't go moderately, since all the vehicles will be honking since I'm going slow.
