You'll want to do a little bit of preparation before your first driving lesson.
Make sure you chosen a good instructor. Ask around to see if anyone can recommend you an instructor who has helped them in the past. You'll also want to have a think about the types of things you want to work on. Are you brand new to driving and need to start with the basics? Or are you just brushing up on your skills before the test?
Knowing this will help you make the most out of your session.
