The average cost of a driving lesson is 30-70 dollars a lesson. On more higher end, you are provided with a car that you can test driving around in the city with the instructors.
Between $35-45 per hour depending on location. A driving course completion certificate can help reduce insurance costs by up to 20% for teen and newly-insured drivers.
If you include classroom lesson and behind-the-wheel training (and buy the packaged deal most schools offer), the cost is about $400-$500. In my opinion, it is definitely worth it for the reduction in insurance cost.
