One of the safest ways to work with your teen to become a better driver is to stage the behind the wheel driving exercises in increasingly complex and varied environments as they show confidence and competence. And you should do so in increasing order of risk. So here's the order. Start with parking lots. Low risk, low stress environment. There they can practice driving in reverse, turns, mirror use and parking. When they're comfortable there, move to residential streets where they get some experience maneuvering their car with cars on their right and traffic on the left, and they improve their visual scanning skills looking for kids and dogs and bikes, the kind of things you encounter on residential streets. When you're comfortable there, move to country roads where the speeds are higher and the challenges are a little bit different. On country roads, practice passing where you have long straightaways, and also practice proper braking so that you are losing all of your speed doing all your braking on the straightaways, coasting through the curves and then accelerating out of the curves. When you're comfortable in that situation, then move to high speed freeways where you can practice merging traffic and lane changing and sharing the road with trucks and lots of other traffic at high speed. And finally when you're comfortable on that environment, move to the most difficult for beginning drivers environment of all - busy urban environments where there's more action and distractions and traffic and noise. Now, car crashes involving personal injury and damage happen at twice the rate in urban environments compared to rural environments. But the fatality rate is half that, primarily because the speeds are lower. These practice sessions should all begin in daylight, in a good weather. Once your teen is comfortable and you feel comfortable in all those environments, then go back to them again in that same order in more hazardous conditions - at night, in a bad weather like fog, sleet and snow.
