Yes he does. Every driver at some point has to learn to handle weather conditions on the road. If he's got his license then I presume he has at least some experience driving in the dark, the rain, etc. and can probably determine when he needs to just get off the road. My DD17 has been driving for 6 months and I worry about her too. Not because she's a bad driver, but because I'm her mom.
Very true. When our first snowfall hit I took the twins to the school parking lot to practice driving in snow and on slippery roads. DS15 was very timid and wouldn't "try" to skid. DD was like "whoppie, lets go yee haw!!". I do worry about her a LOT
. She had a little too much fun doing donuts in the parking lot. We live in Minnesota, you can't NOT know how to drive in snow.
