My daughter was a very confident driver, passed her test first time, but the first time she went out in her car with her mates, all laughing and shouting at each other, she totally lost her nerve, pulled over, and refused to drive any further. All her friends had to call home and get parents to collect them. Has your DD already driven a few times with friends in her car OP? If she's done it on numerous occasions, and still felt confident, then I would say she'll be OK, however, if she's used to pootling around on her own, or with just you in the car, I wouldn't be at all keen on letting her do it either.
Some people are pointing out that accidents are far fewer on motorways, but what they're not acknowledging, is that they're usually far more serious due to the speeds being travelled.
Is your DD the type who is able to have a serious conversation with, and will listen to you OP, or is she more a typical teen who thinks she knows it all, and you know nothing? If it's the first, then I'd sit her down, and have a serious conversation with her, explaining, that while you know she's a good driver, you're worried about her driving all the way there and back, when she's VERY inexperienced. Then show her this:
Teenage drivers, particularly those with limited experience, are statistically at a higher risk of crashes on motorways compared to more experienced drivers, due to factors like inexperience and a tendency to take risks.
Here's a more detailed breakdown:
Why Teenage Drivers Are at Higher Risk:
Inexperience:
Young drivers often lack the experience to anticipate and react to hazards, especially at high speeds on motorways.
Hazard Perception:
They may struggle to identify potential dangers and react appropriately, leading to accidents.
Risk-Taking Behaviour:
Teenagers are more prone to risky driving behaviors like speeding, dangerous overtaking, and distractions.
Overconfidence:
New drivers may overestimate their abilities and become overconfident, leading to unsafe driving practices.
Distractions:
Passengers, phones, and other distractions can significantly increase the risk of accidents, especially on motorways where attention is crucial.
If she still won't listen, then I'd be tempted to over rule her in this instance, and simply tell her that she's NOT doing it! I would also speak to your son, and ask him to discourage her from picking them up.
