Which of the following restrictions could be applied to a driver with a learner's permit?

All of the restrictions mentioned are commonly applied to drivers with a learner's permit, ensuring that novice drivers gain experience in safe conditions.

Having a prohibition on nighttime driving helps to reduce the risk associated with less experienced drivers operating a vehicle in low-light conditions, where visibility is limited and reactions may need to be quicker.

Limiting driving on highways is also a safety measure, as highways often involve higher speeds and more complex driving situations that could be overwhelming for someone still learning the fundamentals of driving.

Requiring that the learner be accompanied by a qualified adult ensures that there is supervision available, providing guidance and a safety net in case of mistakes. This adult typically holds a valid driver's license and can help the learner navigate challenging driving situations.

Collectively, these restrictions aim to provide a comprehensive approach to training, allowing the learner to build confidence and competence behind the wheel while minimizing risks.
