Final answer:
Intermediate license holders under 18 typically cannot drive unsupervised during late evening and overnight hours, commonly from 9 or 10 PM until 5 or 6 AM, to help reduce accident risks.
Step-by-step explanation:
The rules regarding the hours in which an intermediate license holder under age 18 may not drive can vary by state or country, but there are common restrictions. Typically, intermediate license holders are not allowed to drive unsupervised during late evening and overnight hours, often starting from 9 or 10 PM, and ending around 5 or 6 AM the next morning.
These restrictions are meant to reduce the risk of accidents by preventing inexperienced drivers from driving during times when it is more challenging to drive due to limited visibility and a higher likelihood of encountering impaired drivers. Some exceptions often apply, such as driving to and from work or school events.
