Final answer:
A student with an instruction permit must drive with a qualified instructor aged 21 or older, and up to three others may accompany if the car has dual controls. This can vary by location, so checking local laws is advised.
Step-by-step explanation:
When holding an instruction permit, a student driver must be accompanied by a qualified instructor who is 21 years of age or older in the front seat. In some jurisdictions, this can also be a licensed parent, guardian, or other adult who meets the age requirement and has a valid driver's license.
The vehicle may be permitted to carry up to three passengers if it is equipped with dual controls. However, it's important to note that the exact rules can vary by state or country, so it's always best to check the specific driver's manual or local driving laws for accurate information.
