Final answer:
The number of passengers a probationary driver license holder can have, excluding dependents, varies by location. It is important to check with the local Department of Motor Vehicles for specific regional regulations.
Step-by-step explanation:
The number of passengers a holder of a probationary driver license is permitted to have in the vehicle, excluding dependents, can vary depending on the specific laws of the state or country in question. Generally, many regions impose restrictions on new drivers to limit the potential distractions and reduce the risk of accidents. These restrictions can include limitations on the number of non-family passengers, especially for young drivers. For example, in some states in the United States, a probationary driver may only be allowed one non-family passenger under the age of 21. However, the exact rules can differ, so it is essential to check the local Department of Motor Vehicles (DMV) or equivalent authority for the specific regulations that apply.
