In most places, it is not allowed for a person to thumb a ride from the driver of a private carrier, such as a cab or a truck. This is because the driver is not obligated to provide transportation to anyone who is not a paying customer, and it can be considered as soliciting or unauthorized entry into a vehicle.
Additionally, it can be dangerous to hitchhike, as the driver may not be trustworthy or may be driving under the influence. It is always best to use public transportation or a ride-sharing service to get around, as these services provide a safe and reliable way to travel.
