A person who consumes a good without paying for it is known as a free rider.
The free-rider problem is a type of market failure which occurs when those who benefit from resources, public goods such as public roads or hospitals, or services of a communal nature do not pay for them or pay less.
Free riders are a problem because while not paying for the good either directly through fees or different tolls or indirectly through taxes, they may continue to access or consume it.
