A Maryland vehicle agency will shut down as it struggles to hire enough employees to handle its $7 billion budget.

The Maryland Vehicle Administration said Tuesday that it will lay off 2,000 employees as part of a sweeping restructuring aimed at reducing costs, while maintaining a robust workforce.

The agency has spent about $100 million a year on the effort, which will result in the elimination of 4,000 jobs.

The department is struggling to keep up with growing traffic, as more and more drivers use private vehicles, which have become more popular.

Maryland is one of the few states to mandate the use of private vehicles for all vehicles in the state, a move that is expected to increase the number of people using them.
