The Department of Transportation (DOT) and various state agencies exercise broad powers over our business, generally governing such activities as authorization to engage in motor carrier operations, safety and financial reporting. We may also become subject to new or more restrictive regulations imposed by the DOT, the Occupational Safety and Health Administration, the Food and Drug Administration or other authorities relating to engine exhaust emissions, safety performance and measurements, driver hours of service, drug and alcohol testing, food safety, security, ergonomics, as well as other unforeseen matters. Compliance with such regulations could substantially impair equipment productivity and increase our costs.
Taxes are a significant part of our annual expenses, and we are subject to various federal and state income, payroll, property, sales and other taxes. In addition, various federal and state authorities impose significant operating taxes on the transportation industry, including fuel taxes, tolls, excise and other taxes. There can be no assurance that such taxes will not substantially increase or that new or revised forms of operating taxes or tax laws or regulations, will not be imposed on the industry. Higher tax rates, claims, audits, investigations or legal proceedings involving taxing authorities could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.
The FMCSA rules on motor carrier driver hours of service limit the maximum number of hours a driver may be on duty between mandatory off-duty hours. These rules could result in us not meeting customer demands, upward pressure on driver wages and benefits, underutilization of our truck fleet and/or use of higher cost purchased transportation which could have a material adverse effect on our financial condition, results of operations, liquidity and cash flows.
The Company's operations are subject to a variety of other federal, state and local laws and regulations, including labor and employment, wage and hour and employee benefit laws and regulations, tax, environmental, health and safety, data privacy, anti-trust and securities laws and regulations. Compliance with these laws and regulations is onerous and expensive. New and changing laws and regulations can adversely affect the Company's business by increasing costs and requiring changes to the Company's business. New and changing laws and regulations can also create uncertainty about how such laws and regulations will be interpreted and applied. There can be no assurance the Company's employees, contractors or agents will not violate such laws and regulations or the Company's policies and procedures. If the Company is found to have violated laws and regulations, it could materially adversely affect the Company's business, reputation, results of operations and financial condition.
