Which action is part of maintaining compliance with DOT standards?

Maintaining compliance with DOT (Department of Transportation) standards is essential for ensuring the safety of drivers, vehicles, and road users. The action of adhering to driving hour limitations directly aligns with these standards, which are designed to prevent driver fatigue and promote safe driving practices. The DOT establishes specific regulations on how many hours a commercial driver can operate a vehicle within a given timeframe, along with mandatory rest periods. Following these regulations helps to reduce the risk of accidents caused by tiredness and improves overall roadway safety.

While maximizing load capacity, increasing driver downtime, and adjusting payment structures may be relevant factors in logistics and operations, they do not directly address the regulatory requirements laid out by the DOT. The focus on driving hour limitations specifically highlights the importance of compliance with safety regulations, making it the most appropriate answer in this context.
