National Highway Traffic Safety Administration in the context of "Fuel economy in automobiles"

A headlamp is a lamp attached to the front of a vehicle to illuminate the road ahead. Headlamps are also often called headlights, but in the most precise usage, headlamp is the term for the device itself and headlight is the term for the beam of light produced and distributed by the device.

Headlamp performance has steadily improved throughout the automobile age, spurred by the great disparity between daytime and nighttime traffic fatalities: the US National Highway Traffic Safety Administration states that nearly half of all traffic-related fatalities occur in the dark, despite only 25% of traffic travelling during darkness.

Aggressive driving is defined by the National Highway Traffic Safety Administration as the behavior of an individual who "Commits a combination of moving traffic offenses so as to endanger other persons or property." In the context of modern vehicle management, understanding and mitigating aggressive driving is a key component of effective Fleet management.

The United States secretary of transportation is the head of the United States Department of Transportation. The secretary serves as the principal advisor to the president of the United States on all matters relating to transportation. The secretary is a statutory member of the Cabinet of the United States, and is fourteenth in the presidential line of succession.

The secretary of transportation oversees the U.S. Department of Transportation, which has over 55,000 employees and thirteen agencies, including the Federal Aviation Administration, the Federal Highway Administration, the Federal Railroad Administration, and the National Highway Traffic Safety Administration. As of January 2021, the secretary receives an annual salary of $221,400.

Corporate average fuel economy (CAFE) standards are regulations in the United States, first enacted by the United States Congress in 1975, after the 1973–74 Arab Oil Embargo, to improve the average fuel economy of cars and light trucks (trucks, vans and sport utility vehicles) produced for sale in the United States. More recently, efficiency standards were developed and implemented for heavy-duty pickup trucks and commercial medium-duty and heavy-duty vehicles. CAFE neither directly offers incentives for customers to choose fuel efficient vehicles nor directly affects fuel prices. Rather, it attempts to accomplish the goals indirectly, by making it more expensive for automakers to build inefficient vehicles by introducing penalties.

CAFE standards are administered by the secretary of transportation via the National Highway Traffic Safety Administration. The original CAFE standards sought to drive automotive innovation to curtail fuel consumption, and now the aim is also to create domestic jobs and cut global warming.Stringent CAFE standards together with government incentives for fuel efficient vehicles in the United States should accelerate the demand for electric vehicles.
