The U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) announced a new policy concerning vehicle automation, including its plans for research on related safety issues and recommendations for states related to the testing, licensing and regulation of "autonomous" or "self-driving" vehicles.
Self-driving vehicles are those in which operation of the vehicle occurs without direct driver input to control the steering, acceleration, and braking and are designed so that the driver is not expected to constantly monitor the roadway while operating in self-driving mode.
"Whether we're talking about automated features in cars today or fully automated vehicles of the future, our top priority is to ensure these vehicles – and their occupants – are safe," said Secretary Ray LaHood. "Our research covers all levels of automation, including advances like automatic braking that may save lives in the near term, while the recommendations to states help them better oversee self-driving vehicle development, which holds promising long-term safety benefits."
NHTSA's policy addresses:
- An explanation of the many areas of vehicle innovation and types of automation that offer significant potential for enormous reductions in highway crashes and deaths;
- A summary of the research NHTSA has planned or has begun to help ensure that all safety issues related to vehicle automation are explored and addressed; and
- Recommendations to states that have authorized operation of self-driving vehicles, for test purposes, on how best to ensure safe operation as these new concepts are being tested on highways.
Several states, including Nevada, California and Florida have enacted legislation that expressly permits operation of self-driving (sometimes called "autonomous") vehicles under certain conditions. These experimental vehicles are at the highest end of a wide range of automation that begins with some safety features already in vehicles, such as electronic stability control.
The DOT's policy will provide states interested in passing similar laws with assistance to ensure that their legislation does not inadvertently impact current vehicle technology and that the testing of self-driving vehicles is conducted safely.
"We're encouraged by the new automated vehicle technologies being developed and implemented today, but want to ensure that motor vehicle safety is considered in the development of these advances," said NHTSA Administrator David Strickland. "As additional states consider similar legislation, our recommendations provide lawmakers with the tools they need to encourage the safe development and implementation of automated vehicle technology."
The policy statement also describes NHTSA's research efforts related to autonomous vehicles. While the technology remains in early stages, NHTSA is conducting research on self-driving vehicles so that the agency has the tools to establish standards for these vehicles, should the vehicles become commercially available. The first phase of this research is expected to be completed within the next four years.
NHTSA's many years of research on vehicle automation have already led to regulatory and other policy developments. The agency's work on electronic stability control (ESC), for example, led to a standard mandating that form of automated technology on all new light vehicles since MY 2011. More recently, NHTSA issued a proposal that would require ESC on new heavy vehicles.
