Fully autonomous cars & trucks that drive us instead of us driving them will become a reality. These self-driving vehicles ultimately will integrate onkhổng lồ U.S. roadways by progressing through six levels of driver assistance giải pháp công nghệ advancements in the coming years. This includes everything from no automation (where a fully engaged driver is required at all times), to lớn full autonomy (where an automated vehicle operates independently, without a human driver).

Levels of AutomationWho does what, whenPlain language description of the SAE levels of automation
Level 0The human driver does all the driving.
Level 1An advanced driver assistance system (ADAS) on the vehicle cansometimes assistthe human driver with either steering or braking/accelerating, but not both simultaneously.
Level 2An advanced driver assistance system (ADAS) on the vehicle canitself actually controlboth steering và braking/accelerating simultaneously under some circumstances.The human driver must continue to pay full attention (“monitor the driving environment”) at all times & perform the rest of the driving task.
Level 3An automated driving system (ADS) on the vehicle can itself perkhung all aspects of the driving task under some circumstances.In those circumstances, the human driver must be ready to take back control at any time when the ADS requests the human driver khổng lồ bởi so.In all other circumstances, the human driver performs the driving task.
Level 4An automated driving system (ADS) on the vehicle can itself perkhung all driving tasks và monitor the driving environment – essentially, vì all the driving – in certain circumstances. The human need not pay attention in those circumstances.
Level 5An automated driving system (ADS) on the vehicle can do all the driving in all circumstances.The human occupants are just passengers and need never be involved in driving.


The safety benefits of automated vehicles are paramount. Automated vehicles’ potential lớn save lives và reduce injuries is rooted in one critical và tragic fact: 94%of serious crashes are due to lớn human error. Automated vehicles have sầu the potential to lớn remove sầu human error from the crash equation, which will help protect drivers và passengers, as well as bicyclists and pedestrians. When you consider more than 35,000people diein motor vehicle-related crashes in the United States each year, you begin lớn grasp the lifesaving benefits of driver assistance technologies.

Economic & Societal Benefits

Automated vehicles could deliver additional economic & additional societal benefits. A study showed motor vehicle crashes in 2010 cost $242 billion in economic activity, including $57.6 billion in lost workplace productivity, & $594 billion due khổng lồ loss of life & decreased unique of life due khổng lồ injuries. Eliminating the vast majority of motor vehicle crashes could erase these costs.

Efficiency & Convenience

Roads filled with automated vehicles could also cooperate khổng lồ smooth traffic flow và reduce traffic congestion. Americans spent an estimated 6.9 billion hours in traffic delays in 2014, cutting inlớn time at work or with family, increasing fuel costs & vehicle emission. With automated vehicles, the time và money spent commuting could be put lớn better use. A study stated that automated vehicles could free up as much as 50 minutes each day that had previously been dedicated to lớn driving.


While its full societal benefits are difficult to lớn project, the transformative potential of automated vehicles & their driver assistance features can also be understood by reviewing U.S. demographics & the communities these technologies could help khổng lồ tư vấn.

For example, automated vehicles may also provide new mobility options to lớn millions more Americans. Today there are 49 million Americans over age 65 and 53 million people have some khung of disability.

In many places across the country employment or independent living rests on the ability khổng lồ drive sầu. Automated vehicles could extover that kind of freedom to lớn millions more. One study suggests that automated vehicles could create new employment opportunities for approximately 2 million people with disabilities.

Automated or “self-driving” vehicles are a future công nghệ rather than one that you’ll find in a dealership tomorrow or in the next few years. A variety of technological hurdles have sầu to lớn be cleared, và other important issues must be addressed before these types of vehicles can be available for sale in the United States. The Department of Transportation is committed to supporting the innovators who are developing these types of vehicles lớn ensure their safe testing & deployment before they are available lớn consumers.

Automated vehicles and driver assisting technologies (including those already in use on the roads) have the potential to reduce crashes, prsự kiện injuries, và save lives. Of all serious motor vehicle crashes, 94 percent are due to human error or choices. Fully automated vehicles that can see more & act faster than human drivers could greatly reduce errors, the resulting crashes, và their toll.
