Federal Motor Vehicle Safety Standards
The Federal Autonomous Vehicle Policy includes no new rules or regulations—only guidance—for states. Although it will likely be many years before fully autonomous vehicles see widespread deployment, there is much for states to accomplish in areas such as traffic enforcement, insurance, registration, licensing and more.
Self-driving cars, also known as autonomous vehicles, have the potential to revolutionize how—and how safely—people get from point A to B. As the technology continues to develop, federal, state and local governments are studying, debating and addressing the prospective benefits and challenges of this burgeoning transportation revolution. They also see the production of autonomous vehicles as a possible economic boon for their state.
But questions about exactly how these vehicles will operate and interact on the roadway persist. Some are concerned that driverless vehicles could pose a danger to other motorists and pedestrians, particularly when there is a mix of driverless and traditional vehicles on the road. Others are concerned about cybersecurity and privacy. State Action Eleven states and the District of Columbia have passed legislation related to autonomous vehicles.
Additionally, governors in Arizona and Massachusetts have issued executive orders. These laws vary in scope, however. California, Florida, Michigan and Nevada passed comprehensive regulations governing the testing of autonomous vehicles.
Nevada, the first state to pass an autonomous vehicle law in , allows autonomous vehicles to be tested in the state, but the vehicle must be registered, insured and have a certificate of compliance issued by the state Department of Motor Vehicles.
In California, the Contra Costa Transportation Authority is authorized to test the first fully autonomous vehicle not equipped with a steering wheel, brake pedal or accelerator on certain public roads. Michigan enacted a four-bill package in that allows autonomous vehicles to be driven on public roads, eases testing restrictions for manufacturers, allows commercial use of autonomous vehicle technology and establishes the American Center for Mobility, a testing facility for connected and driverless cars.
Intended for occupant use means, when used in reference to the adjustment of a seat, positions other than that intended solely for the purpose of allowing ease of ingress and egress of occupants and access to cargo storage areas of a vehicle. Rear head restraint means, at any rear outboard designated seating position , a rear seat back, or any independently adjustable seat component attached to or adjacent to a seat back, that has a height equal to or greater than mm, in any position of backset and height adjustment , as measured in accordance with S5.
Top of the head restraint means the point on the head restraint with the greatest height. Except as provided in S4.
Whenever a range of measurements is specified, the head restraint must meet the requirement at any position of adjustment within the specified range. In each vehicle other than a school bus , a head restraint that conforms to either S4. In each equipped with rear outboard head restraints, the rear head restraint must conform to either S4.
In each school bus , a head restraint that conforms to either S4. At each designated seating position incapable of seating a 50th percentile male Hybrid III test dummy specified in 49 CFR part , subpart E, the applicable head restraint must conform to S4.
US FMVSS 202 Final Rule
Each head restraint located in the front outboard designated seating position and each head restraint located in the rear outboard designated seating position must conform to paragraphs S4. Compliance is determined for the height requirements of S4.
The requirements of S4.
In those instances in which this head restraint cannot attain the required height , when measured in accordance with S5. Notwithstanding this exception, when measured in accordance with S5.
When measured in accordance with S5. For adjustable restraints, the requirements of this section must be met with the top of the head restraint in any height position of adjustment between mm and mm, inclusive.
If the top of the head restraint , in its lowest position of adjustment , is above mm, the requirements of this section must be met at that position. If the head restraint position is independent of the seat back inclination position, the head restraint must not be adjusted such that backset is more than 55 mm when the seat back inclination is positioned closer to vertical than the position specified in S5.
All head restraints must meet limits for gaps in the head restraint specified in S4. For gaps between the seat and head restraint , adjustable head restraints must meet either the limits specified in S4.
The following option is only available to head restraints that can move with respect to the seat. When the anterior surface of the head restraint is impacted in accordance with S5. When tested in accordance with S5. During application of the initial 50 N reference load, as specified in S5.
When the head restraint is tested in accordance with S5. At each forward-facing outboard designated seating position equipped with a head restraint , the head restraint adjusted midway between the lowest and the highest position of adjustment , and at any position of backset adjustment , must conform to the following: S4. Limit posterior angular rotation between the head and torso of the 50th percentile male Hybrid III test dummy specified in 49 CFR part , subpart E, fitted with sensors to measure rotation between the head and torso , to 12 degrees for the dummy in all outboard designated seating positions; b Head injury criteria.
Limit the maximum HIC15 value to HIC15 is calculated as follows - For any two points in time, t1 and t2, during the event which are separated by not more than a 15 millisecond time interval and where t1 is less than t2, the head injury criterion HIC15 is determined using the resultant head acceleration at the center of gravity of the dummy head, a r, expressed as a multiple of g the acceleration of gravity and is calculated using the expression: 4. The head restraint must have the lateral width specified in S4.
A rear head restraint may be adjusted to a position at which its height does not comply with the requirements of S4. However, in any such position, the head restraint must meet either S4.Width 1.

Given the efforts concerning side-impact dummy harmonization and on pole side-impact testing, the Forum decided in November to remove this issue temporarily from its agenda.
For gaps between the seat and head restraint , adjustable head restraints must meet either the limits specified in S4.
Maximum load the same, seat back cannot fail. The owner's manual must clearly identify which seats are equipped with head restraints; b If the head restraints are removable, the owner's manual must provide instructions on how to remove the head restraint by a deliberate action distinct from any act necessary for upward adjustment , and how to reinstall head restraints; c Warn that all head restraints must be reinstalled to properly protect vehicle occupants.
These include additional funding to support more research, a larger network of experts, premarket approval authority for vehicles and software upgrades after vehicles sell.
The regulatory text see the GAR pipeline has been adopted and is undergoing the six-month waiting period before its finalization in June Rear head restraint means, at any rear outboard designated seating position , a rear seat back, or any independently adjustable seat component attached to or adjacent to a seat back, that has a height equal to or greater than mm, in any position of backset and height adjustment , as measured in accordance with S5.
Seat back angle set at 25 degrees. When the head restraint is tested in accordance with S5.
