While many previous efforts have focused on information delivery, METR focuses more on the pipeline to ensure that it can deliver rules of the road in a trustworthy manner. For example, while off-the-shelf navigation systems frequently will display a speed limit to the driver, the information displayed is only informative; the driver is still responsible for complying to the posted speed limit, even if the navigation system is inaccurate. Automated Driving Systems require more trustworthy information to complete their tasks.

While the title of the standards series is "Management of Electronic Traffic Regulations (METR)", the intent is that it will be capable of providing trustworthy advisories and guidance in addition to regulations. This website defines the term "rule" to represent the aggregation of these three terms.

Within its scope, METR will support both pre-announced rules, which can be accessed well in advance of the location and time of need, and emergent rules, which reflect recent changes (e.g., perhaps an instant before a vehicle reaches the affected location).

METR should be able to support virtually any rule that needs to be conveyed to virtually any transport user. For example, the graphic depicts rules for freight vehicles, ride sharing, kerbside usage, micromobility operations, vulnerable road users (VRUs), public transport usage, lane usage, public-area mobile robots (PMRs), and road works. This information and more needs to be conveyed to all transport user systems; sample user systems shown in the graphic include nomadic devices, PMRs, driver support systems, and ADS-equipped vehicles.
