Abstract
A system for providing a warning when at least two vehicles, first and second vehicles, are near a common collision point. The system includes closed loop verification between a first vehicle and a common collision point. The system includes a first transmitter for transmitting a first radio frequency signal, a first receiver for receiving the first radio frequency signal at the common collision point, a second transmitter for transmitting a second radio frequency signal from the common collision point to the first vehicle and to any approaching vehicles, a second receiver in a vehicle which can receive the second radio frequency signal and indicate that the first and second vehicles are near a common collision point, and a third receiver in the first vehicle for receiving the second radio frequency signal and for providing an indication that a closed loop between the first vehicle and the common collision point is functioning properly.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
