How the PDPS Works
1. Maryland sends an inquiry.
4. Virginia sends
driver license status
to Maryland.
2. NDR searches its database
and responds with the
number of matches.
3b. If a match is found,
NDR sends a request to
Virginia to send the driver
license status to Maryland.
3a. If no match is found,
NDR notifies the state.
Process is complete.

48 million pointers on the PDPS database
98 million transactions processed for State and
federal users in CY 2010
78% increase in transactions from 2002 to 2010
More and More federal agencies are figuring ways to
side step the access legislation.

This will be dealt with in the next round of rule makings
