DRUGGED-DRIVING LAWS

* Current law in most states, including Tennessee, makes it difficult to
identify, prosecute or convict drugged drivers, according to a recent study
funded by The Robert Wood Johnson Foundation's Substance Abuse Policy
Research Program.

* Eight states have enacted zero-tolerance laws. Arizona, Georgia,
Indiana, Illinois, Iowa, Minnesota, Rhode Island and Utah make the presence
of any prohibited drug or substance in a driver's body while he/she is
driving a DUI violation.

* Only Nevada has set specific percentages of prohibited drugs or
substances other than alcohol as a violation of its DUI statute.

* Texas makes it illegal for chemically dependent persons who are a danger
to themselves or for those who are addicted to a controlled substance to
receive a driver's license.

* California, Colorado, Idaho, Kansas and West Virginia make it illegal
for any drug addict or habitual user of drugs to drive a vehicle in their
states.

* North Carolina and South Dakota make it illegal for any person under 21
to drive with any amount of a prohibited drug or substance in his/her body.
