who is the issuing authority on a drivers license
Driver's license In the United States and Canada, driver's licenses are issued by the states and provinces (or territories), respectively, and do not look the same nationwide. They are also used as a de facto or government-issued identification document for the holder. Most government issuers of driver's licenses also provide a government-issued identification card with similar attributes to a driver's license to those residents within their jurisdictions who do not have or maintain a valid driverâ€™s license, making it easier for them to do things such as open a bank account, and perform any other activities that require official identification. Identification cards serve as government-issued photo ID but do not enable a person to operate a motor vehicle, a fact typically noted on the ID via the phrase 'Not a driver's license' or similar wording. This type of photo ID is referred to as a Photo card in some jurisdictions (for example, Ontario Photo Card). Government-issued ID cards are also issued to out-of-state residents e.g. college students enrolled in an institution of higher education outside their state of residence e.g. a domiciled Texas resident enrolled at UCLA where the individual retains their Texas driver license and holds a California state issued ID card (as mentioned above e.g. bank account and financial affairs); also applicable to those who own business assets and not domiciled in a state or city as a resident e.g. one domiciled in Los Angeles and owns either a business or real estate property in Florida). In the United States no individual can hold two valid driver licenses, e.g. a Texas and California driver license held simultaneously, since some U.S. states do not collect personal income taxes e.g. Texas, Florida while California has a personal state income tax.[clarification needed]
Medical prescription National or local (i.e. state or provincial) legislation governs who can write a prescription. In the United States, physicians (either M.D., D.O., or D.P.M.) have the broadest prescriptive authority. All 50 states and the District of Columbia allow licensed certified Physician Assistants (PAs) prescription authority (with some states, limitations exist to controlled substances). All 50 states allow registered certified nurse practitioners and other advanced practice registered nurses (such as certified nurse-midwives) prescription power (with some states including limitations to controlled substances).[11][12] Many other healthcare professions also have prescriptive authority related to their area of practice. Veterinarians and dentists have prescribing power in all 50 states and the District of Columbia. Clinical pharmacists are allowed to prescribe in some states through the use of a drug formulary or collaboration agreements. Florida pharmacists can write prescriptions for a limited set of drugs.[13] In all states, optometrists prescribe medications to treat certain eye diseases, and also issue spectacle and contact lens prescriptions for corrective eyewear.[14] Several states have passed RxP legislation, allowing clinical psychologists (PhDs or PsyDs) who are registered as medical psychologists and have also undergone specialized training in script-writing to prescribe drugs to treat emotional and mental disorders. Chiropractors may have the ability to write a prescription, depending on scope of practice laws in a jurisdiction.
