Yes. 23152 of the California vehicle code defines what driving under the influence is. The arrest is based on the arresting officer's opinion of whether or not you can safely operate a vehicle.
That phrase refers to the agency for which the arresting officer works.
A DUI (Driving Under the Influence) checkpoint is a specific location a police officer will assess driver's alcohol consumption. So as a driver approaches a checkpoint, the police officer will first observe your behavior and search for signs of alcohol consumption. If the police officer finds a driver to be intoxicated, the police officer will conduct a series of assessments regarding to the driver's abilities in coordination.
He/she is suspected of driving under the influence, and the officer either issues a breathalyzer test or blood test.
In many states there is no "request" about it. In most (all?) states your signature on the license application is acknowledgement of your acceptance of being directed to undergo a sobriety screening when sufficient probable cause exists to raise a question in the officer's mind that you are under the influence. Refusal of the officers "request"/directive will usually result in an automatic suspension of your driving privileges for a stated minimum amount of time (can vary by state).Added: To answer your question, officers use Field Sobriety Tests (reciting a portion of the alphabet or walking down a line), breathalyzer tests, and blood tests to test for intoxication or impairment.

Negative. Only if the officer has reasonable cause to believe that the driver is or could be under the influence of a behavior changing substance.
The officer can require you to perform field sobriety tests and submit to the breathalyzer on the scene. If you blow above .08 BAC you will be detained and taken to the station to submit to another breathalyzer or possibly a blood draw.
