CA law closes urine test 'loophole'

Drivers suspected of being under the influence of drugs will no longer be allowed to request a urine test. That's the results of a rewrite of a California law. They must instead take a blood test if asked. The new law closes what officials say is a legal loophole: Some drugged-driving arrestees demand a urine test, then argue in court that the urine test is unreliable.Prosecutors say blood tests are better at determining if drugs are in a person's system.
