Definition: Most states now have passed laws that require vehicle drivers to submit to a chemical test -- breath, blood or urine testing -- if they are suspected of DUI. If the driver refuses to submit to the test, implied consent laws carry penalties such as mandatory suspension of a driver's license.
Some believe that implied consent laws violate a driver's Fifth Amendment right against self-incrimination, but thus far those laws have been upheld when challenged in the courts.
Also Known As: Mandatory Test
Examples: In most states, if you are driving a vehicle, you have given implied consent to be tested for intoxication.
