Duid (driving Under The Influence of Drugs)

DUID or driving under the influence of drugs assert a driver is impaired if they have any detectable level of a controlled substance in their blood while they are operating a motorized vehicle. Exceptions can be made for legal medications (in which the driver has a legal prescription). Blood tests can be used to detect the illegal controlled substance. Law enforcement officers may also use a variety of field sobriety tests to prove and corroborate evidence of the driver's physical or mental impairment to operate a motorized vehicle.

In some states, such as California, drivers may be arrested for driving under the influence of any type of illegal or legal drug if it is can be proven that they were unable to operate a motor vehicle as safely as a sober driver. Drivers who are arrested for DUID should contact a DUI lawyer. DUID cases and DUI (driving under the influence) are prosecuted in much the same way, and a DUI attorney can review the arrest records and blood alcohol concentration procedures to ensure the DUID arrest was administered correctly.
