Robert L. Marshall Attorney At Law DUID Legal Counsel

Under California law, it is illegal to drive while under the influence of drugs as well as while under the combined influence of alcohol and drugs. These offenses are listed separately under the Vehicle Code. California law includes any drug or medicine that can impair a driver’s full possession of his or her faculties – that means any drug, whether legal, illegal, or prescribed by a doctor.

For example, you may be arrested for DUID for driving under the influence of:

  • Marijuana
  • Vicodin or any opiate
  • Methamphetamine
  • Sleeping pills
  • Over-the-counter allergy or cold medicines

DUID is generally charged as a misdemeanor with penalties similar to those of a regular DUI. It is charged as a felony, however, if it is your fourth or subsequent DUI offense, if you have a prior felony DUI conviction, or if you injured or killed someone as a result of drugged driving.

Potential defenses against a DUID charge may include

  • Lack of probable cause for pulling you over
  • Improper conduct of field sobriety tests
  • Improper blood testing
  • Medical and physical conditions that can look like drug impairment
  • Invalid or inconclusive test results

We encourage you to take advantage of the knowledge and skills our Chico prescription drug DUI defense lawyer has to offer.
