Having a doctor’s prescription for Vicodin or any other legal drug is not a valid defense to a charge of driving under the influence.  California Vehicle Code section 23152(a) clearly states that it is against the law to operate a motor vehicle when you are under the influence of a drug.  The law does not make any exceptions for those having a valid prescription.  Similarly, having a prescription for marijuana does not permit a person to operate a motor vehicle when they are under the influence of marijuana.

The prosecution must prove two things:

  • The defendant drove a vehicle; and
  • When the defendant drove, the defendant was under the influence of a drug

Unlike alcohol, where a breath or blood test can determine your blood alcohol content, there is no quick method for law enforcement to determine the specific amount of drug content in your body; other than, whether an individual tested positive or negative for a drug.

As such, it can be difficult for the prosecution to prove you were actually “under the influence of a drug” when driving a vehicle. The strongest defense is that you were not operating a motor vehicle while under the influence of a drug.

For example, you can consume a prescription drug like Vicodin and continue to operate a motor vehicle in a safe manner.  Just because someone consumes a dose of Vicodin does not mean they are “under the influence of a drug.”  Therefore, the prosecution will look at objective factors of the defendant’s driving patterns to determine if the driver was under the influence of a drug.  Specifically, the prosecutor will see if the defendant was speeding, driving erratically, weaving between traffic or driving on the wrong side of the road.
