Traffic accidents are devastating life events for drivers and passengers alike. Those who are injured not only deal with severe physical pain, but they must also cope with immense emotional stress and financial burdens. Mounting medical expenses, lost income, and uncertainty about the future weigh heavily on a family.

Learning that another driver’s choice to drive under the influence of drugs caused your preventable accident only compounds this difficult situation.

If an impaired driver caused your injuries, Missouri and Illinois law entitles you to seek compensation in civil court. Let an experienced St. Louis drugged driving accident lawyer investigate your case, advocate for your rights, and litigate your case in court if necessary.

Bi-State Intoxicated Driving Laws: Missouri & Illinois

Both Missouri and Illinois treat drugged driving precisely the same way they treat drunk driving. Under the law, drug and alcohol use behind the wheel is entirely illegal.

Missouri DWI Laws

Under Missouri law, a person convicted of a DWI faces large fines, mandatory alcohol assessments, and jail time. Missouri explicitly defines intoxication as operating a vehicle “under the influence of alcohol, a controlled substance, or drug, or any combination thereof.”

Prescription Medication Impairment

Missouri and Illinois laws provide extensive lists of controlled substances. However, it is crucial to note that legal prescription medications frequently lead to civil liability. Even when following a doctor’s advice, legal prescription drugs can render a driver intoxicated if the medication impairs normal functions, such as sight, hearing, and reaction times.

If a driver operates a vehicle under the influence of legally prescribed medication and causes a crash, a jury will hold them negligent and financially responsible for your damages.

Common Drugs Found in Intoxicated Drivers

The substances found in intoxicated drivers vary greatly. In some instances, the driver might be taking legal prescription drugs, while in other cases, the driver might be abusing illegal narcotics. The most common substances involved in St. Louis drugged driving crashes include:

 1. Cannabis and Marijuana

Next to alcohol, cannabis remains the drug most frequently found in impaired drivers. Although Illinois recently approved the recreational use of marijuana, and Missouri allows medicinal use, driving under the influence remains strictly illegal. Cannabis severely impairs judgment and reaction times. According to the Governors Highway Safety Association, nearly 38 percent of drug-tested fatally injured drivers test positive for some form of marijuana.

 2. Prescription Opioids

Doctors frequently prescribe opioids for pain management, including oxycodone, hydrocodone, and fentanyl. While patients have legitimate medical needs for these medications, it is illegal to drive while under their influence. Driving while taking strong opiates constitutes absolute negligence.

3. ADHD/ADD Medications

Medications used to treat ADHD, such as Ritalin and Adderall, are psychotropic. Unfortunately, drivers frequently abuse these medications as stimulants. Any abuse of these medications that results in driving under the influence establishes driver negligence.

4. Antidepressants & Benzodiazepines

Over 25 million adults across the nation take antidepressants (like Prozac and Zoloft) or sleep aids (like Ambien and Xanax). When a patient starts a new prescription, their body must adjust to the chemical changes. If these powerful drugs cause drowsy driving or sudden fatigue behind the wheel, the driver remains liable for the resulting crash.
