The Future Trends in Drug Impairment Testing.

When it comes to driving under the influence, most people immediately think of alcohol. However, there’s another substance that causes just as much harm on the road – drugs. Driving under the influence of drugs is a serious offense that can result in severe injuries or even death. This is where drug impairment test comes in. In this blog post, we’ll go over all you need to know about DIT – from what it is, how it works, the different types of tests, and its importance.

What is Drug Impairment Testing?

Drug Impairment Testing is a standardized procedure that’s used to determine if a person is impaired by drugs while driving. This non-invasive procedure is conducted by specially trained Drug Recognition Experts (DRE) who can assess the physical and mental state of the driver. The results of the DIT are only used as evidence in court and cannot be used for disciplinary or insurance purposes.

How Does Drug Impairment Testing Work?

The DRE will usually conduct a 12-step procedure to determine if a driver is impaired. The process starts with a preliminary evaluation of the driver’s eyes, vital signs, and muscle tone. Then, the evaluator will ask the driver various questions to assess their short-term memory and cognitive abilities. Depending on the results of the evaluation, the DRE may conduct additional tests such as the Romberg Balance, Finger to Nose, and Walk and Turn tests.

Types of Drug Impairment Testing:

There are generally three types of DITs used to determine the presence of drugs: urine, blood, and saliva tests. Urine testing is the most common, but it’s not usually reliable in determining recent use. Blood testing is the most accurate and can determine the amount of drugs in the driver’s system. Saliva testing is the most non-invasive and can detect drugs within 24 hours.

Why is Drug Impairment Testing Important?

Drug-impaired driving is a significant problem that’s on the rise. According to the National Highway Traffic Safety Administration, drug-related deaths increased by 27% from 2007 to 2015. As such, the importance of DIT cannot be overemphasized. By detecting drug-impaired drivers, law enforcement agencies can prevent accidents and deter people from driving while under the influence.


Drug Impairment Testing is a vital tool that’s used by law enforcement agencies to determine if a driver is impaired by drugs. This non-invasive procedure has several benefits that stem from its accuracy, reliability, and comprehensiveness. As drug-impaired driving continues to be a significant problem, more people need to be aware of DIT and its benefits. If you know someone who’s been arrested for drug-impaired driving, seeking legal counsel is crucial. An experienced lawyer can help you understand your rights and navigate the legal system.
