Driving High Carries DUI Consequences

As marijuana remains legal for recreational use by adults in Illinois, law enforcement officials are reminding residents that driving under the influence of cannabis remains illegal and carries the same penalties as driving under the influence of alcohol or other drugs.

The Illinois Sheriffs’ Association has renewed its warning to motorists that impairment of any kind behind the wheel is prohibited under state law and poses a risk to public safety. Officials stress that legalization of cannabis does not change DUI laws.

“Cannabis has been legalized, driving impaired is still a DUI,” the association said in a recent statement. “If you choose to drive while impaired, you are putting yourself at significant legal risk and liability. It is a myth that driving under the influence is legal, safer, or less risky than driving while drunk.”

Under Illinois law, adults 21 and older may legally possess and use marijuana. However, operating a motor vehicle while impaired by cannabis is still considered a DUI offense. Law enforcement officials note that marijuana can slow reaction times, impair judgment and reduce coordination, increasing the likelihood of crashes that can endanger drivers, passengers and others on the roadway.

Penalties can be severe. Officials say that if a driver who is impaired by cannabis causes a crash that results in injury, they could face a prison sentence of up to 12 years. If a crash results in a death, a sentence can extend up to 14 years.

State law also makes it illegal to drive if a person has consumed any substance that “renders the person incapable of safely driving.” In addition, it is unlawful for any driver or passenger to use cannabis inside a vehicle.

If a motorist is stopped and an officer suspects impairment, law enforcement may administer standardized field sobriety tests and validated roadside chemical tests. Authorities emphasize that Illinois operates under an implied consent law, meaning drivers automatically agree to submit to certain chemical tests — including breath, blood or urine testing — to determine impairment. Refusal to submit to testing, or failing a test, can result in an automatic suspension of driving privileges.

“Marijuana use impairs your ability to drive safely. Driving while impaired by marijuana or any other substance is dangerous and illegal,” said Sheriff Paula Crouch. “Our office will continue enforcing DUI laws to protect the safety of our community.”

Sheriff Crouch and the Illinois Sheriffs’ Association are encouraging drivers to plan ahead if they intend to use marijuana, similar to recommendations involving alcohol. Officials advise arranging for a sober driver, using a rideshare service or securing another safe way home, emphasizing that the safest choice is always to drive sober.
