As a Minnesota criminal defense attorney focused on DWI cases, I keep a close eye on trends that affect drivers across our state. Recently, two seemingly unrelated headlines from the Star Tribune caught my attention, and together, they paint a concerning picture for road safety. One article detailed a guide for older adults rediscovering newly-legalized cannabis, while another reported that Minnesotans are failing their driving tests at a rate not seen in years. The intersection of these two trends creates a potential ‘perfect storm’ for an increase in Driving While Impaired (DWI) charges, and it’s something every Minnesotan should be aware of.

The legalization of recreational cannabis in Minnesota is a significant social and legal shift. For many adults, particularly older individuals who may not have used it since their youth, this new freedom presents an opportunity for exploration. While the state has rightly put regulations in place, a crucial point often gets lost in the conversation: legal to use does not mean legal to use and drive. The core principle of Minnesota’s DWI law remains unchanged. It is illegal to operate a motor vehicle while under the influence of any substance that impairs your ability to drive safely. This includes alcohol, prescription drugs, and, of course, cannabis.
Unlike alcohol, which has a well-established scientific and legal framework for measuring impairment (the 0.08 BAC limit), cannabis impairment is more complex to prove and to self-assess. The effects of THC, the psychoactive component in cannabis, can vary dramatically from person to person based on tolerance, consumption method, and potency. A person might feel ‘fine’ but have significantly slowed reaction times, impaired judgment, and reduced coordination, all of which are critical for safe driving. A traffic stop that leads an officer to suspect impairment can result in field sobriety tests and a subsequent arrest, regardless of whether you feel intoxicated.
Now, let’s consider the second headline: the alarming drop in driving test pass rates. This suggests that basic knowledge of traffic laws and fundamental driving skills may be declining across the board. When you combine this potential erosion of driving competency with the introduction of a newly legalized impairing substance, the risk for everyone on the road multiplies. A driver who is already less confident with road rules or maneuvering a vehicle is at an even greater disadvantage when their cognitive functions are impaired by cannabis.
This convergence of factors creates a scenario where well-intentioned people can easily find themselves facing serious legal trouble. You might be a responsible adult trying a legal product for the first time in decades, completely misjudging how it will affect you hours later. You might be a driver who is already a bit rusty on the rules of the road. A minor traffic infraction could escalate into a DWI investigation if an officer smells cannabis or observes signs of impairment. The consequences of a DWI conviction are severe and long-lasting, including license revocation, hefty fines, potential jail time, mandatory classes, and a permanent criminal record that can impact employment and housing opportunities.
Navigating this new landscape requires caution and education. It is imperative to understand that if you choose to consume cannabis, you must have a plan that does not involve driving. The only safe number is zero. However, mistakes happen and good people can find themselves in bad situations. If you are arrested for a DWI, whether for alcohol or cannabis, it is critical that you do not face the charges alone. The science of cannabis impairment testing is still evolving, and the legal arguments are complex. You need an experienced DWI defense attorney who understands the law, the science, and your rights. My job is to ensure your case is handled fairly and to fight for the best possible outcome.
