5 Things You Should Know About Legal Marijuana And Driving

Connecticut, like many states, has legalized recreational marijuana. While this change has brought new freedoms, it has also introduced new risks—particularly when it comes to driving. Just as with alcohol, using marijuana can impair judgment, reaction time, and coordination, all of which are critical behind the wheel. To prevent getting into a New Haven auto accident you should know these five important things about marijuana and driving.

1. Driving Under the Influence of Marijuana Is Illegal

Even though marijuana is legal for adults in Connecticut, it’s still illegal to drive while impaired by it. State law treats marijuana-impaired driving the same way it treats alcohol-impaired driving. If law enforcement suspects you are under the influence, you can be stopped, tested, and charged with a DUI. Penalties can include fines, license suspension, and even jail time—consequences that can affect your future long after a traffic stop.

2. Marijuana Impairment Can Be Difficult to Measure

Unlike alcohol, which can be measured with a breathalyzer, marijuana impairment is not as easy to test on the spot. THC, the psychoactive compound in marijuana, can remain in your system for days or even weeks. This means a blood or urine test may not reflect whether you were actually impaired at the time you were driving. Because of this, law enforcement often relies on field sobriety tests and officer observations to determine impairment, which can be subjective and complicated.

3. Marijuana Slows Reaction Time and Affects Judgment

Research shows that marijuana use can significantly impair reaction time, hand-eye coordination, and the ability to focus—all skills necessary for safe driving. Even if you feel “in control,” marijuana can alter your perception of time and distance, increasing the likelihood of accidents. In a busy city like New Haven, where pedestrians, cyclists, and heavy traffic are common, impaired driving can quickly become dangerous.

4. Insurance and Liability Issues Can Be Serious

If you cause a car accident while under the influence of marijuana, the legal and financial consequences can be severe. Beyond criminal charges, you may be held civilly liable for damages, including medical bills, lost wages, and pain and suffering of others involved. Insurance companies may deny coverage if you were driving while impaired, leaving you personally responsible for significant costs. For accident victims, proving that another driver was impaired by marijuana can be key to pursuing compensation.

5. Legalization Does Not Equal Safety

The legalization of marijuana has created a false sense of security for some drivers. Just because something is legal does not mean it is safe—or legal to use in every context. Much like alcohol, responsible use is essential. If you plan to use marijuana, make arrangements for safe transportation. Call a ride service, designate a sober driver, or wait until you are no longer impaired before getting behind the wheel.

Legal marijuana has changed the landscape in Connecticut, but it has not changed the dangers of impaired driving. If you’ve been injured in a New Haven auto accident involving a driver impaired by marijuana, it’s important to understand your rights. A personal injury attorney can help you navigate the legal system, pursue compensation, and hold negligent drivers accountable.
