If you use alcohol or drugs your ability to drive will be impaired—which makes it unsafe for you, and others, to be on our roads. So make the right decision about driving, and alcohol and drugs. Plan ahead. Use a designated driver or public transportation to make sure you arrive safely. And Drive Well, Vermont.

Plan ahead if you are using alcohol or drugs so you can arrive safely. And Drive Well, Vermont.

Driving under the influence of alcohol is not only dangerous, it's also illegal - and the State Highway Safety Office (SHSO) along with all Vermont Law Enforcement Agencies are dedicated to enforcing the law and keeping you and our roads safe.

Impaired driving is a serious problem threatening the safety of all users of Vermont's highways. Fortunately, there are simple ways to deal with this problem. Just plan ahead if you need to travel, and make sure you have a designated driver or access to public transportation.

Any driver who operates a motor vehicle under the influence (“DUI”) will face serious legal and financial consequences.  It is a common misperception that a driver can only be charged and found guilty of DUI when they have a Blood Alcohol Concentration (“BAC”) at above a .08.  However, a driver can be charged and be found guilty of DUI when they are affected by alcohol to the slightest degree even when their BAC is below .08.    

Different drugs affect drivers in different ways. However, those that impair judgment, alertness, concentration or motor skills are considered just as (if not more) dangerous than alcohol. Prescription drugs, over the counter medications, illegal drugs, and cannabis alone or in combination with each other and/or with alcohol can cause impairment.  These substances alone and in combination can have a measurable physiological effect that impair your ability to drive and react quickly in critical situations. They can affect your reaction time, short-term memory, hand-eye coordination, concentration, and perception of time and distance. Even if you think you're good to drive, you may not be. Any form of impaired driving is illegal.   

When you drive impaired, you put yourself, your passengers and other users of the highways at risk of serious injury or death.  Always plan ahead to find a sober ride. And Drive Well, Vermont.

Our Efforts to Increase Awareness and Enforcement of Impaired Driving

National Campaigns - Vermont participates in the National Highway Traffic Safety Administration (NHTSA) National Campaigns for “Buzzed Driving is Drunk Driving ” to raise DUI social awareness and the “Drive Sober or Get Pulled Over” campaign for enforcement; to deter impaired driving and reduce the number of alcohol-related motor vehicle crashes. Paid media in the form of TV, radio, print, and digital ads are used to reinforce the legal, financial and personal consequences of driving under the influence of alcohol.  If You Feel Different, You Drive Different.

Checkpoints – These allow police to briefly stop vehicles at specific, highly visible locations to see if the driver is impaired. Police may stop all or a certain portion of drivers. Breath tests may be given if police have a reason to suspect the driver is intoxicated.

Ignition interlocks – This is a unit installed in cars used to measure alcohol on the driver’s breath. Interlocks keep the car from starting if the driver has a BAC above a certain level, usually 0.02%. They’re used for people convicted of drunk driving and are highly effective at preventing repeat offenses while installed. Mandating interlocks for all offenders, including first-time offenders, will have the greatest impact.

Working with our partners  - Prescription and over-the-counter (OTC) medication use has become a big issue in the last few years. Eight out of ten senior drivers age 65 and older take medications on a regular basis. Tools like Roadwise Rx, a free, web-based tool developed by the AAA Foundation for Traffic Safety that anyone can use to explore how medications may affect safe driving.

Attitude Survey - The SHSO annually conducts a driver attitude survey. This is done to acquire attitudes of Vermont drivers about various subjects including enforcement of the laws, impaired driving, seat belt use, texting and driving, child car seat use, and general personal driving behavior.

Drug Recognition Experts (DRE) - The State of Vermont started their involvement in the DRE program in 2005 when the first five DREs were trained. The program has now grown to thirty-eight certified DREs from state, county, and municipal law enforcement agencies from throughout the State of Vermont.

During the holidays, the number of travelers on our nation’s roads peaks as friends and family gather to celebrate. As a result of holiday parties and gatherings, more drivers are impaired by alcohol, too. Unfortunately, fatalities resulting from accidents crashes involving alcohol-impaired drivers have become so predictable that many state highway patrol agencies around the country now issue fatality estimates, which usually prove to be all too accurate.

Remember, Law Enforcement officers in Vermont are trained to be looking for driver Impairment due to alcohol or drugs. Many are specially trained Drug Recognition Experts (DREs). These officers have the ability to detect physical signs of drug impairment. DREs are viewed as one of the most effective law enforcement tools in efforts to reduce drugged driving.

Officers are also on the lookout for aggressive and speeding drivers who - by the very nature of their risk-taking behavior - are more likely to be under the influence of alcohol, drugs, or both.
