Effects of alcohol and drugs
Alcohol and other impairing drugs figure in about 40 percent of fatal crashes, and any amount raises your crash risk. They reduce judgment, the brain's store of experience for new problems; vision, blurring, slowing focus, doubling images and weakening judgment of distance, speed and movement, affected from 0.02 BAC in every driver, and vision is the most important sense in driving; color distinction; and reaction time. The best advice is not to drive after any alcohol or drugs: impairment starts with the first drink, one drink can affect driving, one or more drinks make a person visibly impaired and arrestable, never let a friend or relative drive after drinking, and never mix drugs and alcohol, which react unpredictably. Illegal, over-the-counter and prescribed drugs all affect reflexes, judgment, vision and alertness like alcohol. Emotions raise risk too by interfering with thinking, attention and processing, so when overly worried, excited, afraid, angry or depressed, cool off with a walk or nap before driving, leave early, or let someone else drive.
Drivers under 21
Under 21 it is illegal to buy, possess or drink alcohol, whose effects are greater on drivers still learning, and every state has zero tolerance. A person aged 13 to 20 convicted of possessing or consuming alcohol or of being underage in a bar loses the license for one year on a first offense and two years on a second or later, and for a driver under 16 the court-ordered suspension runs one to two years from the 16th birthday. Under the Not-a-Drop Act, a driver under 21 with any measurable alcohol in the body is denied all driving privileges for six months on a first offense and, for a second within 10 years, two years or until 21, whichever is longer, even before ever holding a license; reinstatement after a Not-a-Drop suspension requires an assessment and recommendation from a substance abuse program, or proof of completing a Prime For Life DUI class.
Alcohol and the law
Above 0.05 BAC (0.04 for commercial drivers) you violate the law, and you also violate it below the limit if impaired to the degree that driving is unsafe. A first DUI conviction at 21 or older suspends the license 120 days, and a second or later two years; the division may begin the suspension on the 45th to 60th day after the arrest. A guilty or no-contest plea held in abeyance does not appear on the driving record or suspend a regular privilege, but it disqualifies a commercial privilege and counts as a prior offense with later ones, for DUI, reckless driving and automobile homicide. Under implied consent, driving a vehicle or motorboat means you will submit to a chemical test of breath, blood, urine or oral fluids when an officer asks; refusing revokes the license 18 months for a first offense and 36 months for later ones, and under 21 two years or until 21 for a first and 36 months or until 21 for later ones, whichever is longer. After any alcohol-related suspension or revocation you may apply anew after the period by paying the reinstatement and license fees, retaking the tests and possibly paying an administrative fee, and ignoring court orders keeps you suspended until they are met. An alcohol-restricted driver may not drive with any alcohol in the body: the status lasts 2, 3, 5 or 10 years depending on the offenses, or life after automobile homicide or felony DUI, running from the suspension or revocation for DUI, alcohol-related reckless driving, impaired driving, homicide, a per se arrest, refusal, driving with alcohol while restricted or driving without a required interlock; after reinstatement you drive fully, but a conviction for any measurable alcohol during the period revokes the license for one year. Operating a motorboat under the influence carries the same laws as a motor vehicle.
Ignition interlock, impound and interdiction
An interlock-restricted driver is suspended until an ignition interlock device is installed and the reinstatement fee paid, and removing the device early re-suspends the privilege. A first DUI conviction restricts you to an interlock-equipped vehicle for 18 months from conviction or the suspension's effective date, three years if under 21 at arrest; a second or later DUI, impaired driving or alcohol-related reckless conviction, or a refusal revocation, brings two years; felony DUI brings three years and automobile homicide 10 years. Driving without a required interlock can get the vehicle impounded and brings a citation whose conviction revokes the license for one year plus two more years of interlock; the device must be monitored at least every 60 days, and a missed monitoring or an attempt to start with 0.02 or more extends the requirement 60 days each time. An officer may impound the vehicle or motorboat of anyone arrested for DUI; the DMV notifies the owner, who pays towing, storage and administrative costs to recover it, an unclaimed vehicle is sold, the court may order the arrestee to pay, and a repeat felony DUI, drug-driving or homicide offender's impounded vehicle may be forfeited and sold. An interdicted license or ID marks someone who may not buy alcohol in Utah restaurants, bars or state liquor stores; a court may order it and collect the license, adding the status costs a $7 fee, the court sets the length, and a person may volunteer for it by renewal or duplicate with an agreement form, keeping it at least 30 days before reapplying for a normal card.
Records and driving while suspended
Displaying a license you know is canceled, suspended or altered, or altering one, can bring suspension. The division keeps a computerized driving and crash record of moving-violation convictions and suspensions for the past three years, while alcohol and drug violations, suspensions and revocations stay 10 years; courts report convictions for posting, and commercial drivers' records go to the national systems. Driving while denied, suspended or revoked can mean 90 days in jail and a fine, and the original period is doubled by being added again; when the original action was alcohol-related the fine may reach $1,000 with up to six months in jail, and driving while suspended for DUI, a drug metabolite, automobile homicide, an alcohol-restriction violation or a refusal can get the vehicle impounded.
Suspensions, revocations and points
The privilege is suspended, for as long as two years or until the 21st birthday, for a conviction requiring mandatory suspension; causing or contributing by reckless or unlawful conduct to a crash with injury, death or serious damage; unlawful or fraudulent use of your license by someone else; enough violations to trigger the point system; a DUI arrest or any drug conviction; failing to appear for a Utah or compact-state traffic citation or to pay fees, fines or restitution on a criminal charge; failing to show no-fault insurance or other security; driving or letting a registered vehicle be driven uninsured; failing to pay child support; a texting conviction with a judge-ordered suspension; using false proof of age under 21 to obtain or drink alcohol or enter a bar; custodial interference; a conviction for improperly approaching an emergency vehicle without completing the four-hour live safety course; and a first road-rage-enhanced citation, which a court may punish with a one-year suspension. Revocation is mandatory on conviction of manslaughter or automobile homicide while driving; a second or later DUI or driving with any measurable controlled substance or metabolite, including prescribed medication; a false statement under oath on a license application; using a vehicle to commit or facilitate a felony; failing to stop and give aid after a crash with death or injury; two reckless or impaired driving charges in one year (a court may recommend three months on the first); fleeing or refusing to stop for an officer's signal; discharging or allowing discharge of a firearm from a vehicle; using any explosive, chemical or incendiary device from a vehicle; driving with any detectable alcohol while alcohol-restricted; driving without a required interlock; a careless driving conviction with a judge-ordered revocation; automobile homicide using a handheld device; refusing chemical testing; and two road-rage-enhanced citations in one year; forfeiting bail counts as a guilty finding. Points: reckless driving 80; speeding 35 to 75 by severity; failure to yield, following too closely, wrong side of the road and wrong way on a one-way 60 each; red light, stop sign, improper lookout, improper passing and texting while driving 50 each; other moving violations 40. Over 21, 200 or more points in three years brings a hearing; under 21, 70 or more; the hearing may bring probation, a defensive driving course, or denial or suspension of one month to one year. Half the points drop after one full year without a moving-violation conviction, all after two successive clean years, and each conviction's points fall off three years after the violation; completing a division-recommended defensive driving course removes 50 points, allowed once in any three-year period, and it is not the same as court traffic school.
