I. DWUI in Wyoming

It’s illegal to drive while under the influence of alcohol or drugs. This is called DWUI in Wyoming.

For drivers age 21 or older, DWUI is driving with a blood alcohol concentration of 0.08% or higher. It’s 0.05% with supporting evidence of being under the influence. For commercial drivers, it’s 0.04%. And for drivers under 21, including adults 18 through 20, it’s 0.02%.

dwui in wyomingWyoming has a zero tolerance policy against drinking by those under 21. But it permits BACs under 0.02%. This is to reduce the chances of convicting innocent young drivers.

Here’s the logic. “Breathalyzers” or alcohol breath testers are unreliable. They don’t really measure BAC. (That requires analysis of a sample of actual blood.) The breathalyzers only estimate it. That’s why not all states permit them.

Another problem is that everyone produces alcohol naturally within their bodies. And they do this 24/7. Obviously, that includes all young drivers. Also, many medications and foods contain alcohol. Surprisingly, this includes baked goods such as bread.

So permitting BACs under 0.02% is good government policy. It helps protect the innocent.

II. Penalties

The exact penalties imposed for DWUI in Wyoming vary. Many factors cause these differences. They include such things as these.

    Please, no! Not her!

    Driver’s Age.

  • Type of license.
  • Estimated BAC.
  • The impairing substance(s)
  • Any prior DUIs.
  • Consequences of the DUI, if any (property damage, injuries, etc.)
  • Any minors in the vehicle.
  • Skill of driver’s attorney.
  • Characteristics of driver (demeanor in court, race, socio-economic status, etc.)
  • Beliefs and personality of judge hearing the case. That’s just the luck of the draw.

Some penalties are mandated, others are within ranges, and others are purely up to the judge.

Ignition Interlock Device

One penalty sometimes used is requiring the use of an ignition interlock device (IID). The device (really a complex system) includes an alcohol breath tester. It prevents a vehicle’s engine from starting if alcohol is on the driver’s breath. Offenders must pay the high expense of having the IID installed, maintained, and monitored.

III. The Costs

Legal Defense

Getting charged with an DWUI in Wyoming is expensive. And this is true even if you’re innocent. Of course, it’s even more expensive if a judge or jury convicts you.

The cost of a legal DWUI defense is very hard to estimate. That’s because the complexity of cases varies widely. And more complex cases take more of a lawyer’s time. That means more money.

dwui in wyomingIt’s wise to select an experienced lawyer who specializes in DUI defense. The knowledge and experience of such a lawyer is invaluable. In fact, such a lawyer may take less time.

Its obvious that simply asking lawyers how much they charge per hour isn’t helpful. It’s like asking a car dealer how much it costs to buy a car.

Other Costs

There are a number of other costs. They may include fines, court costs, property damage, medical expenses, possible loss of employment, increased insurance rates, and other expenses. The total can be high. It can easily be more than lawyer fees and expenses. Therefore, the total cost of an DWUI can easily be tens of thousands of dollars.

In addition, there are non-money costs as well. They may include pain and suffering, feelings of guilt, embarrassment, driving license suspension, loss of friendships, and many others.

Knowing the high costs of a DWUI is very useful. It’s a great motivation. That can help us try to avoid getting one.

IV. Sobriety Tests

Chemical Tests

dwui in wyomingAll states require drivers to submit to alcohol breath tests (estimators). That, in spite of their scientifically proven unreliability.

However, all drivers have a Constitutional right to decline taking a chemical BAC test. In spite of that, the state punishes those who use their right. The first use of the right leads to driving license suspension for six months. Use of the right on a second occasion triggers a suspension for 18 months.

Field Sobriety Tests

However, no state requires drivers to take a field sobriety test. And that’s good. Simply put, field sobriety tests lack validity. That’s why about one-third of completely sober people with a 0.00% BAC fail them. And they do so under ideal conditions.

Naturally, taking a field sobriety test on an uneven highway shoulder after being pulled over by police and being very nervous is far from ideal. So the “real world” failure rate for completely sober people must be much higher.

dwui in wyomingUnderstandably, lawyers strongly urge drivers never to submit to any field sobriety test. On the other hand, police want suspects to take them. They often falsely insist the law requires it. It doesn’t. Or they say that passing it proves you’re innocent. It doesn’t.

An officer who pulls over a driver for suspected drinking and driving is conducting a criminal investigation. The officer may legally lie to you. Remember that if you are a suspect in a crime, the police officer is your adversary.

V. Avoid Arrest

Obviously, one way to avoid a DWUI is by abstaining from alcohol. Another choice is to use a Designated Driver or use public transportation.

Most drivers enjoy drinking alcohol, at least on occasion. They may lack a Designated Driver or access to public transportation. And they may be unable to afford Uber or Lynks.

So how can drivers drink before driving, yet avoid arrest? The answer is simple and legal. Maintain a low BAC.

These guidelines can help keep a low BAC.

    Standard Drinks

    Remember that standard drinks of beer, wine and spirits have equivalent amounts of pure alcohol.

  • Have no more than one standard drink each hour. Preferably less.
  • Avoid non-standard drinks. This makes it easier to keep track of alcohol intake.
  • Eat and snack while drinking. This is very important!
  • Have a non-alcoholic drink between alcoholic ones.
  • Accept an alcoholic drink only when it fits your consumption schedule.
  • Never engage in any drinking game.
  • Don’t try to “keep up” with the drinking of others.
