I. Alcohol Minimum Ages

Young people in Wyoming often want to work in hospitality. They want to know the ages needed for jobs working around alcohol. How young can a server be in a restaurant selling alcohol for drinking on-site?

Does a person have to be older to tend bar? What about for working in a store selling alcohol for drinking off-site?

Wyoming alcohol laws permit adults to serve alcohol in venues for drinking there. That is, the minimum age is 18. For tending bar and selling alcohol in venues for drinking elsewhere, the age is 21.

Note that Wyoming counties and cities can modify the above ages and restrictions. So it’s important to check locally.

Persons of any age under 21 may legally drink alcohol if a member of the “immediate family” is present. And they may do so in both private and public locations.

Many parents do this to demystefy alcohol and promote moderation. They believe it’s better for youth to learn in the parents’ house than in a frat house.

Use of a false ID to obtain alcohol by anyone under 21 is a crime.

It is also illegal for anyone of under 21 to drive with a blood alcohol concentration (BAC) higher than 0.02%.

II. Other Wyoming Alcohol Laws

A. Selling Alcohol

wyoming alcohol lawsWyoming has a government alcohol monopoly over selling wine and spirits for use off-premises. That means poorer selection and higher prices.

Package stores, bars, and restaurants may sell or serve alcohol any day of the week. And they may do so between 6:00 a.m. and 2:00 a.m. That’s state law. But towns can be more restrictive. They often are for Sunday sales.

It’s a violation of Wyoming Alcohol laws to sell alcohol to anyone under the age of 21. That includes adults under that age.

B. Buying Alcohol

It’s illegal for anyone under age 21 to buy, or attempt to buy, alcohol. But they may do so to help police entrap sellers.

Parents may buy alcohol in restaurants, bars and other places serving alcohol for their offspring to drink with them.

It’s also legal in Wyoming to remove a partially consumed bottle of wine from a restaurant, bar, etc. This law helps prevent over-drinking so as not to “waste” the wine. Thus, it promotes traffic safety.

The penalty for destroying the label on a beer keg is a fine of up to $500.

C. Driving and Alcohol

Wyoming alcohol laws prohibit driving with a blood alcohol concentration (BAC) of 0.08% or higher. For those under 21, it’s 0.02% or higher.

The exact penalties depend on the circumstances and the judge.

The penalty for a first DUI conviction can be driver license suspension for 90 days. For a second, it can be one year. And for a third, three years.

With a third conviction, the driver must take an alcohol abuse course. The judge can also require alcohol assessment and treatment. The judge can order an ignition interlock device (IID) on the offender’s car. Of course, the offender must pay for this expensive device. And its installation, maintenance, and monitoring.

Wyoming alcohol laws do not increase penalties for driving with BAC levels far above the maximum legal limit.

The state prohibits possession of an open alcohol container by anyone of any age in a motor vehicle. But there’s no law against open containers that are not in a vehicle. That is, elsewhere. For example, in a park, sidewalk, etc.

Driver Rights

All drivers have a US Constitutional right to decline a breath tester test. But the state punishes drivers who use their right. The penalty for refusing can include driver license suspension for up to one year.

For example, about one-third of completely sober volunteers fail to pass a field sobriety test. That is, about one of every three people with a zero BAC (0.00%) fail it! And they fail it under ideal conditions indoors.

For drivers pulled over, it’s under terrible conditions. It’s usually at night with police car’s flashing lights. They aren’t volunteers. They’re nervous and fear arrest and spending time in jail. It’s very hard to concentrate. So passing the field tests are hard. And every mistake counts against them.

Lawyers’ Advice

For that reason, lawyers strongly urge drivers never, ever take a field sobriety test. They say to politely decline. And to do so as often as necessary.

But that may take strong willpower. That’s because police have clever ways to get drivers to take them. They often falsely say that the law requires it. That’s simply not true. In fact, no law in any U.S. state requires it.

Sometimes police say you can prove you’re not impaired by passing the test. But you don’t need to prove your innocence. To the contrary, the state must prove that you’re guilty! In addition, police don’t consider passing a field sobriety test to prove innocence!

While investigating, police can legally lie to you. No matter what they say, they’re looking for evidence to arrest you. In reality, they’re opponents at that point. So don’ be a sucker.

D. Boating

Boaters are intoxicated if their BAC is 0.10 or higher within three hours after operating a vessel. Or if alcohol and/or drugs make them unable to operate a watercraft safely.

The state punishes boaters guilty of BUI. It does so by fining them up to $750.00 and/or jailing them for up to six months. It may also suspend their boating license for up to two years.
