On July 15, Governor Snyder signed bills that will allow passengers to consume alcohol while riding "commercial quadricycles" also known as pedal pubs.
The law allows passengers to have "beer, wine, spirits, or a mixed spirits drink" in an open container. The bill signed by the governor doesn't define what spirits are. Some news websites have stated that the law does not allow "hard liquor" consumption. Hard liquor is not a term used in the law.
Spirits are defined in the Liquor Control Code as distilled alcohol mixed with water or other substances. What people may not realize is that the whiskey, gin, or vodka you buy in a store has actually been diluted with water. So, when people think of hard liquor, they are talking about spirits, and spirits can be consumed on these pedal pubs.
An important note: this law allows local ordinances to over-ride it, so even though it is legal in the state, it may not be legal in your particular location.
Another note: just because it may be legal, it doesn't mean that the owner or operator of the pedal pub has to allow you to drink. You're still making a contract with the pedal pub operator, and it is their choice to decide what passengers are allowed to do.
The operator of the pedal pub must have a 0.00 blood alcohol level (BAC). Note that the operator is the person steering. The passengers peddling the pub are not operators. The law sets a fine of $300 for the driver for a BAC up to 0.04. According to this website, that is about one drink for the average person. Anything over 0.04 can mean a stay in jail up to 93 days, on top of the fine.
If a pedal pub is involved in any kind of accident, you can be sure that the driver will be tested for alcohol. A zero-tolerance limit for alcohol means that even one drink consumed hours before starting work could lead to a violation of the law for the driver.
The owner of a pedal pub is required to carry "bodily injury and property damage liability insurance with a minimum combined single limit of $2,000,000.00 for all persons injured or for property damage." This affects all pedal pub owners, even if they don't want to allow consumption of alcohol by patrons.
I expect that many cities will soon be passing their own regulations regarding these pedal pubs, and what can be consumed, and when, and how.
What this all means is that if you are a pedal pub owner who wants to allow drinking, you will need to do a bit of work before. Insurance, liability waivers and contracts for passengers, training and testing for drivers, and local ordinances will all need to be looked at to make sure you're in the clear.
