Colorado Responsible Vendor Study Guide 2026

What the responsible vendor program is

Colorado's Responsible Alcohol Beverage Vendor Act (C.R.S. 44-3-1001 and following) sets a standard for liquor licensees. To be a responsible vendor, a licensee must follow the server and seller training program set by the director of the Liquor Enforcement Division (LED) of the Colorado Department of Revenue. The details are in Regulation 47-605. Being a responsible vendor is voluntary: the law does not make every server take this training, but sets what a licensee must do if it wants the designation.

When the Division set the program, the law told it to consider input from state and local government, the alcohol industry, and other server and seller programs. The result is one set of rules that every approved trainer follows.

Who attends

All employees who sell or serve alcohol
The owners or managers who directly supervise them
New employees who sell, handle or serve alcohol, within 90 days of hire once the licensee is designated

The class and the knowledge test

Rule	Colorado
Initial class length	At least 2 hours of instruction (surveys and discussion do not count)
Test	Knowledge test; pass with 70% or better
If you cannot read or write English	Verbal test with the same questions
Recertification	Every 2 years, with a 30-day grace period
Format	Classroom, or live streaming with live interaction; no self-paced online courses

Ways to recertify

Pass a recertification test. If you fail the first try, take a course.
Or take a recertification course that covers law changes and refreshes sales to intoxicated persons, sales to minors, legal hours and liability.
Or repeat the full initial program.

Trainers and records

Only trainers on the Division's approved list count. They include police departments, trade groups and private companies. Trainers renew their approval every 2 years and keep attendance and completion records for at least 3 years. Programs may be tailored to on-premises or off-premises businesses.

What approved classes teach

Alcohol's effects on the body, visible intoxication, and drug and medication interactions
Liquor liability: civil, criminal, administrative and management liability
Sales to visibly intoxicated persons, ways to step in, and DUI and DWAI (driving while ability impaired)
Sales to minors
Acceptable ID and spotting false IDs
Other Colorado laws: permitted hours, prohibited purchases, delivery and takeout rules and liquor store tastings
For owners and managers: licensing contacts, recommended policies and record-keeping

Expect the knowledge test to draw from every item on this list. Liability questions are common, so learn the difference between the types: criminal charges come from the state, administrative action is taken against the liquor license, and civil cases are lawsuits for damages.

Responsible service skills

Colorado law sets the rules above. The skills below are taught in every responsible alcohol service class in the U.S., and practice tests 2 and up cover them.

Standard drinks

One U.S. standard drink holds about 14 grams (0.6 fluid ounces) of pure alcohol. That is about 12 oz of regular beer, 5 oz of table wine, or 1.5 oz of 80-proof spirits. A large pour or a mixed drink with several shots can hold two or three standard drinks.

How alcohol affects people

Blood alcohol concentration (BAC) rises faster when people drink quickly or on an empty stomach.
Smaller people, and most women, reach a higher BAC from the same number of drinks.
The liver clears about one standard drink an hour. Coffee, cold showers and fresh air do not speed this up.
BAC can keep rising for a while after the last drink.

Spotting intoxication

Watch for changes in a guest: talking louder, becoming overly friendly, rude or careless, slurring words, slow answers, glassy eyes, stumbling or spilling drinks. Count drinks and talk with co-workers about guests who worry you. If someone seems far more impaired than their drinks explain, think of drink spiking or drugs and get help.

Refusing service

Tell a manager and your co-workers.
Speak to the guest privately, calmly and without judging.
Explain that the law or house policy does not let you serve more alcohol.
Offer water, food or a non-alcoholic drink.
Help the guest get a safe ride home. Call police if an impaired person insists on driving.
Write what happened in the incident log.

Checking ID

The legal age to buy or drink alcohol is 21 in every state. Accept only valid, government-issued photo ID. Compare the photo and description with the person, check the birth date and expiration date, and feel the card for cuts, bumps or peeling. Watch for borrowed, altered and fake IDs. If you are unsure, do not serve.

Emergencies

Confusion, vomiting, seizures, slow or uneven breathing, pale or bluish skin and being hard to wake are signs of alcohol overdose. Call 911, stay with the person, and turn them on their side. Never leave them alone to sleep it off.

Exam tips

Know the numbers: 2 hours, 70% to pass, 90 days for new hires, 2 years between recertifications, 30-day grace period, 3 years of records.
Remember that Colorado uses the term DWAI as well as DUI.
Remember that self-paced online courses do not count.

Training is only part of the picture. Under Colorado's program, a responsible vendor also keeps its training current: new hires are trained on time, recertifications are done every two years, and records show who was trained and when. Treat your own certificate the same way and note its renewal date.
