A Denver area school bus driver was arrested after school district officials said they received a report of the man discarding vodka bottles from his school bus. According to a report, the man was taken to the hospital for a random alcohol screening and police were contacted.
The man was arrested for various accusations including suspicion of driving under the influence, reckless endangerment and child abuse after police said he failed to perform voluntary roadside maneuvers adequately. Sometimes voluntary tests that police perform on people who they suspect have been drunk driving only test a person’s coordination, not their ability to drive a vehicle. The outcome of the case was not clear at the time of reporting, but every person who is accused of drunk driving should take the accusation seriously and might be wise to speak with an attorney before speaking with police.
A drunk driving accusation in Denver can result in a person losing their job and having difficulty finding employment in the future. A news report said the man in this case admitted to authorities that he had consumed vodka and cold medicine before driving the school bus.
Many times people will talk to authorities when they feel that telling authorities what they want to hear will help the person’s case. However, many times police and investigators aren’t in a position where they are authorized to negotiate. An attorney can be with a person during questioning and ensure that they don’t answer questions in a way that might incriminate the person.

Why a DUI Charge Hits Commercial Drivers Harder
Cases like this one highlight a reality that goes beyond the criminal courtroom: a commercial driver’s license, or CDL, is governed by a stricter set of rules than a standard driver’s license, and a single DUI arrest can put an entire career at risk. Under federal regulation 49 CFR 383.51, a CDL holder can be disqualified from driving a commercial vehicle for driving under the influence, and that disqualification applies even if the DUI occurred in a personal vehicle rather than a bus or truck.
Colorado sets the legal blood alcohol concentration limit for commercial drivers at 0.04%, half the 0.08% threshold that applies to non-commercial drivers. A CDL holder does not need to reach the standard legal limit to face charges while operating a commercial vehicle, and a conviction, or in some cases an administrative finding, can lead to a one-year disqualification of the CDL for a first offense. A second offense generally results in a lifetime disqualification.
Administrative Consequences Move on Their Own Timeline
As with any DUI arrest in Colorado, the administrative license process runs separately from the criminal case. A person arrested for DUI has seven days from the date of arrest to request a DMV hearing to challenge a license suspension. Missing that window results in an automatic suspension regardless of how the criminal charges are eventually resolved. For a CDL holder, the stakes of that seven-day deadline are higher, since both the standard license and the commercial endorsement can be affected.
We explain how this two-track process works, and what a first-time offender can expect, in our overview of first offense DUI charges in Denver.
Child Abuse and Reckless Endangerment Allegations in Cases Involving Children
When a DUI arrest involves a school bus driver, prosecutors sometimes add related charges, such as reckless endangerment or child abuse, based on the theory that children in the vehicle were placed at risk. These are separate charges from the DUI itself, each with its own elements the prosecution must prove. An arrest on these additional charges is not the same as a conviction, and the specific facts, including what if anything a child experienced, matter enormously to how such a charge is ultimately handled.
What a Statement to Police Can Mean for a Commercial Driver
As this story illustrates, admissions made during a roadside stop or a hospital screening can become central evidence in both the criminal case and any related CDL disqualification proceeding. Because a commercial driver is already facing a lower BAC threshold and harsher administrative consequences, what gets said in the hours after an arrest can carry outsized weight. We discuss how these statements can affect a case in more detail in our article on how background checks factor in after a DUI arrest or conviction, since a CDL disqualification and any related record can follow a commercial driver into future job applications.
Protecting a Commercial Driving Career After a DUI Arrest
If you hold a CDL and are facing a DUI or related charge, the decisions you make in the first several days can affect both your criminal case and your ability to keep driving for a living. Understanding the interaction between the DMV’s administrative process, federal CDL disqualification rules, and any additional charges filed alongside a DUI is central to protecting your livelihood.

Frequently Asked Questions About CDL Drivers and DUI Charges in Colorado
Can I lose my CDL for a DUI in my personal vehicle?
Yes. Federal regulations governing commercial driver’s licenses apply regardless of whether the vehicle involved was a commercial truck or bus or a personal car. A DUI conviction in a personal vehicle can still result in a one-year disqualification of a CDL for a first offense.
What BAC level applies to commercial drivers in Colorado?
Colorado sets the legal blood alcohol concentration limit at 0.04% for commercial drivers operating a commercial vehicle, compared to 0.08% for drivers operating a personal vehicle. This lower threshold means a commercial driver can face charges at a BAC level that would not trigger a standard DUI charge.
How long is a CDL disqualified after a first DUI?
A first DUI-related disqualification of a commercial driver’s license generally lasts one year under federal rules, and can extend to three years if the offense occurred while operating a vehicle placarded for hazardous materials. A second qualifying offense typically results in a lifetime disqualification.
Can additional charges like child endangerment be added to a DUI case involving a bus driver?
Yes. Prosecutors may file additional charges, such as reckless endangerment, when children were present in a vehicle during an alleged DUI. These are separate charges from the DUI itself, and each requires its own proof, so an arrest on these charges is not the same as a conviction.
Should I talk to police before speaking with an attorney if I am a commercial driver?
It is generally advisable to speak with a criminal defense attorney before answering detailed questions from police or making statements during a roadside stop or hospital screening. Statements made in the moment can become evidence in both the criminal case and any related CDL disqualification proceeding.
