A Colorado DUI crash can become much more serious when another person suffers serious bodily injury. A case that might otherwise involve a misdemeanor DUI or DWAI allegation may lead to a felony vehicular assault charge. You could face prison, fines, restitution, driver’s license consequences, treatment requirements, and a felony record.
Summer traffic can add more facts for police, prosecutors, and defense attorneys to examine. Construction zones, motorcycles, bicycles, pedestrians, event traffic, mountain travel, glare, storms, and congested roads may all affect how a collision happens. The investigation may include crash reconstruction, toxicology, witness statements, video, vehicle data, and medical records.
Hebets & McCallin P.C. helps people understand what the prosecution must prove, what evidence may be challenged, and what defense options may apply.
A summer crash does not create a separate DUI offense. The injury, causation, and evidence can change the case from a misdemeanor investigation into a felony prosecution.
Why an Injury Changes a Colorado DUI Case 
A standard DUI case usually focuses on whether you drove while under the influence of alcohol, drugs, or both. A DWAI case generally focuses on whether alcohol, drugs, or both affected you to the slightest degree so that you were less able than usual to drive safely.
When a crash causes serious bodily injury, prosecutors may consider vehicular assault under C.R.S. 18-3-205. DUI-based vehicular assault is generally a class 4 felony.
This change matters because a felony case can expose you to consequences that are more severe than those associated with most first-time misdemeanor DUI cases. Possible consequences include incarceration, substantial fines, restitution, driver’s license action, treatment, employment problems, professional licensing concerns, immigration consequences for some noncitizens, and a lasting felony record.
An injury does not automatically prove vehicular assault. The prosecution still must prove every required element beyond a reasonable doubt, including the applicable impairment allegation, serious bodily injury, and a legally sufficient causal connection between the driving and the injury.
What Counts as Serious Bodily Injury?
Not every bruise, cut, or complaint of pain qualifies as serious bodily injury under Colorado criminal law. The statutory definition generally includes an injury that creates or involves:
- A substantial risk of death
- A substantial risk of serious permanent disfigurement
- A substantial risk of protracted loss or impairment of the function of a body part or organ
- A break or fracture
- A penetrating gunshot wound
- A penetrating knife wound
- Second- or third-degree burns
This definition can include an injury that does not appear life-threatening at the crash scene. A broken wrist, fractured rib, or injury requiring surgery may support a serious bodily injury allegation.
Medical records, diagnostic imaging, physician opinions, treatment notes, and recovery information may become central evidence. The defense may review whether the medical evidence supports the statutory definition and whether the alleged injury resulted from the charged conduct.
The timing can also matter. You may leave the scene believing that everyone is safe, then learn that another driver, passenger, cyclist, or pedestrian was later diagnosed with a fracture or another qualifying injury. Police and prosecutors may then treat the case as a potential felony.
Just like anything else, practice leads to proficiency. With over 35 years of combined experience, we've gathered extensive knowledge inside and outside the courtroom.
Potential Penalties for DUI Vehicular Assault
DUI vehicular assault is generally a class 4 felony in Colorado. A class 4 felony can carry a presumptive prison range of two to six years and a presumptive fine range of $2,000 to $500,000. Sentencing depends on the charge, criminal history, aggravating or mitigating facts, applicable statutes, and the court’s findings.
Other possible consequences include:
- Restitution for medical expenses, lost income, property damage, and other legally recoverable losses
- Driver’s license revocation or other action by the Colorado Division of Motor Vehicles
- Alcohol or drug evaluation, education, monitoring, or treatment
- Probation or community corrections when legally available
- Parole requirements following a prison sentence when required by law
- Employment and professional licensing problems
- Immigration consequences for some noncitizens
- Increased insurance costs
- Housing, education, and financial consequences associated with a felony record
You may also face separate traffic charges, including careless driving, reckless driving, speeding, or lane violations. If more than one person suffered serious bodily injury, prosecutors may file more than one count.
The possible sentence in any case depends on the facts and current Colorado law. A general penalty range is not a prediction of the sentence you may receive.

Why Summer Crashes Can Be More Complicated
Summer does not create a separate DUI penalty. Seasonal road conditions and travel patterns can still affect how a crash happened and how the case is investigated.
Denver and nearby Colorado communities may experience event traffic, vacation travel, mountain trips, concerts, baseball games, road construction, and holiday traffic. Drivers may share the road with more motorcycles, bicycles, pedestrians, rideshare vehicles, and out-of-state visitors.
Summer conditions may also include:
- Construction zones and lane shifts
- Sun glare and reduced visibility
- Sudden afternoon storms
- Wet pavement
- Heavy highway congestion
- Crowded event parking areas
- More motorcycles, bicycles, and pedestrians
- Multiple vehicles involved in a chain-reaction collision
These facts can matter because causation is a required part of a vehicular assault case. The prosecution must prove that the accused person drove while under the influence or while ability was impaired and that the driving was the proximate cause of serious bodily injury.
A crash may involve more than one contributing factor. Another driver may have changed lanes suddenly, stopped without warning, entered traffic unexpectedly, or violated a traffic control device. Road design, construction, mechanical failure, weather, visibility, or an unexpected pedestrian or cyclist movement may also require close review.
These facts do not automatically defeat a DUI allegation. They may affect whether the prosecution can prove the required causal connection.
How Police Build an Injury-Related DUI Case
An injury crash usually leads to a more detailed investigation than a routine traffic stop. Officers may close lanes, photograph the scene, measure distances, inspect vehicles, interview witnesses, and request chemical testing.
Evidence may include:
- Body-camera and dash-camera footage
- 911 calls and dispatch recordings
- Crash-scene photographs and measurements
- Vehicle damage
- Event data recorder information
- Skid marks, debris, road design, signs, and traffic controls
- Statements from drivers, passengers, and witnesses
- Hospital records and medical opinions
- Blood or breath test results
- Receipts, phone records, and location data obtained through lawful process
- Crash reconstruction opinions
- Toxicology opinions
- Surveillance or traffic-camera footage
Pain, shock, head injuries, prescribed medication, dehydration, and emotional distress can affect speech, balance, memory, coordination, and appearance. Police may interpret some of those symptoms as signs of intoxication.
A careful defense review should compare the officer’s observations with medical records, video, witness statements, and the physical evidence. It should also examine whether testing was performed lawfully and whether the results are scientifically reliable.
The Difference Between DUI, DWAI, and Vehicular Assault
Colorado distinguishes DUI from DWAI.
DUI generally means that alcohol, drugs, or both made a person substantially incapable of safely operating a motor vehicle. DWAI generally means that alcohol, drugs, or both affected a person to the slightest degree so that the person was less able than usual to drive safely.
A serious-injury crash can lead to several possible charges. Vehicular assault may be based on DUI, DWAI, or reckless driving, depending on the allegations and evidence. The required proof, classification, and possible penalties may differ.

Felony DUI and DUI-based vehicular assault are separate charges. Felony DUI commonly concerns qualifying prior convictions. Vehicular assault concerns serious bodily injury allegedly caused by driving under the influence, driving while ability was impaired, or reckless driving.
What the Prosecution Must Prove
The exact elements depend on the charge filed. In a DUI-based vehicular assault case, the prosecution generally must prove that:
- You operated or drove a motor vehicle.
- You were under the influence of alcohol, drugs, or both.
- Another person suffered serious bodily injury.
- Your driving was the proximate cause of that serious bodily injury.
A DWAI-based or reckless-driving theory may require a different analysis.
Causation can be disputed. A collision may involve another driver’s sudden maneuver, a mechanical problem, poor road design, construction, weather, an unexpected pedestrian movement, or several contributing acts.
The defense may examine whether the injury would have occurred in the same way without the accused person’s conduct, whether an intervening event affected the outcome, and whether the physical evidence supports the prosecution’s reconstruction.
Defense Strategies in a DUI Injury Case
No single defense applies to every case. A defense attorney may review several issues at the same time.
Possible areas of review include:
- Whether police had lawful grounds for the stop, detention, arrest, or blood draw
- Whether you were driving or in actual physical control of the vehicle
- Whether injuries, shock, fatigue, or medication were mistaken for signs of impairment
- Whether the blood or breath result is accurate and admissible
- Whether the sample was collected, stored, transported, and tested correctly
- Whether a medical condition affected the chemical test or officer observations
- Whether the alleged injury meets the legal definition of serious bodily injury
- Whether another driver, road condition, weather event, or mechanical problem caused or contributed to the crash
- Whether witness accounts match the video and physical evidence
- Whether crash reconstruction methods and assumptions are reliable
- Whether statements were obtained in violation of constitutional rights
- Whether officers preserved all relevant evidence

What to Do After a Summer DUI Crash With Injuries
The hours after a serious crash can be confusing. You may be injured, worried about another person, and unsure about what police are asking.
Consider these steps:
- Get necessary medical treatment.
- Do not discuss fault, alcohol, drugs, or the crash on social media.
- Preserve the citation, bond paperwork, DMV notice, hospital documents, and discharge instructions.
- Write down the route, timeline, weather, traffic, road conditions, and events you remember.
- Save photographs, receipts, parking records, event tickets, text messages, and location history.
- Identify possible witnesses and preserve their contact information.
- Do not repair, sell, or dispose of the vehicle before receiving legal guidance.
- Do not contact an injured person to discuss fault, payment, or the criminal case without legal advice.
- Do not make additional statements to police or an insurance company before understanding your rights.
- Speak with a Colorado DUI defense attorney as soon as possible.
A DMV matter can move on a different schedule from the criminal case. Missing a deadline may affect your driving privileges while the criminal case remains pending.
