A police crash report can make a serious collision look settled before the defense has examined the evidence. It may assign fault, estimate speed, describe the point of impact, and frame the driver’s conduct as reckless or impaired. In a Denver vehicular assault case, those early conclusions can influence charging decisions, plea negotiations, and how prosecutors present the case.

The problem is that a police report is not proof. Officers often prepare crash reports based on witness statements, final vehicle positions, visible damage, skid marks, body camera footage, and observations made in a chaotic scene. Those details matter, but they can also contain assumptions.

At the Law Office of Jacob Martinez, our Denver criminal defense lawyers approach a vehicular assault case by testing the report against the physical evidence. When 3D scene reconstruction, crash data, vehicle damage, road conditions, or medical evidence do not match the officer’s narrative, the defense can expose those gaps and challenge the prosecution’s theory of causation.

What a Vehicular Assault Charge Requires in Colorado

A vehicular assault charge in Colorado requires the prosecution to prove that a driver caused serious bodily injury to another person. Under C.R.S. § 18-3-205, Colorado’s vehicular assault law generally follows two main paths.

The first path involves reckless driving. Prosecutors may allege vehicular assault when a person operates or drives a motor vehicle in a reckless manner and that conduct is the proximate cause of serious bodily injury to another person.

The second path involves alcohol or drugs. Prosecutors may allege vehicular assault when a person operates or drives a motor vehicle while under the influence of alcohol, drugs, or both, and that conduct is the proximate cause of serious bodily injury to another person. This DUI-related version is treated differently because the statute makes it a strict liability offense.

Strict liability matters. In a DUI-based vehicular assault case, the prosecution may not have to prove the same reckless mental state required in a reckless-driving theory. The defense may therefore focus heavily on whether the client was actually impaired, whether the testing was reliable, whether the driving caused the injury, and whether another factor broke the causation chain.

The phrase serious bodily injury also has a specific legal meaning. In Colorado, serious bodily injury generally involves harm such as a substantial risk of death, serious permanent disfigurement, or protracted loss or impairment of a body part or organ. That legal definition shapes the defense because evidence of medical records, diagnosis, mechanism of injury, and causation may all matter.

Charges Often Filed With Denver Vehicular Assault

Serious crashes rarely arrive as a single criminal count. One collision can produce several overlapping charges, especially when prosecutors believe reckless driving, impairment, serious injury, or flight from the scene may be involved.

Common companion charges may include:

• Vehicular assault for serious bodily injury allegedly caused by reckless or impaired driving.
• Vehicular homicide if the crash resulted in death.
• DUI, DWAI, or drug-related impaired driving charges.
• Reckless driving or careless driving.
• Leaving the scene of an accident or hit-and-run.
• Traffic offenses based on speed, lane use, right of way, or failure to obey a traffic control device.

These charges may look separate on paper, but they often depend on the same factual foundation: what happened, who caused it, how the vehicles moved, and whether the state can prove the required legal connection between the driving conduct and the injury. A strong defense should build one consistent factual account across every count, not respond to each charge in isolation.

Where a Denver Crash Report Can Be Wrong

A police report can be inaccurate or incomplete because it is usually prepared after the collision has occurred. Officers may arrive at a scene with damaged vehicles, injured people, blocked traffic, emotional witnesses, emergency responders, and limited time to preserve evidence.

That does not mean the report is dishonest. It means the report may be a first draft built from incomplete information.

Speed estimates are a common problem. A calculation based on skid marks, crush damage, roadway friction, or final rest positions can change if the underlying assumptions are wrong. A mistaken coefficient of friction, a missed pre-impact braking mark, a wrong impact angle, or an incorrect point of impact can significantly alter the speed estimate.

Witness statements can also be unreliable. A person may have seen only part of the collision, misunderstood which vehicle entered the intersection first, or filled in gaps after the crash. Stress, noise, distance, lighting, intoxication, weather, and memory can all affect what a witness believes they saw.

Scene diagrams can create problems too. A diagram may be based on an officer’s vantage point rather than precise measurements. If lane positions, debris fields, gouge marks, sight lines, signal timing, or roadway grade are not accurately documented, the report may tell a story that the physical evidence does not support.

Because speed, impairment, and causation often decide whether prosecutors pursue a felony vehicular assault charge, even a small error can have major consequences.

How 3D Scene Reconstruction Challenges the Police Report

Independent crash reconstruction can replace assumptions with measurements. A reconstruction analyst or forensic engineer may use scene measurements, photographs, laser scanning, drone imagery, vehicle inspections, crush analysis, roadway evidence, and event data recorder information to rebuild the collision from the physical evidence.

3D scene reconstruction can help answer questions such as:

• Where did the impact occur?
• How fast were the vehicles likely traveling?
• Did the driver have time and distance to react?
• Were roadway conditions, visibility, or signal timing relevant?
• Does the damage pattern match the officer’s theory?
• Did another driver, pedestrian, cyclist, or outside factor contribute to the crash?
• Was the alleged injury caused by the accused driver’s conduct or by something else?

This evidence can be especially important in a Colorado vehicular assault case because the prosecution must prove causation. It is not enough to show that a serious crash happened. The state must connect the accused person’s driving to the serious bodily injury charged.

If reconstruction evidence shows that the police report overstates speed, misidentifies the point of impact, ignores another vehicle’s movement, or assumes reaction time that was not physically possible, the defense may have a stronger basis to challenge the charge.

Why 3D Reconstruction Matters in a Vehicular Assault Defense

The value of 3D reconstruction is not that it automatically proves the defense right. Its value lies in the fact that it forces the state’s theory to confront the physical evidence.

In some cases, reconstruction may show that the accused driver was not traveling as fast as the report suggests. In others, it may show that another vehicle violated the right of way, that the client had no reasonable opportunity to avoid the crash, or that the serious injury cannot be tied to the prosecution’s version of events.

That matters because vehicular assault cases often turn on proximate cause. If the defense can show that the alleged reckless or impaired driving was not the legal cause of the serious bodily injury, the prosecution’s case may weaken substantially.

Reconstruction can also affect negotiations. A credible defense analysis may support a reduction in charges, a more favorable plea offer, dismissal of certain counts, or a stronger trial position. The earlier the defense identifies these issues, the more opportunities there may be to use them strategically.

How Accident Reconstruction Evidence Shapes the Defense Strategy

Accident reconstruction findings do more than contradict a number in a report. They help shape the entire defense strategy.

A Denver criminal defense attorney may compare the reconstruction evidence with toxicology results, blood or breath testing, body camera footage, 911 calls, witness statements, traffic camera footage, dash camera footage, medical records, and vehicle data. The goal is to find where the state’s story holds up and where it breaks down.

If impairment is alleged, the defense may examine whether the toxicology evidence actually supports impairment at the time of driving. If reckless driving is alleged, the defense may examine whether the driving conduct meets the legal standard or whether prosecutors are using the seriousness of the injury to infer recklessness after the fact.

If causation is disputed, reconstruction evidence can become central. A person can be involved in a crash without being the legal cause of the serious bodily injury charged. That distinction can be critical in vehicular assault defense.

This is why police reports should be treated as evidence to be tested, not as the final version of events.

Let a Denver Criminal Defense Lawyer Test the Police Report

If you are facing vehicular assault, vehicular homicide, DUI-related injury charges, reckless driving allegations, or another driving-related felony in Denver, the police report should not be accepted without independent review. The physical evidence may tell a different story than the first narrative written at the scene.

At the Law Office of Jacob Martinez, our criminal defense team reviews the facts underlying the report, including speed estimates, crash dynamics, causation, evidence of impairment, witness reliability, medical records, and whether reconstruction evidence may help challenge the prosecution’s case.

A Denver vehicular assault charge can threaten your freedom, driving privileges, reputation, and future. Early defense work matters because crash evidence can disappear, memories can change, and the prosecution’s theory can harden quickly.
