High-speed crashes are categorically different from other car accidents – not just in severity, but in how they’re investigated, how liability is established, and how quickly critical evidence disappears. If you were injured in a high-speed collision in the Denver metro, the decisions made in the first 72 hours can determine whether your case is provable.
At Boesen Law, we’ve spent decades handling serious car accident injury cases on Colorado’s highways and urban corridors. This page explains what makes high-speed crashes legally distinct, which Denver roads produce them most often, and what you need to know to protect your claim.

Why High-Speed Crashes Are More Legally Complex
The physics are unforgiving. When a vehicle’s speed doubles, the energy released in a collision increases fourfold. But beyond the medical severity, high-speed accidents create legal complications that lower-speed crashes don’t.
4× – Impact force increase when speed doubles
316 ft – Stopping distance at 70 mph (vs. 75 ft at 30 mph)
72 hrs – Window before key evidence begins to disappear
3+ – Liable parties typical in complex speed-related crashes
Higher speeds mean multiple liable parties are more likely – the driver, sometimes the employer if it was a commercial vehicle, road agencies if conditions were defective, and occasionally a vehicle manufacturer if equipment failure contributed. Each additional party means a separate insurance policy, separate legal team, and a more complex negotiation.
From the attorneys at Boesen Law
In our experience, high-speed accident cases are won or lost on physical evidence that’s gone within days. Skid marks fade or are washed away. Debris is cleared. Black box data from modern vehicles – which records speed, braking, and steering inputs in the seconds before impact – can be overwritten within 30 days of a crash unless a preservation letter is sent immediately.
This is why we ask clients to call us before they’ve had a chance to process what happened. Not because we’re in a hurry for their business, but because their case literally expires if we wait.

Denver’s High-Speed Crash Hotspots
Colorado State Patrol data consistently identifies the same corridors where speed-related fatalities and serious injuries cluster in the Denver metro. If your crash happened on one of these roads, it’s a detail that matters for your case – both in establishing the crash dynamics and in identifying whether road conditions or signage contributed.
I-70 (Denver to Aurora)
High volume at speed, construction zones, merge conflicts. Speeding fatalities spike near the Mousetrap interchange and east of I-225.
I-25 (C-470 to downtown)
The most congested corridor in Colorado. Speed variance – not uniform high speed – drives many serious crashes here.
C-470 / E-470
70 mph limit, wide lanes, and less congestion create conditions where speeding often goes unchecked until something goes wrong.
US-36 (Boulder Turnpike)
Express lane transitions and late merge behavior at high speeds create complex liability situations involving multiple vehicles.
Colfax Ave & Quebec St
Urban drag racing and street racing complaints have increased in these corridors. Witnesses are more common – but so is disputed fault.
US-285 (Southwest Denver)
Mountain highway geometry with front-range traffic volumes. Limited guardrails in certain segments increase rollover and ejection risk.
Establishing Fault: What We Investigate
Fault in a high-speed crash is rarely self-evident – and the at-fault party’s insurer will work hard to minimize or dispute it. Our investigation typically runs on several tracks simultaneously.
The vehicle’s electronic data
Every vehicle manufactured after 2012 contains an Event Data Recorder – colloquially called a black box. In the 5–10 seconds before impact, it logs speed, throttle position, brake application, seatbelt status, and airbag deployment. This data is legally recoverable but time-sensitive. We send preservation demands to opposing parties and, when necessary, seek emergency court orders to prevent data from being erased or the vehicle from being crushed.
Driver conduct
We gather police reports, witness statements, traffic camera footage (CDOT maintains cameras across the metro), and prior driving records. If impairment or distracted driving is suspected, we work with toxicology experts and phone record subpoenas. In commercial vehicle cases, Hours of Service logs and dispatch records are a priority.
Road and infrastructure conditions
Government entities – CDOT, the City of Denver, or county agencies – can be liable when road conditions contribute to a crash. This might include inadequate signage in a construction zone, a pothole that caused loss of control, or lighting failures at a known high-risk interchange. Claims against government entities in Colorado require a Notice of Claim filed within 182 days of the accident – a deadline most injury victims don’t know exists.
Real-world scenario
A driver merges into your lane at highway speed without signaling. You brake hard but are rear-ended by a third vehicle that was following too closely. The at-fault merger has minimum insurance. The rear vehicle’s driver claims you braked “without warning.”
This scenario – two potentially liable parties, disputed fault, and minimum policy limits – is more common than you’d think on I-25. EDR data from all three vehicles, combined with CDOT camera footage, is what unravels cases like this. Without an attorney who moves quickly, the footage is deleted on a rolling 30-day cycle.
Evidence That Disappears – and When
Speed-related crash investigations are time-critical in ways that ordinary fender-benders are not. Here’s the evidence we prioritize and why the clock matters:
| Evidence Type | Preservation Window | Why It Matters |
| CDOT / traffic camera footage | 7–30 days | Overwritten on a rolling cycle. Often captures the actual crash or pre-crash speeding behavior. |
| EDR / black box data | ~30 days | Overwritten by subsequent events. Vehicle may be sold, repaired, or scrapped. |
| Skid marks and debris | Days to 2 weeks | Rain, street cleaning, and traffic obliterate physical crash evidence quickly. |
| Witness memory | Weeks | Eyewitness accuracy degrades rapidly; early recorded statements are far more reliable. |
| Commercial driver logs | 6 months (federal law) | Hours of Service violations and dispatch records can establish carrier liability. |
| Notice of Claim (govt. entity) | 182 days | Colorado law bars government-entity claims if notice isn’t filed within this window. |
What You’re Entitled to Recover
High-speed crashes tend to produce severe injuries – spinal cord damage, traumatic brain injury, shattered limbs, burns – with long recovery arcs or permanent impairment. Our job is to make sure the compensation reflects the full scope of what was taken from you, not just the immediate bills.
Recoverable damages typically include:
- Current and future medical expenses – including surgeries, rehabilitation, assistive devices, and in-home care
- Lost wages and diminished earning capacity – calculated not just as missed paychecks, but as the difference between what you could earn before and after the injury, projected over your working life
- Pain and suffering – chronic pain, lost mobility, and psychological impact are compensable; we document them carefully
- Property damage – vehicle replacement or repair, plus the diminished value of a repaired vehicle that is now accident-flagged on Carfax
- Wrongful death damages – if a family member was killed, surviving spouses and dependents may recover for loss of companionship, support, and future income
Don’t accept an early settlement offer
Insurance adjusters sometimes reach out within days of a serious crash with a settlement offer. It feels fast and considerate. It isn’t. The offer is made before your full injuries are known, before imaging has revealed internal damage, and before anyone has calculated your long-term losses. Accepting it closes your claim permanently. Call us before you respond to any offer.
What to Do After a High-Speed Accident in Denver
- Call 911 and stay at the scene. A police report is non-negotiable in a high-speed crash. It documents the other driver’s speed, behavior, and any citations issued – all of which become evidence.
- Seek emergency medical care immediately – even if you feel okay. Adrenaline masks pain. Traumatic brain injuries, internal bleeding, and spinal injuries often don’t present symptoms for hours or days. A gap between the crash and your first medical visit is the first thing insurers will use against you.
- Photograph everything before anything is moved. Vehicle positions, skid marks, road conditions, traffic signals, debris field, your visible injuries. The scene will be cleared within hours.
- Get witness information. Names and phone numbers of anyone who saw the crash, including bystanders who stopped. Do not rely on the police report alone – witnesses are sometimes omitted.
- Do not give a recorded statement to any insurer. Not the other driver’s insurer, and not your own. You are not legally required to do so before speaking with an attorney. These statements are used to minimize your claim.
- Contact Boesen Law before the evidence window closes. We send preservation demands and initiate our investigation within hours of being retained. The sooner we’re involved, the more evidence we can save.
Colorado’s Statute of Limitations: Three Years, Not Infinite
Colorado law gives you three years from the date of the crash to file a personal injury lawsuit. That sounds generous, but building a strong case – gathering EDR data, retaining accident reconstruction experts, obtaining all medical records, calculating long-term economic losses – takes time. Clients who come to us two years after their crash often face a compressed, more difficult case than those who come early.
If a government entity is involved (a defective road, broken signal, or failure by a public agency), the 182-day Notice of Claim deadline applies on top of the three-year statute. Missing it extinguishes the claim entirely.
What makes these cases hard to win without an attorney
Insurance companies that cover high-speed accident claims are sophisticated. They retain their own accident reconstructionists, medical reviewers, and defense attorneys from day one. Their goal is to dispute speed, dispute fault, or dispute the connection between the crash and your injuries. We counter that with our own experts, preserved physical evidence, and – when necessary – trial.
We’ve handled enough of these cases to know which arguments insurers will make and how to undercut them. That knowledge only comes from years of doing this work in Colorado courts.
