Nothing up front, and no fee unless there is a recovery. Here is the typical Colorado percentage range, what the law requires the fee agreement to say, why costs are a separate question, and what to ask before you sign.
Yes, but a brain injury trial is a science case. Here is what it takes to prove an injury the jury cannot see: the experts, the advanced imaging, the defense playbook, and the questions to ask any attorney before you hire them.
Yes, a Colorado bike accident attorney can negotiate with insurers and take your case to trial, but your fee agreement has to say so. Here is what to check before you sign, plus five questions to ask any attorney you are considering.
Colorado's 50 percent bar means a cyclist found half at fault recovers nothing. Here is how the math works, why insurers push blame onto riders, and the legal answer to each of the five common blame arguments.
To win a bike crash claim in Colorado you have to prove the driver broke the law, that it caused the crash, and that the crash caused your injuries. Most of that evidence disappears within days. Here is what to collect, where to find it, and what to do in the first 48 hours after a Denver bike crash.
Why loss of consciousness is difficult to spot, how to identify it, and how to report it to medical professionals.
Not all symptoms after a concussion or mild TBI go away on their own. Some symptoms called post concussive symptoms or PCS for up to 48% of people may lost more than one year or longer.
Riding a bike is stored as implicit, procedural memory in the cerebellum and basal ganglia, areas more protected from TBI than memory centers responsible for facts and dates.
Studies estimate 40–50% of mild TBI patients leave the ER without a documented TBI diagnosis. You may still have a valid claim. Here's why.
Common signs that a bicycle defect or improper assembly caused your crash, plus exactly what to do to preserve evidence and protect your claim.
The right questions to ask before hiring a TBI attorney, including experience with normal imaging, missed ER diagnoses, and insurance challenges.
A bicycle helmet's protective lifespan is limited. Replace it after any crash, visible damage, fit changes, or every three to five years with regular use.
Multi-use trails and regional paths come with specific rules: yield to pedestrians, stay right, ride the posted speed limit, and more.
A sharrow is a painted bicycle-and-chevron marking that tells drivers and cyclists they're sharing the lane and where the cyclist should ride for safety.
Bicycles are 'vehicles' in Colorado and may ride on most roads. Here's where you can ride, when you can take the lane, and the hazards you don't have to ride through.
Modern bikes have 50+ components. Here's the full list of parts that can cause a rider to lose control if defective or improperly assembled.
Driverless Waymo taxis are now mapping and testing on Denver streets, with public rides planned for early 2026. What it means for cyclists and road users.
The current mild/moderate/severe TBI grading is being challenged by a proposed new CBI-M framework that adds biomarkers, imaging, and patient-specific modifiers.
Two new Colorado laws effective January 1, 2026 are relevant to bike and brain injury cases: e-bike class labeling (HB25-1197) and car seat replacement (HB25-1179).
T1, T2, FLAIR, fMRI, SWI, DTI, MRS, and ASL are different MRI techniques that look at different brain components. Why this matters for proving a TBI.
Attorney Dan D'Angelo designed Bike Brain Law's website to help Colorado bicycle crash and TBI victims find answers and find a trusted, experienced lawyer.
Imaging sensitivity, slice thickness, and timing all matter. A 'normal' scan does not mean no TBI occurred, particularly for mild TBI and concussion.
No. TBIs, especially mild ones, are diagnosed using clinical factors like loss of consciousness, post-traumatic amnesia, and Glasgow Coma Scale.
Loss of consciousness is only one of several diagnostic factors. Amnesia, altered mental state, neurological deficits, and intracranial lesions also matter.
Coup-contrecoup injuries, rotational forces, and whiplash can damage the brain inside the skull even without direct head impact.
Mild, moderate, severe, and complicated mild. TBI severity classification is evolving. The new CBI-M framework aims to better reflect real outcomes.
TBI is often called the 'invisible injury.' Symptoms may overlap with other conditions, be delayed, or be masked by pain from other injuries.
Big box stores routinely fail to properly assemble bikes. Improper torque on stems, bolts, or fasteners can cause sudden, catastrophic component failure.
A complete list of physical, cognitive, communication, and behavioral symptoms, plus the clinical signs doctors look for to diagnose a TBI.
Traumatic vs non-traumatic, primary vs secondary injury, and diffuse axonal injury. A foundational guide to how brain injuries occur and evolve.
Colorado-specific guidance: from stopping at the scene to filing your own crash report when police decline to investigate. Protect your case from minute one.
