When a 4,000-pound vehicle strikes a 170-pound human being, the physics are devastating. There is no crumple zone, no airbag, no seatbelt. The pedestrian absorbs the full force of the impact with nothing but their body.
Key Takeaways
- Pedestrians have no crumple zone, no airbag, and no seatbelt. The human body absorbs the full force of the impact, which is why pedestrian injuries are consistently more severe than occupant injuries.
- Traumatic brain injuries, spinal cord damage, multiple fractures, and internal organ injuries are among the most common outcomes of pedestrian-vehicle collisions.
- More severe injuries mean higher claim values. Medical costs, lifetime care needs, lost earning capacity, and non-economic damages all increase with injury severity.
This is why pedestrian accidents produce some of the most severe injuries in personal injury law — and why the legal claims that follow them are typically more complex and higher in value than standard car accident cases.
The Physics of Pedestrian Impacts
Understanding how a vehicle strikes a pedestrian explains why injuries are so predictable and so severe:
The Three-Impact Pattern
Most pedestrian collisions involve three separate impacts:
- Primary impact: The vehicle’s bumper and hood strike the pedestrian, typically hitting the legs first. For adult pedestrians, the bumper strikes below the center of gravity, causing the body to rotate onto the hood.
- Secondary impact: The pedestrian’s upper body and head strike the windshield, A-pillar, or roof of the vehicle. This impact often causes the most severe injuries — traumatic brain injury and spinal cord damage.
- Tertiary impact: The pedestrian is thrown from the vehicle and strikes the ground, often landing on their head, shoulder, or hip. The road surface causes additional injuries including road rash, fractures, and secondary head trauma.
At speeds above 25 mph, some pedestrians are thrown into the air and land significant distances from the point of impact, adding fall-related injuries to impact injuries.
The Most Common Pedestrian Accident Injuries
Traumatic Brain Injury (TBI)
TBI is the leading cause of death and long-term disability in pedestrian accidents. The head striking the vehicle or the ground — or both — can cause:
- Concussions that may resolve in weeks or produce lasting cognitive problems
- Contusions (brain bruising) that may require surgical intervention
- Diffuse axonal injury from rotational forces that tear nerve fibers throughout the brain
- Subdural and epidural hematomas (bleeding between the brain and skull)
Even “mild” TBI can cause months of headaches, difficulty concentrating, emotional changes, and inability to work. Moderate to severe TBI can result in permanent cognitive impairment, personality changes, and lifelong care needs.
Lower Extremity Fractures
Because the bumper typically strikes an adult pedestrian at knee height, leg fractures are nearly universal in pedestrian accidents:
- Tibial plateau fractures — Breaks at the top of the shinbone where it forms the knee joint. Often require surgery and may cause permanent knee problems.
- Femur fractures — Breaks in the thighbone, one of the strongest bones in the body. Require significant force and typically need surgical fixation with rods or plates.
- Ankle and foot fractures — Complex breaks that affect mobility and may require multiple surgeries.
- Pelvic fractures — Associated with internal bleeding and organ damage. Can be life-threatening and often require extended rehabilitation.
Spinal Cord and Back Injuries
The violent forces of a pedestrian impact can damage the spine at any level, causing:
- Herniated discs requiring surgery
- Vertebral fractures
- Spinal cord damage leading to partial or complete paralysis
- Chronic back pain that limits work capacity and daily activities
Internal Organ Damage
Blunt force trauma to the torso can damage internal organs:
- Spleen rupture — Requires emergency surgery; the spleen is particularly vulnerable to impact
- Liver laceration — Can cause life-threatening internal bleeding
- Kidney damage — From impact to the back or side
- Lung contusion or collapsed lung — From rib fractures penetrating the lung tissue
Soft Tissue and Disfigurement
- Road rash — Deep abrasions from sliding on pavement, which can cause permanent scarring and require skin grafts
- Degloving injuries — Where skin is torn away from underlying tissue, requiring extensive surgical repair
- Facial fractures and dental injuries — Impact with the vehicle or ground can shatter facial bones, requiring reconstructive surgery
Impact Data
At 20 mph, a pedestrian struck by a vehicle has about a 5% chance of fatal injury. At 30 mph, that rises to roughly 20%. At 40 mph, the fatality risk jumps to approximately 45%. Speed at the point of impact is the single strongest predictor of injury severity in pedestrian crashes.
Why Severe Injuries Mean Higher Claim Values
The severity of pedestrian injuries directly impacts the value of your legal claim:
Medical Costs Are Substantially Higher
A pedestrian accident victim’s medical bills typically dwarf those in a standard car accident. Emergency surgery, ICU stays, and extended rehabilitation can produce $200,000-$1,000,000+ in medical expenses. Future medical costs — follow-up surgeries, ongoing therapy, adaptive equipment — add significantly to the total.
Lost Income and Earning Capacity
Severe injuries often mean months or years away from work, and some pedestrian accident victims never return to their previous occupation. Lost earning capacity over a working lifetime can represent the largest component of a serious pedestrian injury claim.
Pain, Suffering, and Quality of Life
The non-economic impact of severe pedestrian injuries is profound: chronic pain, limited mobility, inability to play with your children, difficulty with basic self-care, emotional trauma from the accident itself, and anxiety about walking near roads. Colorado law recognizes these impacts and allows compensation for them.
Multiple Surgeries and Extended Recovery
Many pedestrian accident victims require multiple surgeries over months or years. A single pedestrian impact might require emergency surgery to stop internal bleeding, followed by orthopedic surgery to repair fractures, followed by months of rehabilitation, followed by revision surgery when hardware fails or fractures do not heal properly.
How Insurance Companies Handle Severe Pedestrian Claims
Because of the high damages involved, insurance companies fight pedestrian claims aggressively:
- Shifting blame to the pedestrian — Arguing you were jaywalking, distracted, or wearing dark clothing to reduce their payout through comparative fault
- Challenging medical necessity — Hiring defense medical experts who review your records (without examining you) and opine that treatment was excessive or unnecessary
- Surveillance — Investigating your social media and sometimes hiring investigators to follow you, hoping to capture footage that contradicts your injury claims
- Lowball offers — Making early settlement offers that cover current medical bills but ignore future costs, lost earning capacity, and non-economic damages
An experienced personal injury attorney knows these tactics and how to counter them with strong evidence, expert testimony, and willingness to take the case to trial if necessary.
Insurance Tactic
Insurance companies handling severe pedestrian claims often try to settle quickly, before the full extent of the injuries is known. A traumatic brain injury or spinal cord injury may require years of treatment and rehabilitation. Accepting a settlement before reaching maximum medical improvement almost always means leaving money on the table.

Frequently Asked Questions
Are pedestrian accidents always the driver’s fault?
No. Colorado’s comparative fault system means both parties’ actions are evaluated. However, drivers have a duty to exercise reasonable care, and the physics of a vehicle-versus-pedestrian collision mean the driver’s negligence almost always plays a significant role. Even when a pedestrian shares some fault, they can recover compensation if they are less than 50% responsible.
Why do pedestrian injuries take so long to recover from?
The combination of multiple injury types — fractures, internal injuries, head trauma — means the body is fighting on multiple fronts simultaneously. Each injury affects recovery from the others. A broken leg cannot bear weight during rehabilitation for a pelvic fracture. Pain medication for fractures may mask symptoms of a developing brain injury. The complexity of multi-system injuries makes recovery slower and less predictable.
Should I go to the hospital even if I feel okay after being hit?
Absolutely. Adrenaline masks pain and many serious injuries — internal bleeding, brain bleeds, spinal fractures — do not produce immediate symptoms. Emergency room evaluation including imaging is essential after any pedestrian accident. Delaying medical care also creates a gap in your medical records that insurance companies will use against you.
What if the driver’s insurance is not enough to cover my injuries?
Colorado’s minimum liability coverage is only $25,000 per person — nowhere near enough for serious pedestrian injuries. Options include: your own uninsured/underinsured motorist coverage, the driver’s personal assets, umbrella insurance policies, and in some cases, claims against other responsible parties (the city for dangerous road conditions, or a bar that over-served an impaired driver under Colorado’s Dram Shop Act).
Can I recover compensation for the emotional impact of a pedestrian accident?
Yes. Colorado law allows recovery for emotional distress, PTSD, anxiety, and loss of enjoyment of life. Many pedestrian accident victims develop lasting fear of crossing streets, nightmares about the impact, and anxiety in situations involving traffic. These psychological injuries are real, treatable, and compensable.
