T-Bone and Intersection Accident Lawyers in Denver
A T-bone crash is one of the most dangerous types of collisions. Unlike many rear-end wrecks, a side-impact crash can deliver force directly into the driver or passenger compartment with very little time to react. Intersection accidents also tend to create hard fault disputes, especially when drivers disagree about who had the green light.

Why T-Bone and Intersection Accidents Are Different
Intersection crashes are different from many other motor-vehicle collisions for three main reasons:
- Fault is often disputed, especially when there are no independent witnesses and both drivers claim they had the right-of-way.
- Injuries can be severe, because side impacts can transmit force to the head, chest, hips, and spine.
- Evidence can disappear quickly, including traffic camera footage, nearby business video, and dashcam recordings.
If you want a broader overview of how injury claims typically work, our Automobile Accidents practice page explains the general process and what to expect at each stage.
Common Causes of Intersection Crashes in Denver
Most T-bone and intersection collisions come down to a small set of preventable behaviors.
Red Light Running and Signal Violations
Many T-bone crashes happen when a driver enters the intersection against a red light or red arrow. Colorado’s traffic control signal legend explains what a steady red or red arrow requires, which matters when a driver tries to claim they “thought they could make it.”
Left-Turn Failure to Yield
A very common intersection scenario is the “left-turn T-bone,” where one driver turns left across oncoming traffic. Colorado’s vehicle turning left statute requires yielding to oncoming vehicles when making a left turn, and disputes often come down to timing, speed, and visibility.
Stop Sign and Yield Sign Collisions
Stop sign and yield sign collisions also create side-impact crashes when one driver enters without properly yielding. Colorado’s entering through highway right-of-way rules describe duties at stop and yield intersections, which can be important when the police report is unclear or incomplete.
Uncontrolled Intersections and Four-Way Stops
Not every intersection has a traffic signal. When two vehicles approach at roughly the same time on different roads, Colorado’s vehicles approaching or entering intersection rule generally gives right-of-way to the vehicle on the right, and drivers still have a duty to use due care.
For practical driving guidance, the Colorado Driver Handbook includes a plain-English discussion of right-of-way rules at intersections and four-way stops.
Distracted Driving at Intersections
Intersections demand attention, and distraction can turn a normal green light into a serious crash. If phone use is part of your case, our Distracted & Texting-While-Driving Accidents in Denver page explains how these claims are typically proved, and CDOT’s overview of the Colorado hands-free law provides the current statewide rule framework.
Speeding and Aggressive Driving
Speeding makes intersection collisions worse because it reduces reaction time and increases impact forces. Aggressive behavior also increases the likelihood of drivers trying to “beat the light,” tailgating into intersections, or making unsafe turns.
Who Is at Fault in a T-Bone Accident in Colorado?
There is no single rule that applies to every intersection crash. Fault depends on what the parties did, what the signals or signs required, and what the evidence proves.
Traffic Signals and Right Turns on Red
When a crash occurs at a signalized intersection, a key starting point is what the signal required at the time of entry. Colorado’s traffic control signal legend lays out what drivers must do at steady red, yellow, and green indications, including the conditions under which a right turn on red may occur after a stop.
Left Turns Across Oncoming Traffic
If one driver was turning left when the crash happened, the turning driver may be found at fault if they failed to yield. Colorado’s vehicle turning left rule is commonly cited in left-turn intersection collisions, and the evidence usually focuses on whether the oncoming vehicle was close enough to be an immediate hazard.
Stop Signs and Yield Signs
For stop sign and yield sign collisions, the legal question often becomes whether the entering driver stopped or slowed as required, then yielded to vehicles already in or closely approaching the intersection. Colorado’s entering through highway statute covers these duties and is frequently relevant in four-way stop disputes.
Uncontrolled Intersections
At uncontrolled intersections, right-of-way issues can come down to approach timing and which vehicle is on the right. Colorado’s vehicles approaching or entering intersection statute explains this baseline rule, while also recognizing that other right-of-way rules can modify it.
What If Both Drivers Say They Had the Green Light?
This is one of the most common fault disputes in intersection cases. When both drivers claim they had the right-of-way, the outcome usually turns on independent evidence, such as:
- Traffic camera or nearby business footage
- Witness statements from uninvolved drivers or pedestrians
- Vehicle impact points and final resting positions
- Skid marks and braking evidence
- Event data recorder information, when available
- Phone records and app activity if distraction is suspected
Even when no ticket is issued, a civil claim can still be proven through evidence. If you are trying to understand how insurers use early statements, our guide on tips for negotiating with insurance companies in Denver explains why careful communication matters in the first days after a crash.
Injuries Common in Side-Impact Collisions
Side-impact collisions often cause injuries that are more serious than they appear at first, especially when the impact occurs near the driver or passenger door.
Common injuries include:
- Concussions and traumatic brain injuries
- Neck and back injuries, including herniated discs
- Chest injuries, rib fractures, and shoulder injuries
- Hip and pelvic injuries
- Internal injuries
- Cuts, bruising, and soft tissue injuries with long-term pain
- Psychological injuries such as anxiety and PTSD
If the intersection crash involved a person on foot or a cyclist, our Pedestrian Accidents page explains crosswalk and right-of-way issues that often overlap with signal timing and turning movements.
What Your Intersection Accident Claim May Include
Intersection accident claims can include both economic and non-economic damages, depending on the facts of the case.
Economic Damages
Economic damages may include:
- Past and future medical expenses
- Lost income and reduced earning capacity
- Out-of-pocket costs, including medications and transportation to care
- Property damage and replacement costs
If you missed work after a crash, our resource on how Denver accident victims can recover lost wages explains common documentation steps that can strengthen a wage-loss claim.
Non-Economic Damages
Non-economic damages may include:
- Pain and suffering
- Emotional distress
- Loss of enjoyment of life
- Impairment, disability, or disfigurement
Evidence That Strengthens an Intersection Accident Case
Intersection cases are evidence-driven. The earlier the evidence is gathered, the stronger the claim tends to be.
Video and Camera Evidence
Helpful sources of video include:
- Traffic cameras where available
- Nearby business security cameras
- Doorbell cameras from homes near the intersection
- Dashcams from uninvolved vehicles
A practical step is to identify camera locations immediately after the crash, then act quickly before recordings are overwritten. The checklist in our what to do after a car accident guide can help you organize what to collect and when.
Vehicle Data and Phone Evidence
Depending on the vehicles involved, evidence may include:
- Event data recorder information
- Infotainment system logs and GPS data
- Cell phone records when distraction is suspected
When you suspect the other driver was distracted, our Distracted & Texting-While-Driving Accidents in Denver page explains what types of proof can matter most in negotiations.
Scene Evidence and Witnesses
Scene evidence and witness information can include:
- Photos showing lane markings, signs, and signal heads
- Debris fields and impact points
- Skid marks, gouge marks, and braking distance
- Witness contact information, including passengers in other cars
- Weather and visibility conditions
Insurance Issues in T-Bone and Intersection Cases
Intersection crashes can create insurance complications, especially when coverage limits are low or liability is contested.
UM/UIM and Hit-and-Run Coverage
If the at-fault driver is uninsured, underinsured, or leaves the scene, your own policy may matter. Our Uninsured & Underinsured Motorist (UM/UIM) Claims page explains how UM/UIM works, and our Hit-and-Run Accidents page covers practical steps when the other vehicle cannot be identified.
Commercial Vehicles and Rideshare
If the at-fault driver was working or driving a fleet vehicle, the claim may involve commercial insurance and additional evidence sources. Our Commercial Vehicle Accidents page explains why these cases often require early preservation of dashcam and telematics data.
If the crash involved an Uber or Lyft driver, our Uber & Lyft (Rideshare) Accidents in Denver page breaks down the different coverage layers that can apply depending on the driver’s app status.
MedPay and Early Medical Bills
MedPay can help pay medical bills early in a case, but insurers may try to recover it later depending on the circumstances. Our article on how MedPay works after a Colorado car accident explains common issues that come up after treatment begins.
Colorado Deadlines You Can’t Miss
Most injury claims arising out of the use or operation of a motor vehicle fall under Colorado’s limitations framework, and the three-year statute for many civil actions is found in C.R.S. § 13-80-101 as part of that structure.
Fault allocation can also affect the value of your claim. Colorado follows modified comparative negligence under C.R.S. § 13-21-111, which means compensation may be reduced if you are found partially responsible.
If a government vehicle or public entity may be involved, Colorado’s notice requirements can be much shorter than typical lawsuit deadlines under C.R.S. § 24-10-109, so early legal review can be critical.
What to Do After an Intersection Crash in Denver
If you are able, these steps can help protect your health and your claim:
- Call 911 and request medical help if needed.
- Ask for a police report number and the responding agency information.
- Take photos of the intersection, including traffic lights, signs, lane markings, and vehicle positions.
- Collect witness names and contact information, including passengers and bystanders.
- Identify nearby cameras, including businesses on the corners and vehicles with dashcams.
- Avoid guessing about fault at the scene, and do not minimize symptoms if you are not sure how you feel.
- Get medical evaluation promptly, then follow through on recommended care.
- Save receipts and records, including prescriptions, mileage, and time missed from work.
- If the insurer requests a recorded statement, consider reviewing the process in our tips for negotiating with insurance companies in Denver guide before responding.
- Use the Contact Us form to request a free consultation if you want help preserving evidence and evaluating coverage.

FAQs About T-Bone and Intersection Accidents in Denver
Who Is Usually at Fault in a T-Bone Accident?
Fault depends on what controlled the intersection and what each driver did. Many T-bone cases involve red-light violations under Colorado’s traffic control signal legend rules, failure to yield at a stop or yield intersection under the entering through highway statute, or left-turn failures under the vehicle turning left requirements.
What If Both Drivers Say They Had the Green Light?
When both drivers claim the green, the case often comes down to video, witnesses, and crash reconstruction. Early action to identify cameras and preserve recordings is important, and the checklist in what to do after a car accident can help you act quickly.
What If I Was Turning Left When I Was Hit?
Left-turn cases frequently involve the duty to yield to oncoming vehicles, and Colorado’s vehicle turning left statute is often part of the analysis. Evidence about speed, visibility, and signal phase can be critical in determining whether the oncoming vehicle was an immediate hazard.
What If the Other Driver Is Uninsured or Left the Scene?
If the other driver is uninsured, underinsured, or cannot be identified, UM/UIM coverage may apply. Our Uninsured & Underinsured Motorist (UM/UIM) Claims page explains how that coverage works, and our Hit-and-Run Accidents page explains practical steps after a driver flees.
How Long Do I Have to File an Intersection Accident Claim in Colorado?
Many motor-vehicle injury claims fall within Colorado’s limitations framework, including the three-year structure described in C.R.S. § 13-80-101, but the right deadline depends on the facts. If a public entity may be involved, notice requirements under C.R.S. § 24-10-109 can apply on a much shorter timeline.
