Collin County recorded 1,325 reported crashes, 635 injured people, and four traffic deaths during September 2026, according to our analysis of Texas Department of Transportation CRIS records processed through October 19, 2026.
Plano had the most reported crashes, followed by Frisco and McKinney. US-75 had the highest individual roadway-label count, while failure to control speed was the most frequently recorded contributing factor.
For someone injured in a September motor vehicle accident, the effects may continue for weeks or months. Medical treatment, missed work, transportation problems, and insurance disputes can make recovery more difficult.
The Wooley Law Firm represents people injured in car, truck, and commercial vehicle collisions throughout Plano, Frisco, McKinney, Allen, and other Collin County communities.
September 2026 Collin County Crash Statistics
From September 1 through September 30, the supplied Collin County records show:
1,325 reported crashes
2,793 units involved
3,528 people involved
635 injured people
37 suspected serious injuries
Four deaths in four fatal crashes
That averages approximately 44 reported crashes and 21 injured people per day.
“People involved” includes people who were not injured. Suspected serious injuries are included within the overall injury total and should not be added to it again.
These figures cover Collin County. They are not exclusively Plano, Frisco, or McKinney statistics.
Plano Had the Most Reported September Crashes
Within the Collin County-filtered records, Plano recorded:
478 crashes
216 injured people
Five suspected serious injuries
One death
Plano accounted for approximately 36.1% of the county’s reported crashes.
Frisco ranked second with 141 crashes, followed by McKinney with 123. Together, those three cities accounted for 742 crashes, approximately 56% of the county total.
The ten cities with the most reported crashes were:
Plano: 478 crashes.
Frisco: 141 crashes.
McKinney: 123 crashes.
Allen: 64 crashes.
Wylie: 55 crashes.
Princeton: 55 crashes.
Dallas: 49 crashes.
Richardson: 42 crashes.
Melissa: 36 crashes.
Celina: 33 crashes.
An additional 76 crashes were recorded outside city limits.
Other city totals included 31 crashes in Murphy, 24 in Anna, and 22 each in Fairview and Prosper.
For cities extending across county lines, these figures include only crashes returned by the Collin County query. They do not necessarily represent the entire city.
Raw counts also do not establish that one city is inherently more dangerous than another. Traffic volume, population, roadway mileage, and reporting practices can affect the totals.
Which Collin County Roads Had the Most September Wrecks?
US-75 had the highest individual roadway-label count in the September records, with 133 crashes.
Frequently recorded highway and street labels included:
US-75: 133 crashes.
SH-289 / Preston Road: 53 crashes.
US-380: 53 crashes.
SH-121: 51 crashes.
Dallas North Tollway, recorded as “DALLAS NORTH TLWY”: 38 crashes.
SH-78: 37 crashes.
FM-544: 32 crashes.
Coit Road: 31 crashes.
Legacy Drive: 31 crashes.
SH-190: 28 crashes.
Other recorded labels included West Parker Road with 27 crashes and Dallas Parkway with 23.
These figures preserve the names and route labels in the records. Alternate names, frontage roads, tollway segments, and related routes may appear separately. Dallas Parkway and Dallas North Tollway should not automatically be treated as the same category.
The figures identify where crashes were recorded, rather than which roadway had the highest risk per mile traveled. A meaningful risk comparison would require traffic-volume and roadway-length information.
Most Common Contributing Factors in September Collin County Crashes
Failure to control speed appeared more frequently than any other contributing factor in the supplied records.
Frequently recorded specific factors included:
Failure to control speed: 340 crashes.
Driver inattention: 188 crashes.
Failure to yield while turning left: 149 crashes.
Unsafe lane changes: 133 crashes.
Failure to yield at a stop sign: 78 crashes.
Disregarding a traffic signal: 78 crashes.
Failure to drive in a single lane: 64 crashes.
Following too closely: 56 crashes.
Failure to yield from a private drive: 51 crashes.
Faulty evasive action: 49 crashes.
The records also identified alcohol impairment in 48 crashes.
Another 76 crashes included “Other—explain in narrative.” Identifying the specific conduct in those cases requires reviewing the individual reports.
A single crash may list multiple contributing factors. These counts overlap and should not be added together as separate collisions.
Injured in an Accident?
Free consultation. Tell us what happened and learn what options may be available.
Failure to Control Speed Appeared in More Than One-Quarter of Crashes
Failure to control speed appeared in 340 of the 1,325 crashes, approximately 25.7%.
That classification does not automatically mean a driver exceeded the posted speed limit. The report narrative and other evidence are needed to understand the circumstances, including whether traffic was slowing or stopped.
Driver Inattention Does Not Automatically Establish Phone Use
Driver inattention appeared in 188 crashes.
The classification alone does not identify what distracted the driver or establish that the driver was texting. Statements, recordings, and other available evidence may help clarify what happened.
Left Turns and Unsafe Lane Changes Were Frequent Reported Factors
Failure to yield while turning left appeared in 149 crashes, while unsafe lane changes appeared in 133.
These collisions can become disputed when drivers give conflicting accounts. An insurer may question which vehicle crossed a lane line, who had the right of way, or whether a driver had time to avoid the impact.
Useful evidence may include dash-camera footage, nearby surveillance recordings, independent witnesses, vehicle damage, and the sequence of impacts.
Our guide to lane-change crashes and “he said, she said” insurance disputes explains how evidence may help resolve conflicting accounts.
Crash-Report Findings Are One Part of the Investigation
A contributing-factor notation can help an investigation, but it is not a final legal determination of responsibility.
An attorney can review the report alongside photographs, recordings, witness accounts, and other evidence to evaluate how the collision occurred.
Collin County Recorded 59 Commercial Vehicle Crashes in September
The September records identify 59 crashes involving commercial motor vehicles, with:
33 injured people
Six suspected serious injuries
No recorded deaths
CMV-involved crashes represented approximately 4.5% of all reported Collin County crashes during the month.
The CMV category is broader than 18-wheelers and can include other vehicles classified as commercial motor vehicles. The flag establishes involvement, not that the commercial driver caused the collision.
A commercial truck investigation may require evidence beyond the initial police report, including:
Available onboard camera footage.
Electronic vehicle data.
Driver logs.
Dispatch communications.
Inspection and maintenance records.
Vehicle ownership and company records.
A Plano truck accident lawyer can evaluate the evidence, potentially responsible parties, and available insurance coverage.
The firm also provides information for people injured in Melissa commercial truck wrecks and other Collin County communities.
Still Receiving Treatment After a September Wreck?
A person injured in September may still be attending medical appointments or learning how the injuries affect work and daily activities.
The timing of a claim depends on factors such as:
Whether responsibility is disputed.
Whether the injuries and losses can be evaluated.
Whether additional treatment is recommended.
Whether multiple drivers or companies were involved.
What insurance coverage applies.
Whether necessary records and evidence are available.
An early settlement offer does not establish that all losses have been considered. Before signing a final release, understand which claims it resolves and how it affects your ability to seek additional compensation.
You can consult an attorney while treatment continues. You do not have to wait until every medical appointment is complete to discuss evidence and insurance issues.
What Should You Preserve After a Collin County Car or Truck Wreck?
Even if several weeks have passed, organize the evidence you have and identify information that may still be available.
Useful materials may include:
The crash report number and investigating agency.
Original photographs and videos.
Witness names and contact information.
Medical records, bills, and treatment instructions.
Prescription and related expense receipts.
Vehicle repair or total-loss documents.
Records of missed work.
Insurance correspondence and proposed settlement documents.
Our guide explains how to obtain a Texas Peace Officer’s Crash Report after a Dallas–Fort Worth collision.
Preserve dash-camera recordings in their original format when possible. Tell your attorney about nearby businesses or witnesses who may have footage or information.
Photographs of visible injuries can supplement medical records. Our article explains why photographs of bruises, cuts, and swelling matter after a truck wreck.
Necessary medical care comes first. Do not delay treatment to collect photographs or other evidence.
What If an Insurance Company Has Already Contacted You?
An adjuster may request a recorded statement, medical authorization, or signed release.
Understand who is requesting the information, what is being requested, and how the documents may affect your claim. Keep copies of correspondence and accurately explain what happened.

Data Sources and Methodology
This analysis uses a TxDOT CRIS query export filtered to Collin County and crash dates September 1–30, 2026, containing records processed through October 19, 2026. TxDOT maintains reportable crash data submitted by law enforcement and makes public data available through CRIS Query.
The export contains 1,325 unique crash IDs. Injury and death totals count people. Fatal crashes count collisions with at least one recorded death. Suspected serious injuries are included within overall injuries.
CMV totals include records marked “Yes” in the Commercial Motor Vehicle Flag field. Contributing-factor counts represent crashes listing each factor, with multiple factors possible in one collision.
City figures retain the Collin County filter. Roadway figures use recorded labels without automatically combining alternate names or related routes.
These provisional figures may differ from earlier publications or later queries. They are not adjusted for population or traffic volume and do not independently establish fault. The analysis and conclusions are those of The Wooley Law Firm, not TxDOT.
