Collin County recorded 12,148 reported crashes, 5,462 injured people, and 49 traffic deaths from January 1 through September 30, 2026, according to our analysis of Texas Department of Transportation CRIS records.
Compared with the same nine months in 2025, crashes declined approximately 1.5%, and the number of injured people declined approximately 9.2%. However, suspected serious injuries increased from 267 to 329—an increase of approximately 23.2%.
Commercial vehicle crashes followed a similar pattern. Collin County recorded fewer crashes involving commercial motor vehicles, but suspected serious injuries in those crashes increased from 18 to 26.
This report follows our earlier analysis of Collin County car wrecks during the first half of 2026. The updated nine-month records show that suspected serious injuries remained substantially above 2025 levels, although the third-quarter comparison was more encouraging.
The Wooley Law Firm represents people injured in car, truck, and commercial vehicle wrecks throughout Plano, Frisco, McKinney, Allen, and the rest of Collin County.
Collin County Crash Statistics: January–September 2026 Compared With 2025
The Collin County-filtered records show the following changes between January 1 and September 30 of each year:
Reported crashes: Decreased from 12,337 in 2025 to 12,148 in 2026—189 fewer crashes, a decline of approximately 1.5%.
People injured: Decreased from 6,014 to 5,462—552 fewer injured people, a decline of approximately 9.2%.
Suspected serious injuries: Increased from 267 to 329—62 additional suspected serious injuries, an increase of approximately 23.2%.
Traffic deaths: Decreased from 52 to 49—three fewer deaths, a decline of approximately 5.8%.
Suspected serious injuries are included within the overall injury total. They should not be added to it again.
During the first 273 days of 2026, Collin County averaged approximately 44 reported crashes and 20 injured people per day.
The overall declines are meaningful, but so is the increase in suspected serious injuries. Fewer crashes and fewer injured people overall can occur alongside an increase in the number of people with injuries classified as suspected serious.
Did Collin County’s Increase in Serious Injuries Continue Into the Third Quarter?
Our first-half report identified a substantial increase in suspected serious injuries. The nine-month results show that the county remained above the prior year, but third-quarter suspected serious injuries were nearly unchanged from third-quarter 2025.
The updated records show:
First quarter: 95 suspected serious injuries in 2026, compared with 74 in 2025.
Second quarter: 117 in 2026, compared with 75 in 2025.
Third quarter: 117 in 2026, compared with 118 in 2025.
The nine-month increase was therefore concentrated in the first and second quarters. Third-quarter 2026 recorded one fewer suspected serious injury than the corresponding quarter in 2025.
That distinction matters. The cumulative increase remained substantial, but the third-quarter results did not show the same year-over-year growth seen earlier in the year.
The data does not independently explain why these classifications changed or establish the medical outcome for any individual person.
Third-Quarter 2026 Compared With the First and Second Quarters
First Quarter: January–March 2026
Collin County recorded:
3,767 crashes
1,505 injured people
95 suspected serious injuries
16 deaths
The first quarter had the lowest crash, injury, and suspected serious injury totals of the first three quarters.
Second Quarter: April–June 2026
Collin County recorded:
4,282 crashes
1,989 injured people
117 suspected serious injuries
17 deaths
The second quarter had the highest crash and overall injury totals.
Third Quarter: July–September 2026
Collin County recorded:
4,099 crashes
1,968 injured people
117 suspected serious injuries
16 deaths
Third-quarter crashes and overall injuries declined from the second quarter, while suspected serious injuries remained unchanged.
Third Quarter Versus Second Quarter
Compared with April–June, July–September recorded:
183 fewer crashes, a decrease of approximately 4.3%.
21 fewer injured people, a decrease of approximately 1.1%.
The same number of suspected serious injuries: 117.
One fewer death.
The reduction in overall injuries was smaller than the reduction in crashes.
Third Quarter Versus First Quarter
Compared with January–March, the third quarter recorded:
332 more crashes, an increase of approximately 8.8%.
463 more injured people, an increase of approximately 30.8%.
22 more suspected serious injuries, an increase of approximately 23.2%.
The same number of deaths: 16.
These are comparisons of quarterly totals. The first quarter contained 90 days, the second contained 91, and the third contained 92. The figures are not adjusted for traffic volume or miles traveled.
Third-Quarter 2026 Compared With Third-Quarter 2025
Comparing July through September in both years shows decreases in crashes and injuries:
Crashes: Decreased from 4,263 to 4,099, approximately 3.8%.
People injured: Decreased from 2,110 to 1,968, approximately 6.7%.
Suspected serious injuries: Decreased from 118 to 117.
Deaths: Increased from 15 to 16.
The one additional death should be understood alongside the underlying counts. A small numerical change can produce a comparatively larger percentage change when totals are low.

Plano Had the Most Reported Crashes in Collin County
Plano recorded 4,222 crashes within the Collin County dataset during January–September 2026, compared with 4,389 during the same period in 2025.
That represents 167 fewer crashes, a decrease of approximately 3.8%.
Plano accounted for approximately 34.8% of the county’s reported crashes.
Frisco ranked second with 1,618 crashes, followed by McKinney with 1,164. Together, these three cities accounted for approximately 57.7% of the county total.
The ten cities with the most reported crashes in the Collin County-filtered records were:
Plano: 4,222 crashes.
Frisco: 1,618 crashes.
McKinney: 1,164 crashes.
Allen: 709 crashes.
Dallas: 529 crashes.
Wylie: 504 crashes.
Richardson: 356 crashes.
Princeton: 348 crashes.
Celina: 324 crashes.
Melissa: 311 crashes.
An additional 628 crashes were recorded outside city limits.
For cities extending into more than one county, these figures cover only the crashes returned by the Collin County query. They do not necessarily represent the entire city.
Princeton, Celina, and Melissa Recorded More Crashes
Although countywide crashes declined, several communities recorded increases.
Princeton
Princeton increased from 284 to 348 crashes—64 additional crashes, an increase of approximately 22.5%.
Celina
Celina increased from 268 to 324 crashes—56 additional crashes, an increase of approximately 20.9%.
Melissa
Melissa increased from 235 to 311 crashes—76 additional crashes, an increase of approximately 32.3%.
Fairview
Fairview increased from 106 to 182 crashes—76 additional crashes, an increase of approximately 71.7%.
These figures identify changes in reported totals. They do not establish why crashes increased. Smaller starting totals can also produce large percentage changes from relatively modest numerical increases.
Meanwhile, Frisco recorded approximately 4.7% fewer crashes, McKinney recorded approximately 2.5% fewer, and Allen recorded approximately 6.7% fewer.
Which Collin County Roads Had the Most Reported Wrecks?
US-75 had the highest individual roadway-label count in the supplied 2026 records, with 1,209 crashes.
That compares with 1,311 during January–September 2025, a decline of approximately 7.8%.
Other frequently recorded roadway labels included:
SH-289, commonly known as Preston Road: 606 crashes.
SH-121: 591 crashes.
US-380: 532 crashes.
Coit Road: 330 crashes.
SH-78: 326 crashes.
Dallas Parkway: 264 crashes.
SH-190: 247 crashes.
West Parker Road: 241 crashes.
Legacy Drive: 233 crashes.
The records separately list 272 crashes under “DALLAS NORTH TLWY” and 182 under “DALLAS NORTH TOLLWAY.” These naming differences show why an individual label should not automatically be treated as a complete corridor total.
The roadway figures above preserve the recorded categories rather than combining potentially overlapping or differently defined corridors.
Several labels showed declines, including US-75, SH-289, and US-380. West Parker Road increased from 213 to 241 crashes, approximately 13.1%.
These are raw counts. They do not establish which road has the highest crash risk because they are not adjusted for traffic volume, roadway length, or miles traveled.
Commercial Vehicle Crashes Declined, but Suspected Serious Injuries Increased
Collin County recorded 571 crashes involving commercial motor vehicles during January–September 2026, compared with 591 during the same period in 2025.
That represents 20 fewer CMV crashes, a decline of approximately 3.4%.
However, injuries in those crashes moved in the opposite direction:
People injured: Increased from 176 to 179.
Suspected serious injuries: Increased from 18 to 26—eight additional suspected serious injuries, approximately 44.4%.
Deaths: Decreased from five to three.
The increase in suspected serious injuries comes from relatively small counts, so both the percentage and the actual increase of eight are important.
CMV involvement does not establish fault. The category is also broader than tractor-trailers and may include other vehicles classified as commercial motor vehicles.
Third-Quarter Commercial Vehicle Results
During July–September 2026, Collin County recorded:
182 CMV-involved crashes
64 injured people
Nine suspected serious injuries
One death
That compares with 220 CMV crashes, 66 injured people, nine suspected serious injuries, and one death during the second quarter.
Third-quarter CMV crashes declined approximately 17.3% from the second quarter, while suspected serious injuries and deaths remained unchanged.

Why Evidence Matters After a Collin County Car or Truck Wreck
Countywide crash statistics cannot determine responsibility for an individual collision or the value of an injury claim.
A claim requires evidence showing how the wreck happened, which parties may be responsible, and how the collision affected the injured person.
Useful evidence may include:
Police crash reports and supplements.
Dash-camera footage and nearby surveillance recordings.
Witness names and contact information.
Photographs of vehicle damage and the scene.
Available vehicle electronic data.
Medical records, bills, and treatment recommendations.
Documentation of missed work and other losses.
Our guide explains how to obtain a Texas Peace Officer’s Crash Report after a Dallas–Fort Worth wreck.
Commercial truck investigations may also involve driver logs, dispatch communications, maintenance records, inspection reports, onboard video, and company records. The available evidence depends on the vehicle and circumstances.
Vehicles may be repaired and recordings may be overwritten. Preserving evidence early can help resolve conflicting accounts of what happened.
Getting Help After a Serious Collin County Collision
An injured person may be managing treatment, missed work, transportation problems, and insurance requests at the same time.
The Wooley Law Firm can investigate the collision, identify potentially responsible parties and available coverage, review medical documentation, and help present the losses supported by the evidence.
Our Dallas car accident lawyer resource explains common issues in North Texas injury claims. We also provide information for people injured in commercial truck wrecks in Melissa and other Collin County communities.
Every claim depends on its facts. An insurance evaluation should account for the documented effects of the collision on the individual, including ongoing treatment and limitations when supported.

Data Sources and Methodology
This analysis uses two TxDOT Crash Records Information System query exports filtered to Collin County and the periods January 1–September 30, 2025, and January 1–September 30, 2026. TxDOT makes public crash data available through CRIS Query.
The 2026 export reflects records processed through October 15, 2026. The 2025 export reflects records processed through October 16, 2026. Quarterly figures were calculated using each record’s crash date. CMV results include records marked “Yes” in the Commercial Motor Vehicle Flag field.
The updated 2026 file contains 8,049 first-half crashes, compared with 8,044 in our earlier article. This follow-up uses the updated file consistently for all 2026 comparisons. CRIS totals can change as reports and supplemental information are processed.
Injury and death figures count people rather than crashes. Suspected serious injuries are included within total injuries and reflect the recorded classification, rather than an independent medical assessment by our firm.
City figures are county-filtered. Roadway figures use recorded labels without automatically combining alternate names or related routes. Totals are not adjusted for population, traffic volume, or roadway length.
The data does not independently explain why totals changed or establish fault. The analysis and conclusions are those of The Wooley Law Firm, not TxDOT.
