I-285Atlanta's Perimeter
Don't drive I-285 after dark
From 2015 through 2023, 208 people died in fatal crashes on I-285. Most happened between 8 p.m. and 7 a.m.
191 fatal crashes
Composite day, 2015-2023I-285 CHANGES AT DARK
I-285 is known for daytime congestion. But its fatal crashes pile up overnight.
The 11 hours from 8 p.m. to 7 a.m. accounted for 145 fatal crashes. The other 13 hours accounted for 46.
That is more than three times as many fatal crashes in fewer hours.

The problem is getting worse
Fatal I-285 crashes have increased since 2019
In the five years from 2015 through 2019, 87 fatal crashes killed 94 people on I-285. In the four years from 2020 through 2023, 104 fatal crashes killed 114 people. More crashes and more deaths, in less time. And it is not because more people are driving: Georgians drove fewer miles in 2020 and 2021 than they did in 2019, yet statewide deaths per mile driven jumped by a third over the same stretch. Driving held roughly steady. The danger went up.
Where is the deadliest stretch of I-285?
Flat Shoals Road toward I-75 is the deadliest section of I-285
Draw a 10-mile line along the bottom of the Perimeter: from Flat Shoals Road past Bouldercrest Road, the I-675 split, Moreland Avenue and Jonesboro Road, to I-75 at Forest Park. Federal records place 46 fatal crashes and 55 deaths on that one stretch -- nearly one in four of the loop's fatal crashes, on about a sixth of its length.
I-285 exits 48 through 58
These exits serve Panthersville, Conley and Forest Park traffic. The western end feeds I-75 near Hartsfield-Jackson Atlanta International Airport; the middle passes Constitution Lakes and the Moreland Avenue/I-675 interchange.

The first harmful event
Most fatal crashes did not begin with another moving vehicle
FARS records the first event in a crash that caused injury or damage. In 107 of 191 fatal crashes, that event was not a collision with a moving vehicle. It was most often a pedestrian, traffic barrier or guardrail, rollover, or tree. The record does not show that every driver swerved, and another vehicle may have become involved later.
Exactly what we counted
The record behind this investigation
We analyzed every Georgia FARS crash from 2015 through 2023 whose primary trafficway was recorded exactly as "I-285." That produced the 191 fatal crashes and 208 deaths used throughout this story.
Mainline, ramps and the mapped record
FARS contains 54 additional fatal-crash records coded as an I-285 ramp or directional alias. Including those records produces a broader corridor total of 245 crashes and 264 deaths. We kept the map to the validated mainline geometry. Of 191 mainline crashes, 190 fell within 500 meters of the route and appear in mile bands; those crashes account for 207 deaths.
What the numbers can and cannot show
FARS includes crashes in which at least one person died within 30 days. The records show when, where and how fatal events were recorded; they do not determine fault.
Sources and data

The bottom line
If you can choose when to drive the Perimeter, choose daylight.
Nine years of federal crash records tell one story. Fatal crashes on I-285 concentrate after dark: 145 of 191 happened between 8 p.m. and 7 a.m. The toll is rising, not falling. And nearly one in four of those crashes happened along the 10 miles between Flat Shoals Road and I-75.
The record cannot explain any single crash, assign fault or promise a safe trip. But it is clear enough to act on. If a drive can wait for daylight, let it wait. If it cannot, slow down and stay alert on the overnight loop -- especially on its south side.
