Illinois traffic deaths just fell to their lowest level since 2019. Not everyone is safer.

1,172 people died on Illinois roads in 2025, according to provisional numbers from the Illinois Department of Transportation. That is the lowest annual total since 2019, and the fourth straight yearly decline since deaths peaked at 1,341 in 2021.

And 2026 is on pace to fall further. Through August 12, IDOT's provisional count shows 561 deaths statewide, compared with 722 at the same point last year. That is 161 fewer families getting the worst phone call of their lives, a 22.3% drop.

Those are the headlines. The details are messier. Underneath the statewide decline, motorcyclist deaths rose, work zone deaths more than doubled, and deaths in crashes involving semi-trucks climbed almost 16%. Safer on average does not mean safer for everyone.

Here is what two decades of IDOT data show, where 2025 actually improved, and where it didn't.

Who actually got safer

The cleanest improvement in the 2025 data involves seat belts. Deaths of occupants who weren't wearing one, or wore one improperly, fell from 233 to 219. That continues a five-year trend: in 2021 that number was 337.

Cyclists had a notably better year too. Pedalcyclist deaths dropped from 37 to 28, the lowest figure in the dashboard's five-year window. Deaths on city streets and on county and township roads both edged down as well.

And the total number of fatal crashes fell from 1,084 to 1,070. For context, that number was 1,210 in 2021. Illinois is producing meaningfully fewer deadly crashes than it did four years ago.

Who didn't

Work zones had the worst reversal in the data. After a record-low 15 deaths in 2024, work zone deaths more than doubled to 36 in 2025. One bad year does not make a trend, but it wiped out most of what 2024 gained.

Motorcyclist deaths rose from 145 to 153 while nearly everything else fell. Riders made up about 13% of all Illinois road deaths in 2025, despite motorcycles being involved in roughly 1% of crashes. We wrote more about that gap in our motorcycle accident work.

Deaths in crashes involving semi-trucks climbed from 115 to 133, and interstate deaths rose from 163 to 179. Pedestrian deaths ticked up from 217 to 219, which sounds flat until you look at the longer arc: pedestrians were 14.6% of Illinois road deaths in 2020 and nearly 19% in 2025. Walking is claiming a growing share of a shrinking total.

The county map moved too

Statewide numbers hide a lot. Cook County, which accounts for more than a quarter of all Illinois road deaths, dropped from 365 to 342. LaSalle County fell from 28 deaths to 12, and St. Clair County from 45 to 32.

Other counties went the wrong way. Champaign County nearly tripled, from 10 deaths to 29. Adams County went from 1 to 9, and Lee County from zero to 8.

A caution before reading too much into any single county: one-year swings are noisy, and small counties can double or halve off a base of two or three deaths. The five-year trend matters more than any one row.

What the good news doesn't say

Fewer deaths does not mean fewer crashes. Illinois recorded 303,913 total crashes in 2024, the highest total in the five years covered by IDOT's latest trends report, along with 89,023 injuries. Both went up while deaths went down. The roads are producing more wrecks that kill less often.

That distinction matters if you're one of the 89,000. A crash you survive can still mean surgery, months off work, and an insurance company working hard to pay you as little as possible. It's not fair, but it's how they operate.

If that's your situation, focus on your health first. Then talk to an attorney before you talk to the other side's insurer. The consultation is free, and there is no fee unless we recover money for you.
