Detroit is one of the most dangerous big cities in the country to get behind the wheel. Between 2017 and 2021, an average of 108 people were killed each year in traffic crashes inside the city, and Detroit's per-capita traffic fatality rate ranks second among large U.S. cities.1 The wrecks driving those numbers tend to be the violent ones: a car struck in the side at an intersection, a vehicle that runs off the road and rolls, or two front ends meeting head-on.
This page maps where those three patterns show up across metro Detroit, using data the local agencies actually publish. Across the seven-county southeast Michigan region there were 129,583 reported crashes in 2024, with 402 people killed and 2,211 seriously hurt.2 Statewide, Michigan recorded 288,880 crashes and 1,099 deaths the same year.3 Rollovers, T-bones, and head-ons make up a large slice of the serious end of those totals.
T-bone crashes and Detroit's intersections
A T-bone, what crash reports call an angle crash, is a side impact: one vehicle hits the side of another, almost always at an intersection. There isn't much car between the door and the striking bumper, so these turn into injuries fast.
Intersections are the biggest single source of serious harm in the region. SEMCOG counted 125 intersection-related deaths and 912 serious injuries across southeast Michigan in 2024, the highest serious-injury figure in a decade. Those crashes accounted for 31% of the region's traffic deaths and 41% of its serious injuries, the largest combined share of any factor the agency tracks.2
Gratiot Avenue (M-3) shows the problem up close. On the 8.5-mile run from I-375 to 8 Mile Road (M-102), an MDOT road safety audit tallied about 2,899 crashes over five years, and angle collisions were 21% of the fatal and serious-injury wrecks and roughly 20% of crashes at every severity.4 Geometry is part of it. Gratiot cuts across Detroit's street grid on a diagonal, so almost every intersection along it sits at a skew, which shortens sight distance and stretches the path a turning driver has to clear.4 The corridor meets a string of heavy cross-streets on its way north, among them Conner, Van Dyke (M-53), the I-94 interchange, 7 Mile, and 8 Mile.4 These wrecks don't spread evenly through the day, either. Two-thirds of Gratiot's fatal and serious-injury crashes happened between 3 p.m. and midnight, when the evening rush overlaps with fading light.4
Rollovers and run-off-road wrecks
Most rollovers start as single-vehicle, run-off-road events. A driver drifts or gets pushed off the pavement, a tire catches, and the vehicle trips and flips. SEMCOG groups these under lane departures, and in 2024 lane departures were the top factor in fatalities for the region, tied to 155 deaths and 568 serious injuries, which is 39% of every traffic death in southeast Michigan.2
Speed is the multiplier. On Gratiot, single-vehicle crashes were the most common fatal and serious-injury type at 38%, ahead of every other pattern, and the auditors flagged driving too fast for conditions as a recurring cause.4 The road is posted at 35 mph, but drivers routinely move much faster.5 About one in three of the corridor's fatal and serious crashes were hit-and-run.4 The same physics plays out on the freeways that ring the city, the Lodge (M-10), I-75, I-96, and I-94, where a run-off-road at 70 mph rarely ends without a rollover. Impairment keeps feeding this category too. Alcohol- and drug-related crashes killed 145 people in the region in 2024, 36% of all its traffic deaths.2
Head-on crashes and the left-turn trap
Head-on crashes are rarer than the other two, but they carry the worst odds, because the closing speed is the sum of both vehicles. Many of them are not two cars racing toward each other on a rural two-lane. They start with a left turn, when a driver crosses the oncoming lanes and misjudges the gap.
On Gratiot, head-on collisions made up about 8% of the fatal and serious-injury crashes, and head-on/left-turn crashes added another 7%, so roughly one in seven of the corridor's worst wrecks involved a front-end hit.4 The road's wide center two-way left-turn lane lets drivers turn almost anywhere, which spreads those conflict points along the whole length of the corridor instead of confining them to signals.4 Crossing the centerline is the other half of SEMCOG's lane-departure category, the same group that leads the region in deaths.2
What Detroit and MDOT are changing
The agencies know where these crashes cluster. SEMCOG keeps a High Injury Network that flags every road segment with a fatal or serious-injury crash over a five-year window, which gives cities a ranked list of where to spend first.6
On Gratiot, the City of Detroit landed a $12.5 million federal Safe Streets and Roads for All grant, aimed largely at slowing traffic on a corridor that saw 2,542 crashes and 38 deaths between 2019 and 2023.5 On I-94, MDOT's modernization project will rebuild seven miles of freeway from Conner Avenue to the I-96 interchange, widen the shoulders, lengthen the entrance and exit ramps, and pull out the outdated left-lane ramps at the I-94/M-10 (Lodge) interchange, the kind of merge points that force weaving across fast lanes.7 Much of that stretch was built in the 1950s and has never been reconstructed.7 Detroit's own Comprehensive Safety Action Plan sets a Safe System goal of ending severe crashes and pushes intersection redesigns, raised medians, and better lighting onto the worst corridors first.1
If a rollover, T-bone, or head-on put you here
None of that engineering helps the person already in the ambulance. If you were in a crash at one of these intersections or on one of these freeways, get the police report number, photograph the scene and the final rest positions of the vehicles if you safely can, and see a doctor even if you feel fine, because side-impact and rollover injuries often surface a day or two later.
