New Orleans rollover, T-bone, and head-on hotspots

Not every crash does the same damage. A fender tap in stop-and-go traffic on the Pontchartrain Expressway is one thing. Getting hit square in the door at a Chef Menteur Highway signal, meeting a wrong-way driver on I-10, or rolling a pickup off an elevated ramp is another. Three collision shapes (right-angle "T-bone" wrecks, head-on and wrong-way crashes, and rollovers) cause a large share of the worst injuries and deaths on New Orleans-area roads, and each tends to happen in particular places for particular reasons.

The scale is real. The City of New Orleans counted 233 people killed in motor-vehicle crashes inside Orleans Parish from 2016 through 2020 (the federal FARS database counts 221 for the same span), a fatality rate of 11.92 per 100,000 residents, and the Federal Highway Administration has named New Orleans a Pedestrian and Bicycle Safety Focus City.¹ Statewide, Louisiana logged 143,207 crashes in 2023, with 755 fatal crashes and 811 people killed.² The state's fatality rate hit 1.76 deaths per 100 million miles driven in 2021, well above the national 1.33, and Louisiana is an FHWA focus state for both roadway departure and intersection crashes.³ Those two federal categories line up almost exactly with rollovers and T-bones.

T-bone crashes and the intersection problem

A T-bone, or right-angle crash, happens when the front of one vehicle hits the side of another, usually after someone runs a red light, misses a stop sign, or turns across oncoming traffic. Side impacts hurt people because a door and pillar give far less crush space than a hood or a trunk.

Intersections are where this concentrates. Reviewing five years of crashes on the main St. Bernard Parish corridors just downriver from Orleans (Judge Perez Drive/LA 39, Paris Road/LA 47, and St. Bernard Highway/LA 46), the New Orleans Regional Planning Commission logged 3,699 crashes from 2017 through 2021. Right-angle collisions were the third most common type at 550, behind rear-end crashes (1,035) and a catch-all "other" group.⁴ Nine of the ten worst intersections in that study were signalized, and those ten together made up more than 30 percent of the crashes on the corridors.⁴ The busiest was Judge Perez Drive at Paris Road, with 338 crashes in five years.⁴

Inside Orleans Parish the same setup shows up on the state-highway corridors the city singled out in its Comprehensive Safety Action Plan: North Claiborne Avenue (LA 39), the Tulane Avenue and South Claiborne corridor, Elysian Fields Avenue, and US 90 through Gentilly Boulevard and Chef Menteur Highway.¹ Wide multi-lane surface streets, frequent signals, and heavy turning traffic are the conditions that produce angle crashes.

If you were broadsided, write down the signal timing, the direction each car was going, and whether a light or sign controlled the intersection. That detail usually decides fault.

Head-on and wrong-way crashes on the interstates

Head-on crashes are less common and far deadlier, because the closing speed is both vehicles combined. In the St. Bernard corridor review, only 71 of the 3,699 crashes were head-on.⁴ The real danger shows up where a driver ends up pointed the wrong way.

That keeps happening on I-10. In September 2025, a driver entered I-10 the wrong way from US 51 in LaPlace, drove east in the westbound lanes near milepost 210, and hit a Nissan Altima head-on. Patricia Saidu, 21, was killed and both vehicles caught fire, according to Louisiana State Police Troop B, which patrols the New Orleans area.⁵ A separate wrong-way crash that April, on I-10 in Ascension Parish, killed an unbelted driver whose truck burst into flames after striking a tractor-trailer.⁶ The pattern repeats: a late-night wrong-way entry, then fire.

Louisiana has been putting up physical separation to stop it. On I-10 through New Orleans East, DOTD's H.014585 project installed a mix of concrete and high-tension cable barriers between the main lanes and the service roads from Chef Menteur Highway to I-510, an $8.94 million job that began in July 2022.⁷

The Lake Pontchartrain Causeway is its own case. On December 17, 2024, sudden dense fog and inattentive driving set off six separate multi-vehicle crashes on the twin two-lane spans and sent 33 people to hospitals, with no deaths.⁸ The bridge's general manager, Carlton Dufrechou, said 60 to 70 percent of Causeway crashes usually trace to inattentive driving rather than weather.⁸

Rollovers and running off the road

A rollover happens when a vehicle leaves its lane and trips on something (a curb, a soft shoulder, a guardrail) or when a top-heavy SUV or pickup gets pushed past its tipping point. It is the classic single-vehicle, run-off-road outcome. Nationally, the IIHS found rollovers involved in 28 percent of passenger-vehicle occupant deaths in 2024, and the rollover share of single-vehicle occupant deaths (47 percent) ran almost four times higher than in multiple-vehicle crashes (13 percent). Pickups (38 percent) and SUVs (33 percent) rolled far more often than cars (20 percent).⁹

Louisiana calls this roadway departure, and it is one of the state's leading killers. Louisiana recorded 313 lane-departure deaths in 2023, 47 of them on interstates.² In that same report, single-vehicle crashes killed more vehicle occupants than multi-vehicle crashes in every year tracked.² On the St. Bernard corridors, 11 of the 18 people killed died in roadway-departure crashes.⁴ Around New Orleans the risk clusters on elevated and high-speed roads: the I-10 High Rise over the Industrial Canal, the I-610 and I-510 connectors, the Chef Menteur run through New Orleans East, and the long bridge approaches over water where there is little room to catch a slide.

After a serious crash

For scale, our own monthly crash reports for Baton Rouge, the closest Louisiana metro we track, counted 15,038 crashes in 2025 alone.¹⁰ New Orleans carries comparable volume, and a rollover, T-bone, or head-on can leave you with hospital bills before you ever see a police report.

A few practical steps. Get the crash report number from the responding agency, whether that is NOPD, a parish sheriff, or Louisiana State Police. Photograph where the vehicles came to rest and the point of impact. Get checked out even if you feel fine, because side impacts and rollovers cause injuries that surface days later. Two-thirds of New Orleans traffic deaths happen in neighborhoods the federal government classifies as historically disadvantaged, so many of the people hurt on these roads have the fewest resources to absorb it.¹ If fault is contested and the injuries are serious, you can find local counsel through the thatcarhitme.com legal directory.
