IIHS Toughens Top Safety Pick Criteria for 2024

The Insurance Institute for Highway Safety (IIHS) is adjusting its criteria for its Top Safety Pick and Top Safety Pick+ awards in 2024.

The change was made in an effort to challenge OEMs to "offer better protection for back seat passengers and improve their pedestrian crash avoidance systems," according to a news release. 

Despite the more stringent requirements, 71 models still qualify for 2024 awards. Of those, 22 earn Top Safety Pick+, and 49 earn Top Safety Pick. 

“We followed the tougher requirements we introduced last year with another major update to the award criteria in 2024,” IIHS President David Harkey said. “This year’s winners are true standouts, offering the highest level of protection for both vehicle occupants and other vulnerable road users.”

Automotive Fleet previously reported that IIHS also updated its criteria last year as a way of challenging OEMs to make what it says are safer vehicles. In 2023, this meant only 48 vehicle models qualified for 2023 Top Safety Pick or Top Safety Pick+ awards, compared to 101 vehicles in 2022.

What's Changing Moving Forward

These are the individual tests facing criteria changes:

• Updated side crash test
• Revised pedestrian front crash prevention evaluation
• Moderate front overlap test
• Small overlap front crash test

Updated Side Crash Test

IIHS noted that last year’s biggest change was the replacement of the original side crash test with an updated version that uses a heavier barrier traveling at a higher speed.

Initially, an acceptable or good rating was enough to garner the lower-tier Top Safety Pick award. In 2024, a good rating is required for either Top Safety Pick or Top Safety Pick+. 

Revised Pedestrian Front Crash Prevention Evaluation

In addition, vehicles now need an acceptable or good rating in a revised version of the pedestrian front crash prevention evaluation to qualify for either award.

The new version replaces the earlier daytime and nighttime tests with a single evaluation that includes some test runs in daylight and some in the dark.

Last year, vehicles could earn the lower-tier award regardless of whether they could detect and avoid pedestrians in the dark.

Moderate Front Overlap Test

In an even bigger change, IIHS noted that the updated moderate front overlap test has replaced the original evaluation in the 2024 Top Safety Pick+ requirements.

Vehicles now need an acceptable or good rating in the updated evaluation, which adds a second dummy seated behind the driver and emphasizes back seat safety. A good rating in the original moderate overlap test is still needed for the base Top Safety Pick award.

IIHS recently announced new scoring criteria for the test, leading to overall crash test rating changes on 13 vehicles, AF reported.

Small Overlap Front Crash Test

As before, to earn either award, a vehicle must offer good protection in a small overlap front crash, in which 25% of the vehicle’s width on either side collides with another vehicle or a stationary object.

This year, the driver-side and passenger-side evaluations have been combined into a single rating. The test is performed on both the driver and passenger sides, and the rating is equivalent to the lower of the two results.

Award winners also must have good or acceptable headlights equipped on all trim levels.  

Breaking Down the 2024 Winners

Hyundai Motor Group, which includes the Genesis, Hyundai, and Kia brands, has the most 2024 awards overall, with six Top Safety Pick+ and 10 Top Safety Pick awards for a total of 16.

Toyota Motor Corp., which includes the Toyota and Lexus brands, has the next highest total with one Top Safety Pick+ and 12 Top Safety Pick awards.

Mazda earns the most Top Safety Pick+ awards of any single brand, with five, as well as one Top Safety Pick. 

SUVs Take Home Most Wins

By class, small SUVs, midsize SUVs, and midsize luxury SUVs are tied for the most Top Safety Pick+ awards, with five each.

Midsize luxury SUVs, which qualify for an additional 12 Top Safety Pick awards, earn the most awards overall. Relatively few cars and pickups qualify for either award, according to IIHS.

“The high number of SUVs that earn awards probably reflects the dominance of those vehicles in the U.S. market,” Harkey said. “But it’s disappointing that only four pickups and four midsize cars earn awards, considering the popularity of those classes.” 

The changes to the 2024 award criteria are designed to push automakers to pursue higher levels of safety.

Award Winners Reveal Improvements in the Moderate Overlap Front Test

IIHS introduced the original moderate overlap front test in 1995. At the time, most vehicles earned ratings of poor or marginal.

For the past decade, virtually every vehicle tested has earned a good rating thanks to stronger vehicle structures, the introduction of front and side-curtain airbags, and a series of improvements in seat belt technology.  

That represents a big win for safety. An analysis of 14 years’ worth of crash data involving IIHS-rated vehicles shows that a driver of a model rated good in the original moderate overlap test is 46% less likely to die in a head-on crash with a similar vehicle, compared with a driver of a model rated poor.

IIHS introduced the updated test to encourage similar advancements in the back seat. Once, second-row occupants were substantially safer than those seated in the front because of the greater distance between them and the impact in a frontal crash.

In today’s vehicles, though, there is barely any deformation of the occupant compartment in the moderate overlap test. In addition, automakers have added airbags and advanced seat belts in the front seats but not often in the rear.

As a result, in vehicles from model year 2007 onward, the risk of a fatal injury is higher for belted occupants in the rear seat than in the front. 

To spur automakers to address that gap, the updated test includes an additional dummy positioned in the second row behind the driver and utilizes new metrics that focus on the injuries most frequently seen in rear-seat occupants.

Many automakers have made substantial progress since the first group of ratings was released in December 2022. Making an acceptable or good rating a requirement for Top Safety Pick+ is the next step in accelerating those improvements, IIHS stated.

Advancements to Pedestrian Front Crash Prevention Systems

The tougher standards for pedestrian front crash prevention systems are grounded in similar progress. In 2019, when IIHS launched the daytime vehicle-to-pedestrian evaluation, only 21% of the vehicles tested earned the highest rating of superior, while 44% of new models didn’t even offer the technology.

By 2023, 59% of vehicles earned superior ratings in the daytime test, and 40% also earned superior ratings in the nighttime evaluation, which was introduced a year earlier. 

An advanced or superior rating in the daytime test was required for a 2023 Top Safety Pick award, and an advanced or superior rating in the nighttime test was necessary to earn the “plus.”

For 2024, IIHS has combined the two tests into a single evaluation, as noted above, making nighttime performance essential for either award.

The superior/advanced/basic/no credit scale has been replaced by the good/acceptable/marginal/poor scale used for other IIHS evaluations. This change recognizes that technology that detects and brakes for pedestrians should be expected on all vehicles. 

Pedestrians represent an increasingly large share of crash deaths, and pedestrian fatalities are currently at their highest level since the early 1980s.

Most pedestrian crashes occur during the day, when there are more people on the roads, but three-quarters of fatal pedestrian crashes happen at night, IIHS has previously found.

“There’s still progress to be made in the protection that vehicles provide for their occupants, as the introduction of the updated moderate overlap test shows,” Harkey said. “But many of the biggest gains of the future will come from automakers and policymakers, along with all of us as car buyers and drivers, taking steps to protect everyone on the road, not just our own families.”
