The Insurance Institute for Highway Safety's (IIHS') new crash test criteria are tripping up many cars and trucks.

The organization updated its rules for 2023 making it harder for vehicles to achieve its highest ratings.

The evaluation now includes a side-impact test that simulates a larger, heavier vehicle ramming into the side of the test subject at a faster speed.

The weight has been increased from 3,300 pounds to 4,200 pounds and the speed from 31 mph to 37 mph to better reflect current road conditions.

FED OFFICIAL CONCERNED THAT ELECTRIC VEHICLES MIGHT BE GETTING TOO HEAVY FOR SAFETY

The IIHS has also started to factor in the nighttime performance of automatic emergency braking systems faced with avoiding running into a pedestrian and requires that the best headlights be available across an entire model lineup.

As a result, the overall number of vehicles achieving either a Top Safety Pick+ or Top Safety Pick designation has dropped from 101 to just 48.

"The number of winners is smaller this year because we’re challenging automakers to build on the safety gains they’ve already achieved," said IIHS President David Harkey. "These models are true standouts in both crash worthiness and crash prevention."
