Crashing into a semi truck on the interstate is deadly more often than not.
Recently, a research institute found the measures truck companies are taking to protect you during a crash are not good enough.
Truck companies have made some improvements. They have made the metal guards on the back of the vehicles wider and stronger, which are designed to keep your car from going under the semi during a crash.
The Insurance Institute for Highway Safety conducted crash tests on the eight biggest manufacturers for truck guards in the country. After seeing this, all of those manufacturers updated their underride guards to make them stronger.
This has significantly improved the death rate of rear crashes with trucks in Tennessee from 2011 to 2016.
The law only requires a guard on the back of a semi truck, but there's still a problem with side crashes. Between 2010 and 2016, the death rate went up for these types of crashes.
Here's a look at the statistics for passenger vehicle fatalities in two-vehicle crashes involving tractor-trailers in Tennessee:2010 2011 2012 2013 2014 2015 2016 Truck Rear 4 7 6 6 13 9 10 Truck Side 7 6 3 7 8 4 13
A research engineer News4 spoke with says there is no federal law requiring side guards on semis, but they're often a lot more deadly.
"When you’re passing a trailer on the side, just be alert that they have a large blind spot. Don’t just hang out next to a trailer for a long time," said senior research engineer Matthew Brumbelow.
Brumbelow says their organization's next goal is to conduct more crash tests and get metal guard manufacturers to make side guards too.
