Study finds EVs are too heavy for US highway safety measures

Studies by the University of Nebraska revealed another issue with electric vehicles….the way highways are designed for safety might not be enough because of the extra weight that EVs carry due to their large battery.

Crash test data released by the university shows EVs typically weight more than gas-powered cars and can easily crash through steel highway guardrails that are not designed to withstand the extra force.

The Associated Press reported EVs can weigh up to 50% more than most gas-powered cars on the highways today. They also have a lower center of gravity and as a result, the guardrails in place on the nation’s highways weren’t built to withstand the force of an EV.

If the nation increases the number of electric vehicles as the Biden Administration wants, could it mean a re-engineering of the safety measures in place on highways? As engineers at the University of Nebraska found out, the current highway system was not designed to handle vehicles greater than 5,000 pounds.
