Raising the speed limit on highways could lead to more crashes on local roads. That’s according to new research by the AAA Foundation for Traffic Safety.

AAA of Michigan’s Adrienne Woodland says they have ideas to make things safer.

“One of the things we talked about was education, making public awareness campaigns focused on the riskier drivers, as well as changing road design, narrow lane, speed, humps, roadway, landscaping, and curb extensions could slow the speeds on the local roads,” Woodland said.

Woodland says the study looked at crash data before and after speed limit increases on interstates in Georgia, Michigan, and Oregon.

Hot spot observations were conducted on roads within a one-mile radius of interstates, and researchers found many instances where speed-related crashes increased on nearby roads following the interstate speed limit change, suggesting that drivers exiting the highway continued their faster tendencies.
