Wisconsin transportation officials say traffic deaths increased by 13 percent in 2015.
The state ended the year with 556 fatalities, up from 494 in 2014. Department of Transportation officials said in a news release that warm spring weather, cheap gas and an improving economy likely contributed to more vehicles on the road and miles traveled.
Agency officials won’t have the total miles traveled ready for several more months, however.
They also said they don’t have enough data yet to tell if increasing the speed limit to 70 mph on some interstates and freeways contributed to crashes.
DOT officials didn’t immediately respond to an email inquiring about what sort of data they were collecting on the 70 mph speed limit and when it would be available.
