More speed means more deaths

MILWAUKEE - There's a proposal to raise Wisconsin's maximum speed limit from 65 to 70.  What's the impact?

"There's no free lunch here." said Russ Rader with the Insurance Institute for Highway Safety.

Rader explains there's a clear trade off when you raise the speed limit.  You get roads that are less safe.

"The laws of physics haven't been repealed," he said. "Anytime you allow someone to go faster, it means the likelihood of crashes increases and the energy in those crashes increases exponentially."

Rader admits cars are safer today, but he says study after study found increases in deadly crashes after the speed limit went up.

A study in 2002 found states that increased speed limits from 65 to 70 on rural roads experienced 35 percent more deaths after the speed limits were raised.
