HAMILTON, Ohio (AP) — Injury and property crashes have increased with the raising of speed limits on the state's rural interstate highways, according to the Ohio Highway Patrol.

The highway patrol said that there's been a 21 percent increase in crashes on interstate highways where the speed limit has been raised to 70 miles per hour since 2013, The Hamilton-Middletown Journal-News reported (http://bit.ly/1SBEVdd).

Highway patrol troopers have investigated nearly 334,000 crashes on all roads, state routes and interstate highways from 2011 through 2015.

A state analysis showed that crashes jumped by 19 percent— from about 8,600 in the two years before the increase to about 10,200 in the two years after.

The patrol said that during that same time, fatalities decreased slightly from 48 to 43.

"Motorists have to understand that as speed (of the car) increases, the reaction time decreases to adjust to conditions such as changing lanes, an object in the road, something falling off a truck or a deer crossing the road," said Lt. Craig Cvetan, the Ohio Highway Patrol's public affairs commander.

In 1987, Congress relaxed a restriction that required states to adopt a maximum speed limit of 55 miles per hour in order to receive highway funds. Lawmakers allowed states to increase speed limits to 65 miles per hour on rural interstates. The law was completely repealed in 1995.

Maximum speed limits are set by the states and have been on the rise since then, the newspaper reported.
