On January 1, 2015, the speed limit was increased from 55 mph to 65mph on the Spaulding Turnpike between exit 9 in Dover and exit 16 in Rochester. As of January 1, 2014, the speed limit on I-93 was raised from 65mph to 70mph excluding the portion of I-93 through Franconia Notch.
#When were speed limits created drivers#
New Hampshire has followed suit on some of its highways to increase the speed limit to the speeds that most drivers had been driving anyways. The research further determined a decrease in the number of crashes by 11%. Despite the increase in speed however, crashes actually declined in the test zones. For example, in Utah, when the speed limit was changed from 75 miles an hour to 80 miles an hour, the actual speed of vehicles on the highway rose from 83 miles an hour to 85 miles an hour, although overall there was a 20% reduction in vehicles exceeding the newly posted limit of 80mph. While raising the speed limit reduces the number of drivers exceeding the speed limit, overall the actual speed that vehicles are traveling also increases.

Research has turned up mixed results.Īlmost anyone will notice that on any road, that the average driver is often driving up to 5 miles above the speed limit. This has led to intense debate over whether or not raising the speed limit has made the roads safer or more dangerous. In the past few years, states have been raising their speed limit levels on a lot of their highways.
