When toll prices increased between 25 percent and 50 percent in October, the number of New Hampshire residents who signed up for an E-ZPass transponder soared, too. The transponder allows motorists to drive through specially designated lanes at tolls, saving them time - and 30 percent on the toll charge.
About 2,500 new accounts were opened in October, said Bill Boynton, public information officer for the New Hampshire Department of Transportation. That's 40 percent higher than the average number of accounts opened every other month last year.
It was the largest spike in transponder sales the state has seen since the device was introduced to New Hampshire drivers in the summer of 2005, he said. That summer, 79,500 E-ZPass accounts were opened, partially because of a six-week introductory deal that allowed residents to purchase a transponder for $5. Transponders now cost just under $25.
David Ingalls of Kingston is one of thousands of E-ZPass users from Southern New Hampshire. He said his only regret about opening an account with his wife a year and a half ago is that he didn't do it sooner. "We should've gotten it when they first started, because they were cheaper then," he said.
And since many share Ingalls' sentiments about saving money, the state's E-ZPass office knew October's toll increases would affect sales, said John Corcoran, E-ZPass program manager for New Hampshire.
"We were prepared," he said. "We thought there might be a spike in open accounts, so we ordered more transponders."
The state didn't run out of the devices, but did sell more in October than in any other month for the past two years.
Now, E-ZPass traffic is at an all-time high in the state. Before the toll increase, about 51 percent of motorists who passed through the tolls each week used an E-ZPass. In recent weeks, that number has grown to 58 percent, the highest Boynton said he's ever seen.
And Corcoran said that 58 percent is right in line with 11 other states, including Maine, Massachusetts and New York.
"Some states are lower (than New Hampshire) and some are a little higher and reach the 60s (percent)," he said. "But remember, we've only been (using E-Z Pass on the roads) for two and a half years; some have been doing this for five years."
