With warmer weather around the corner, Davey said more drivers and motorcyclists will be traveling, leaving less room for error.Last year, the state experienced more motorcycle deaths than it had in two decades.Davey urged Granite Staters to slow down and think responsibly before getting behind the wheel."People should really drive in conformity with the law," Davey said.He also said drivers should put down their phones and wear seat belts to keep themselves and others on the road safe.
