Air Rail Highway Bike/Ped Public Transit

Engineering standards involve the design and placement of signs. The main purpose of signing is to inform motorists of regulations such as speed limits and stops, warn them of any impending dangers such as sharp curves and steep grades, and help them find their destination by clearly marking routes and cross streets. Signs must be properly spaced so that motorists have time to perceive the information on signs and make the appropriate driving maneuver.

There is tremendous demand for signing along our highway system; many businesses, organizations and agencies feel that they need and deserve signing to advertise, inform and/or aid the motorist in locating their establishment. It is necessary to limit all signing to only that which is sufficient to aid drivers in safely arriving at their destination. As such, NHDOT and state law set out criteria that a facility must meet in order to be eligible for signing.
