The NGT brings errant vehicles, from small cars to pickups, to a controlled stop for end-on impacts up to 15°, and its length of need begins at Post 2, only 6'-3\" (1.9 m) from the first post. This gives road designers more flexibility where hazards, slopes or limited space sit close to the end of the guardrail.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy non-gating\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eConventional gating terminals decelerate vehicles that hit the end at approx. ±3°. At larger angles the vehicle gates behind the guardrail at speed and can travel approx. 150 ft (46 m), into the very hazards the guardrail is meant to shield. Their length of need starts 12-18 ft (3.7-5.5 m) from the end, they depend on a traversable clear zone behind the barrier, and the rail can spear into the vehicle.\u003c\/p\u003e\u003cp\u003e85% of off-road terminal crashes occur at angles of 15° or less, and the NGT stops them. US FARS data from 2018 shows approx. 1,000 fatal crashes involving a guardrail impact, approx. 250 of them with the most harmful event behind the barrier: a fixed object, a slope, water or a rollover. For the US, non-gating terminals are estimated to save 200+ lives per year against a societal cost of USD 2.36 billion annually (fatalities only); replacing every terminal in the US within one year would still give a benefit-cost ratio above 1.0.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003eStops end-on impacts up to 15° instead of approx. ±3°\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eLength of need from 6'-3\" (1.9 m) instead of 12-18 ft\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eLess clear zone and earthwork needed behind the barrier\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eNo spearing\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eCrash tested at up to 77.5 mph (124.7 km\/h) against 62 mph for conventional terminals\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003eMASH 2016 TL-3 tested, all seven required tests passed (3-30, 3-31, 3-32, 3-33, 3-34, 3-35, 3-37b)\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eFHWA eligibility letter CC-178\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eNon-gating for end-on impacts up to 15°\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eLength of need from Post 2, 6'-3\" (1.9 m) from Post 1\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eHigh-speed testing within all MASH preferred criteria at up to 77.5 mph (124.7 km\/h)\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eTangent terminal, no offset required\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e8 unique part types, 22 parts in total excluding fasteners\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eInstalls with standard guardrail equipment in approx. 45 minutes or less\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eAnchor rail, shelf bracket and hardware may be reused after impact\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eTechnical data\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003cp\u003eTest standard: AASHTO MASH 2016, TL-3 (100 km\/h)\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eTerminal length: 37'-6\" (11.4 m), anchor post to Post 10\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003ePay length options: 37.5 ft (11.4 m), 40 ft (12.2 m), 50 ft (15.2 m)\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eCompatible guardrail: strong-post W-beam (MGS) with 8\" or 12\" blockouts\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eRail height: 31\" ± 1\" (787 ± 25 mm) above finished grade\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003ePost spacing: 6'-3\" (1.9 m) anchor post to Post 1 and Post 1 to Post 2; 3'-1.5\" (0.95 m) Posts 2-9\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003ePosts: galvanised steel, W6x9 plug-welded posts 1-9, W8x15 anchor post\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eImpact head: 8 ft x 14-13\/16\" x 20\" (2.44 m x 376 mm x 508 mm), approx. 91 kg\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eOffset \/ flare: no offset required; 1-2 ft straight flare over 50 ft recommended, max. 25:1\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003eConnection to rigid barriers via a stiffness transition\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eFields of application\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eGuardrail ends on high-speed roads where a vehicle gating through the terminal would reach a hazard: bodies of water, steep slopes, bridge piers, trees or other fixed objects close to the guardrail end, and locations with too little space for a conventional length of need.\u003c\/p\u003e","brand":"Nordic Traffic Safety","offers":[{"title":"Default Title","offer_id":53835603345744,"sku":"1316000030","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0932\/6395\/4256\/files\/1316000030_ngt_install.jpg?v=1792482030","url":"https:\/\/shop.nts.world\/products\/ngt-non-gating-w-beam-end-terminal-mash-tl-3-11-4m","provider":"Nordic Traffic Safety WebShop","version":"1.0","type":"link"}
