M'madera omwe ngozi za magalimoto zimachitika kawirikawiri, zotchingira zachitsulo zokhazikika panjira (MBGRs) zimakhala zodula kwambiri kuzikonza. Kuphatikiza apo, anthu ammudzi ndi mabungwe akupempha Caltrans kuti ayike zotchingira za m'mbali mwa msewu zokongola pamisewu yayikulu zomwe sizingaikidwe ndi zotchingira zachitsulo zokhazikika. Mapulojekiti ena omanga misewu akhala akuchedwa chifukwa cha mawonekedwe osawoneka bwino a zotchingira. Zotchingira zambiri zokongola ndizopangidwa ndi anthu ndipo zimakhala zodula kuzimanga ndi kuzisamalira. Caltrans ikupanga zotchingira zachitsulo zosakonzedwa bwino (ALMGRs) zomwe sizimakonzedwa bwino komanso zokongola m'maso.
Cholinga cha kafukufukuyu chinali kupanga ndi kuyesa njira yatsopano yotetezera yomwe ikugwirizana ndi malangizo a American Association of State Highway and Transportation Officials (AASHTO) Guide to Assessing Safety Equipment (MASH) Level 3 (TL-3) a mayeso a ngozi. Njira yotetezera ikakwaniritsa zofunikira ku California pa zotetezera zokongola ndipo idzatha kupirira kugundana kwa magalimoto popanda kuwonongeka kwakukulu kapena kutayika konse. Idzakhala ndi mtengo wotsika wa moyo, idzakhala ndi zigawo zochepa zosungiramo zinthu, komanso yosavuta kukonza kapena kusintha ngati pakufunika kutero. Kafukufukuyu adagawidwa m'magawo atatu. Gawo loyamba linali kupanga ndi kuyesa maziko a konkriti omwe angagwiritsidwe ntchito ngati njira yotetezera mogwirizana ndi chotchinga chokongola cha mlatho. Gawo lachiwiri likanapanga ndikupanga njira zatsopano zotetezera zomwe zikugwirizana ndi zosowa za ku California zomwe zafotokozedwa pamwambapa. Gawo lachitatu likanapanga ndikuyesa njira zatsopano zotetezera zomwe zidapangidwa mu Gawo lachiwiri.
Pa Okutobala 16, 2013, Gulu Lofufuza za Chitetezo cha Msewu (RSRG) linayesa MASH 3-11 pa chotchinga cha mlatho cha ST-10 chomwe chinayikidwa pa maziko a konkire okwana mainchesi 762 (762 mm) ndi mainchesi 508 (508 mm) m'lifupi. Pofuna kutsanzira momwe zinthu zinalili zovuta kwambiri, chotchingacho chinayikidwa mu dothi lofewa ndi malo otsetsereka a 3 mpaka 1 omwe anakumbidwa kumbuyo kwa chotchingacho. Malo otsetserekawo ayenera kuyamba mamita 914 kuchokera m'mphepete mwa kumbuyo kwa maziko a konkire ndipo ayenera kukhala ofanana ndi kuya kwa maziko. Mazikowo anathiridwa m'magawo awiri; kuthira koyamba kunali kwa maziko ndipo kuthira kwachiwiri kunali kwa malo otsetsereka a mainchesi 152 (152 mm). Kuthira kumeneku kumapanga malo ozizira pakati pa maziko ndi malo otsetsereka. Galimotoyo, galimoto yonyamula zitseko zinayi ya Dodge Ram 1500 ya 2006, inagunda chotchingacho pa liwiro la madigiri 99.8 pa ngodya ya madigiri 24.7. Kuphatikiza kwa chotchinga cha mlatho wa ST-10 ndi maziko a ngalande kunasintha njira yoyendera galimoto yoyesera popanda kuyenda kwambiri kupita ku maziko. Komabe, galimotoyo itataya kukhudzana ndi chotchingacho, inagubuduzika. Ngakhale kuphatikiza kumeneku sikunakwaniritse zofunikira zowunikira za MASH (F), maziko a ngalandewo adachita monga momwe anafunira. Chifukwa chake, mtundu uwu wa maziko a ngalande umalimbikitsidwa pakupanga chilichonse chotchinga cha mlatho chomwe chikukwaniritsa miyezo ya NCHRP Report 350 kapena MASH Test Level 3 kapena 4. Kuphatikiza kwa zotchinga/maziko kumeneku kungaganizidwe kuti kugwiritsidwe ntchito ngati zotchinga za TL-3 pamisewu ya California.
