*Product shall be accepted by the FHWA as meeting or exceeding the NCHRP 350 or MASH testing requirements. Installer shall assume all responsibility for proper application and adherence to the manufacturer's installation instructions. Flared Terminals require a wider (1:10 or flatter) approach area prior to, and downstream of the end terminal. Non-Energy Absorbing End Terminals should only be installed at locations where a runout area exists behind and downstream of the end terminal.
