¶ Terminal
Terminals are safety devices designed to reduce the damage done when a vehicle leaves the road. They include the caps on guardrails and other barriers EndTerminal, and free standing cushions placed in front of fixed hazards like signs and bridge supports CrashCushion. They also include unprotected barrier ends, defined as BluntEnd.
