¶ Turn Down
¶ Summary
Colloquially known as a Texas Twister this was a popular way of "safely" terminating all guardrail until it was discovered that it greatly increased the likelihood of rollover crashes.
It is still commonly used for the trailing or downstream end of a barrier on a divided road (e.g. an Interstate).
