  • A Guard rail is a system designed to keep people or vehicles from (in most cases unintentionally) straying into dangerous or off-limits areas. In traffic engineering, a guard rail is used to prevent vehicles from veering off a road into oncoming traffic, crashing against solid objects (like a bridge pillar) or falling into a ravine. A secondary goal is to keep the vehicle upright while it is deflected along the guardrail. The latter goal is made more difficult by the fact that a guardrail of the best height for a car might not keep a truck from toppling over it, while a motorbike might slip under a higher-placed rail. In most cases, a guardrail would not actually be able to withstand the impact of a vehicle just by the strength of the individual posts in the area hit by the vehicle. Instead, the guardrail is effectively one strong band (long metal strips lashed together, steel cables) which transfers the sideways force of the veering car to multiple posts beyond the impact area or directly into a ground anchor at the end of the guard rail emplacement.
