What is the required standard for guardrails on Virginia highways?

The correct answer is that guardrails on Virginia highways must meet crash test standards set by the Federal Highway Administration. This standard is essential for ensuring the safety of motorists. Guardrails are critical safety features designed to prevent vehicles from leaving the roadway or colliding with obstacles. By adhering to federally established crash test standards, the effectiveness of guardrails in real-world scenarios is validated, meaning they are capable of absorbing impacts and redirecting vehicles safely.

Prioritizing safety through rigorous testing helps ensure that the materials and construction of the guardrails can withstand the forces they may encounter in a crash, thus minimizing injuries and fatalities. Ensuring compliance with these standards is fundamental to highway design and maintenance, making it a crucial aspect of public safety measures on the roads.
