Catchfence

A catchfence is a safety barrier installed around racetracks to protect spectators from vehicles and debris that might leave the racing surface during an accident.

Typically constructed from chain-link fencing, steel cables, and support posts, catchfences are designed to absorb energy and contain crashes. When a car impacts the fence, the flexible structure stretches to gradually slow the vehicle while preventing it from reaching spectator areas.

Catchfences are most visible at high-speed oval tracks like Daytona and Indianapolis, where they stand several meters tall above concrete walls. While controversial due to potential driver injury when cars make contact with support posts, they remain essential safety features at most motorsport venues worldwide.
