What is the purpose of an escape ramp?

An escape ramp is specifically designed for vehicles to safely stop in the event of brake failure, especially in situations where trucks are descending steep grades. These ramps are constructed with a sloped design and often filled with gravel or other materials that create friction, helping to bring a runaway vehicle to a halt without causing serious injury or damage.

This safety feature is crucial for heavy vehicles that can experience significant issues with braking, particularly when carrying heavy loads. If a driver finds they cannot stop their vehicle due to brake failure, making use of an escape ramp is a critical safety maneuver. The design and purpose of escape ramps directly address the need for additional safety measures on steep roads, contrasting sharply with the other options which do not pertain to the primary function of these ramps.
