What is the purpose of an escape ramp?

To allow vehicles to park during long trips
To enable vehicles having braking problems to stop safely
To assist vehicles making sharp turns
To provide a rest area for drivers

The correct answer is: To enable vehicles having braking problems to stop safely

The purpose of an escape ramp is to enable vehicles that are experiencing braking problems to stop safely. Escape ramps are specially designed to provide a safe area for vehicles, especially larger ones like trucks that may lose their brakes while descending steep grades. These ramps are typically made of gravel or sand and are positioned at strategic points along the roadway. They help slow down and bring vehicles to a stop without causing crashes or accidents, thereby protecting the safety of the driver and others on the road. The other options do not accurately describe the function of an escape ramp. Parking areas and rest areas are designed for resting or taking breaks but do not provide the safety measures necessary for vehicles in distress. Similarly, escape ramps are not intended for assisting in sharp turns; they serve a specific function related to braking issues rather than maneuverability on the roadway.
