The correct answer to the question is:
C. Escape ramps
Escape ramps are found on steep downgrades and are designed to safely stop a runaway vehicle. These ramps provide a crucial safety feature for drivers facing brake failure or other emergencies while descending a steep grade. When a driver utilizes an escape ramp, it helps prevent accidents and potential injuries by offering a designated area where the vehicle can come to a controlled stop.
Escape ramps are strategically located on highways and roads with significant inclines to offer an escape route for vehicles experiencing difficulties maintaining speed or stopping due to mechanical failures or driver errors. These ramps typically consist of uphill sections filled with loose gravel or sand, which helps slow down and ultimately stop the vehicle safely.
In summary, escape ramps play a vital role in road safety by providing a dedicated space for runaway vehicles to come to a stop, reducing the risk of accidents and ensuring the well-being of drivers and other road users.
