2024 New York Cdl DMV Practice Test #1

When driving a large commercial vehicle on a steep downhill grade, it is crucial to engage the engine brake (if equipped) and maintain a constant, controlled speed to prevent the vehicle from gaining excessive speed and risking loss of control.

Using the brake pedal lightly and intermittently can lead to brake overheating and loss of braking effectiveness, especially on a steep grade.

Increasing speed on a downhill grade can lead to loss of control and potentially cause a runaway vehicle situation.

Shifting to neutral and coasting down the hill is extremely dangerous, as it eliminates engine braking and reduces the driver's ability to control the vehicle.
