2024 New York Cdl DMV Practice Test #6

Shifting into a higher gear does not help slow down the vehicle and may exacerbate the situation by allowing the vehicle to accelerate.

Pumping the brakes is ineffective if the brakes have failed and will not restore hydraulic pressure.

Applying the parking brake while the vehicle is in motion is dangerous and can lead to loss of control or skidding.

Downshift to a lower gear and use engine braking to slow down. If your commercial vehicle's brakes fail while driving downhill, downshifting to a lower gear engages engine braking, which can help slow down the vehicle and regain control.
