What is another name for the emergency brake?

The term "emergency brake" is commonly referred to as the parking brake. This device is designed to keep the vehicle stationary when it is parked, preventing accidental movement. The parking brake is typically engaged manually and is particularly useful in situations where the primary braking system may fail.

While terms like "hand brake" are often used interchangeably with "emergency brake" in informal settings, the most widely accepted term in driver training and vehicle operation contexts is "parking brake." It underscores the function of the brake as a critical safety feature, especially when the vehicle is stationary.

The other options may refer to braking systems but do not appropriately specify the function of the emergency brake in keeping the vehicle secured in a parked position.
