Question 1463 in the bank

What warning measures are installed in the driver’s compartment of a vehicle with a pneumatic braking system (air pressure)?

  1. Correct answer: Warning lamp, warning buzzer, and air pressure gauge.
  2. Red warning lamp in the middle of the dashboard.
  3. Warning lamp and emergency braking handle.
  4. Warning lamp and independent brake.

Why this is the answer

The correct answer in the official bank: Warning lamp, warning buzzer, and air pressure gauge.

In an air brake system, a drop in air pressure can weaken braking, so the driver must know about it at once. That is why the cab has a warning lamp, a warning buzzer and an air pressure gauge that shows the pressure at all times. An emergency braking handle or an independent brake are ways to brake, not warnings, and a red lamp alone is only part of the set.
