Show the correct answer
Correct answer
B. The emergency brake lever is pulled up.
Explanation
In the photo you can see the instrument panel of a tractor with several red warning lights; the red arrow points to the warning light with the letter P in a circle surrounded by arcs. When this warning light is on, it tells you that the emergency brake lever, that is, the parking brake lever, is applied - answer B.
The letter P (from the English word "parking") in a circle with arcs on the sides is the international symbol of the parking brake. The warning light is on when the lever is applied, to remind you to release it before moving off. Driving with the brake applied overheats the linings and the drums or discs, which weakens the brakes exactly when they will be most needed, and in addition it increases fuel consumption. Tyre pressure (answer A) is shown by a completely different symbol - a cross-section of a tyre with an exclamation mark, and more often in cars than in tractors. The rear axle lock (answer C) is shown by a symbol of an axle with the differential marked. Before you move off, check that all the red warning lights have gone out.
