Why should you limit the use of your horn according to the Drivers Manual?
A. It can startle other drivers. B. On vehicles with air brakes, it can use air pressure that may be needed to stop. C. The horn is not a good way to let others know you are there. D. You should keep both hands tightly gripping the steering wheel at all times.
Back in the 1950s, many drivers who went through a driver’s education course or received lessons from a prominent driving instructor would be taught to use your horn a lot. If someone was getting a letter out of their mailbox and barely stepped into the street, it was expected that a car passing by honk its horn to make sure that the man at the mailbox would not step into the street.
At the next corner, the new drive may be advised by the instructor to honk their horn at the intersection because the light was about to turn green and the driver should alert others that he is about to drive into the middle of the intersection. These may seem like great ideas, but nowadays, people would be annoyed and startled by the honking of the horn.
