ការបន្លឺសញ្ញាសូរស័ព្ទ ត្រូវប្រើក្នុងរយៈពេលខ្លី គឺមិនយូរជាងការចាំបាច់ឡើយ ។

In plain language

When using your horn, keep it brief and only sound it for as long as absolutely necessary.

3. The sound of horn has to be used in short time, but not in long time more than the necessary need.

A quick tap is usually enough. Prolonged honking can be considered aggressive and is against the rules.

Common confusion: Some drivers might hold the horn down, but the rule states it should be short.
