"Safe Drive Save Life"?

Solution 1:

In the advertising industry

(including the so-called social advertising)

they sometimes invent slogans which are grammatically incorrect because the slogan is a specific text ("a brief attention-getting phrase used in advertising or promotion"). (Sometimes the grammatical incorrectness can be explained by poor English.)

The slogan in question is a typical example of "headlinese or journalese style".

There are some common characteristics:

1. Using the infinitive instead of the finite form (save instead of saves).

2. Pseudo rhyming (driVE - liFE).

3. Alliteration (SAve - SAfe).
