This highway sign is pure mathematical genius! It cleverly transforms the classic "don't drink and drive" PSA into a calculus pun by showing "d/dt" (the notation for derivatives) in a prohibited circle with "NEVER DRINK AND DERIVE" alongside it. The derivative operator is what we use to find rates of change—but your ability to find those rates might change dramatically after a few drinks! Solving for the limit as sobriety approaches zero is definitely not recommended for your GPA or your driving record. The function of your brain with respect to time becomes rather discontinuous when alcohol enters the equation!
