Driver's License Test Prep
Pennsylvania Practice DUI & Impaired Driving

According to the manual, what happens when a driver combines drugs with alcohol?

  1. A.
    The risk of causing a crash is greatly increased Correct
  2. B.
    The body processes the alcohol more quickly
  3. C.
    Only prescription drug combinations pose a risk
  4. D.
    The drugs cancel out the alcohol's effects
The Why

The answer is "The risk of causing a crash is greatly increased"

The manual warns that combining drugs and alcohol increases the side effects and greatly raises crash risk; the two neither cancel out nor process faster. Anyone landing on D is applying the folk belief that a stimulant simply offsets a depressant, which the manual never endorses.

Why the others miss

The traps in the wrong answers

B. The body processes the alcohol more quickly

The manual says only time processes alcohol, and drugs do not speed that up. Confuses the coffee-and-shower myth with a drug interaction.

C. Only prescription drug combinations pose a risk

The manual warns about illegal, prescription, and over-the-counter drugs alike. Misreads the warning as narrowly limited to prescriptions.

D. The drugs cancel out the alcohol's effects

Nothing in the manual supports one substance neutralizing the other. Applies a folk belief that a stimulant offsets a depressant.
