Driver's License Test Prep
Pennsylvania Practice Speed Limits

The road is wet and visibility is poor. What does the manual say you must do about your speed?

  1. A.
    Keep going at the posted limit
  2. B.
    Speed up to clear the area quickly
  3. C.
    Drive below the posted speed limit Correct
  4. D.
    Match the flow of the fastest lane
The Why

The answer is "Drive below the posted speed limit"

Wet pavement or poor visibility means driving below the posted speed limit, since that posted number is the maximum only under ideal road, traffic, and weather conditions. Answer A reflects the habit of treating the posted number as a target speed regardless of what the road and weather are doing.

Why the others miss

The traps in the wrong answers

A. Keep going at the posted limit

The posted limit assumes ideal conditions; in rain the manual expects you to drive below it. This answer treats the posted number as a target speed regardless of what the road and weather are doing.

B. Speed up to clear the area quickly

Speeding up in poor visibility is the opposite of the manual's slow-down rule for wet or low-visibility roads. This answer falls back on a clear-the-danger-fast instinct instead of reducing speed for the conditions.

D. Match the flow of the fastest lane

The manual tells you to slow for conditions, not to match the fastest lane on the road. This answer applies the go-with-the-flow-of-traffic rule of thumb for open highways to a rainy, low-visibility situation.
