Florida Practice Warning Signs

A yellow diamond warning sign shows a car with wavy skid lines behind it. What does the Florida manual tell you to do?

Yellow diamond with a black border showing a black silhouette of a car with two wavy skid trails behind its rear wheels.
  1. A.
    Drive slowly in wet weather and avoid quick braking or sharp turns. Correct
  2. B.
    Turn on your high beams for a clearer view of the road.
  3. C.
    Shift down to a lower gear before the marked section.
  4. D.
    Pump the brakes to check traction before entering.
The Why

The answer is "Drive slowly in wet weather and avoid quick braking or sharp turns."

A slippery surface sign tells the driver to drive slowly in wet weather, avoid sudden acceleration or hard braking, and take turns at low speed. The tempting wrong answer is the shift-to-lower-gear response, because drivers pull that instruction from the neighboring hill and downgrade sign and apply it to any traction warning.

Why the others miss

The traps in the wrong answers

B. Turn on your high beams for a clearer view of the road.

The sign does not call for high beams and using them offers no traction benefit; it warns about wet-weather handling. This answer treats any low-visibility yellow diamond as a cue to brighten the headlights.

C. Shift down to a lower gear before the marked section.

Downshifting is the Hill/Downgrade instruction, not the response listed for a slippery surface warning. This answer borrows the downshift instruction from the hill sign for any traction hazard.

D. Pump the brakes to check traction before entering.

Pumping brakes is the conventional-brake emergency-stop technique, not a preventive step at a slippery-surface sign. This answer substitutes the conventional-brake skid recovery for the sign's plain wet-weather instruction.
