Florida Practice Road Markings

Your two-lane road is divided by double solid yellow lines. Which action does Florida permit across those lines?

Two parallel solid yellow lines running lengthwise down the center of a dark roadway.
  1. A.
    Pass a slow car ahead when the road is clear.
  2. B.
    Make a U-turn whenever oncoming traffic is stopped.
  3. C.
    Turn left across the lines when it is safe. Correct
  4. D.
    Overtake a farm vehicle traveling below 25 MPH.
The Why

The answer is "Turn left across the lines when it is safe."

Florida permits crossing a double solid yellow line to turn left when it is safe; ordinary passing of another motor vehicle across the line is not allowed. Option B stretches this left-turn exception into a U-turn allowance on the assumption that a U-turn is just a wider left the rule ought to cover.

Why the others miss

The traps in the wrong answers

A. Pass a slow car ahead when the road is clear.

Passing another motor vehicle across double solid yellow lines is prohibited even when the road ahead looks clear. This answer applies the broken-yellow 'pass when safe' rule to a double solid yellow center line, treating a clear view ahead as license to cross.

B. Make a U-turn whenever oncoming traffic is stopped.

The double-yellow left-turn exception does not authorize a U-turn, and stopped oncoming traffic does not create a separate U-turn permission. This answer stretches the left-turn exception into a U-turn allowance on the assumption that a U-turn is just a wider left turn the rule ought to cover.

D. Overtake a farm vehicle traveling below 25 MPH.

Slow-moving vehicles do not create an exception to Florida's double-yellow rule. This answer carries over a slow-moving-vehicle passing rule from rural states that let drivers cross a double yellow to get around farm equipment below 25 MPH.
