Driver's License Test Prep
Florida Practice Lane Changes & Merging

You are on the acceleration lane of a Florida limited access highway. When should you merge into traffic?

  1. A.
    Only after coming to a complete stop at the end of the acceleration lane
  2. B.
    As soon as your signal is on, regardless of the gap in traffic
  3. C.
    Immediately, because highway traffic must yield to entering drivers
  4. D.
    When you can do so safely, yielding to traffic on the highway Correct
The Why

The answer is "When you can do so safely, yielding to traffic on the highway"

Florida's four-step procedure has you check for an opening on the ramp, signal, build speed in the acceleration lane, then merge only when there is a safe gap while yielding to the traffic already on the highway. Drivers who picture the on-ramp as a ramp meter, as if the entrance itself grants right of way, pick C and hand priority to the entering car.

Why the others miss

The traps in the wrong answers

A. Only after coming to a complete stop at the end of the acceleration lane

The acceleration lane is built for gaining speed and merging, not for a routine stop at its end; you stop there only when traffic is too heavy and there is no safe gap. Treats the end of the acceleration lane as a hard stop line, carrying over a yield-sign habit from surface streets.

B. As soon as your signal is on, regardless of the gap in traffic

A signal announces intent but does not create a safe gap; the merge still has to be safe. Reads the turn signal as a claim on the right-of-way, a habit picked up in slow city traffic where drivers wave a signaled car in.

C. Immediately, because highway traffic must yield to entering drivers

The yield direction is reversed; entering drivers yield to highway traffic, not the other way around. Flips the yield direction, picturing the on-ramp as a ramp meter that grants entering drivers priority.
