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

Before you change lanes on a Florida highway, how does the manual say to check your blind spots?

  1. A.
    Tap the brakes to see how nearby drivers react
  2. B.
    Rely on your rear-view and side mirrors alone
  3. C.
    Watch the backup camera display briefly
  4. D.
    Turn your head to make sure the areas are clear Correct
The Why

The answer is "Turn your head to make sure the areas are clear"

Blind spots sit at the rear corners of the vehicle where mirrors and peripheral vision fail, so the manual tells you to turn your head and look before every lane change or pass. Newer drivers pick up in empty parking lots the habit that a properly adjusted mirror is a full solution, and that shortcut leads straight to B.

Why the others miss

The traps in the wrong answers

A. Tap the brakes to see how nearby drivers react

Brake taps are not a blind-spot check and would surprise following drivers. This answer borrows the 'flash your brakes at a tailgater' habit and misapplies it to a lane-change decision.

B. Rely on your rear-view and side mirrors alone

The manual defines blind spots as areas the mirrors cannot show, which is why a head check is required. This answer treats a properly adjusted mirror as a full solution, a shortcut newer drivers pick up in empty parking-lot practice.

C. Watch the backup camera display briefly

Backup cameras face the rear, not the side blind spots that matter for lane changes. This answer extends the backup camera's role forward, assuming a camera solves any visibility problem.
