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

You are passing another vehicle on a Texas highway. What does the manual tell you to do about that driver's blind spot?

  1. A.
    Flash your headlights to alert them of your position
  2. B.
    Pass through it or slow so you are not in it Correct
  3. C.
    Slow down and keep pace with the vehicle you are passing
  4. D.
    Sound your horn if you must stay beside them
The Why

The answer is "Pass through it or slow so you are not in it"

When passing, either move through the blind spot or slow down out of it. Sitting alongside another driver where they cannot see you is exactly what the rule prevents. Choice C tempts drivers who read a courteous, matched pace as the safe move; the passing rule instead names that steady side-by-side position as the one to leave.

Why the others miss

The traps in the wrong answers

A. Flash your headlights to alert them of your position

Headlight flashing is not the blind-spot rule the manual names. This answer borrows a truck-passing courtesy signal used on long-haul routes, which is not part of the Texas passing rule for cars.

C. Slow down and keep pace with the vehicle you are passing

Matching pace holds you inside the blind spot the rule is meant to move you out of. This answer reads a courteous match of speed as the safe move, an instinct from single-lane driving that puts you in the danger zone here.

D. Sound your horn if you must stay beside them

Sounding the horn does not replace the two moves the manual names for a blind spot: pass through it, or slow so you are not in it. This answer reads the passing chapter's 'tap your horn when necessary' tip as license to stay beside the other driver instead of clearing the blind spot.
