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

You are driving in the middle lane of a Texas highway. A faster vehicle approaches from behind in that same lane. What does the manual say you should be prepared to do?

  1. A.
    Move to another lane to allow the faster vehicle to pass Correct
  2. B.
    Move over only if the driver behind signals or flashes their headlights
  3. C.
    Maintain your speed to keep the flow steady
  4. D.
    Speed up to match the vehicle behind you
The Why

The answer is "Move to another lane to allow the faster vehicle to pass"

Any lane except the right lane should be ready to move over and let faster traffic pass. Choice C is the trap for drivers who take the manual's "maintain a constant speed" rule as the whole rule for a highway lane, missing that a separate rule adds a duty to yield the lane when someone faster is behind you.

Why the others miss

The traps in the wrong answers

B. Move over only if the driver behind signals or flashes their headlights

The manual says to be prepared to move over; it does not condition your duty on the other driver signaling first. Adds a courtesy-driving custom the manual never requires: the move-over duty attaches to your lane position, not to whether the overtaking driver asks first.

C. Maintain your speed to keep the flow steady

Holding a steady speed is what the manual asks once you are settled in a lane; it is not a substitute for the separate rule that tells you to move over for faster traffic. Treats the constant-speed guidance as an override on the move-over rule, when the two apply to different situations.

D. Speed up to match the vehicle behind you

The manual does not tell drivers to speed up to keep another car from passing. Borrows the road-rage instinct of matching a tailgater's speed, which the manual treats as aggressive rather than defensive driving.
