The Texas Department of Public Safety’s Handbook for Texas Drivers advises the following procedure:

Passing on a Two Lane Road

1. Keep enough distance between you and the car in front of you so you can see ahead clearly. Check rearview and side mirrors and turn your head and look back—someone may be passing you. Signal left.

2. Check well ahead for “No Passing Zone” and oncoming cars. Be sure you have time and space enough to overtake the car ahead and return to the right lane before an approaching car comes within 200 feet of you.

3. Tap your horn when necessary to alert the driver ahead.

4. Pass on the left and do not return to the right lane until safely clear of overtaken vehicle. Wait until you can see the car you have just passed in your rearview mirror before returning to right lane.

5. Signal right turn to return to right lane. Be sure to turn your signal off after you have completed the lane change.
