You are driving 25 mph on a Texas street with good road conditions. According to the manual, what is the minimum following interval behind the vehicle ahead of you?

Four seconds is the interval the manual sets for speeds above 30 mph and also recommends as best practice for a beginning or less experienced driver; the question asks for the minimum at 25 mph, which is 2 seconds. This answer reads the manual's line that a four-second following interval is the best practice for a beginning or less experienced driver as if it were the required minimum at every speed.

The manual warns that reaching a fixed object less than two seconds after the vehicle ahead means following too closely; one second sits inside that warning zone, below the 2-second minimum. This answer treats the 'following too closely' warning distance as an acceptable target instead of the boundary a driver must stay above.

Texas prints 2 seconds as the minimum at 30 mph or below with good conditions; three seconds is a common driver-education rule of thumb, not the figure the Texas manual uses. This answer carries the three-second following cushion taught in generic driver-education materials into a Texas answer, where the manual prints 2 seconds as the minimum at these speeds.
