Question Analysis
The Texas DPS Driver Handbook states that a safe following distance depends on speed. For speeds above 30 mph, drivers should maintain a minimum following distance of four seconds. This rule provides enough time to react and brake if the vehicle ahead stops suddenly. The handbook emphasizes that at higher speeds, a greater following distance is necessary because stopping distance increases significantly.
Correct Answer Analysis
Correct Answer: Four seconds.
Four seconds is correct because the Texas DPS Driver Handbook specifically requires a minimum following distance of four seconds when driving faster than 30 mph. This allows adequate time for perception, reaction, and braking at higher speeds.
Wrong Options Analysis
Option: One second.
One second is far too short for speeds above 30 mph. It does not provide enough time to react to sudden changes in traffic, and the Texas DPS handbook does not recommend this for higher speeds.
Option: Two seconds.
Two seconds is the minimum following distance recommended for speeds of 30 mph or below, not for speeds faster than 30 mph. At higher speeds, two seconds is insufficient for safe stopping.
Option: Three seconds.
Three seconds is a common following distance rule in some states, but the Texas DPS Driver Handbook specifies four seconds for speeds above 30 mph. Three seconds does not meet the Texas requirement for higher speeds.
