Texas DMV Written Driving Practice Test

The correct answer is B because signaling your intention to stop 20 feet before the stop allows drivers behind you enough time to react and make necessary adjustments. Option A (10 feet) may be too close and not give enough warning, while options C (30 feet) and D (40 feet) may be excessive and could potentially confuse or distract other drivers. It is also important to note that in some states or driving situations, the recommended distance for signaling a stop may vary.
