Georgia DDA 6-Hour Defensive Driver & Driver Improvement Practice Exam

Maintaining an interval of at least 3 full seconds (5 is even better) is the correct approach to determine if you are following another vehicle too closely on the highway. This method allows for a safe following distance, taking into account the speed of your vehicle and the traffic conditions. The 3-second rule provides adequate time to react if the vehicle ahead suddenly slows down or comes to a stop. If you can count three seconds from the moment the vehicle in front of you passes a fixed point until your vehicle reaches that same point, you are likely maintaining a safe distance. Additionally, increasing that interval to 5 seconds can provide even more time to react, enhancing safety on the road. The other options do not provide a reliable or safe method for determining following distance. Simply leaving 50 feet may not be sufficient in all situations, especially at higher speeds. Staying close enough to read the license plate does not consider the need for a safe stopping distance, potentially leading to dangerous situations. Attempting to pass another vehicle to avoid the question of following distance could create more risks and hazards than simply maintaining a safe distance from the vehicle in front.
