Final answer:
To maintain safe driving conditions, it is important to keep a certain distance between your vehicle and the one in front of you based on the length of your vehicle.
Step-by-step explanation:
For each line of one foot of length in your vehicle, keep at least two seconds between you and the vehicle in front of you.
This is important for ensuring safe driving conditions and allowing enough time to react in case of any sudden changes or emergencies on the road.
For example, if your vehicle is 10 feet long, you should maintain a distance of at least 20 feet (or 6 meters) from the car in front of you.
