Arkansas Driving Permit Practice Test

When driving at 55 mph, it is recommended to allow at least 10 seconds to pass another vehicle safely. This is because it takes time and distance for your vehicle to accelerate and move past the other vehicle, and you need enough time to judge the distance and make sure it is safe to change lanes. Options B, C, and D are incorrect because they all provide a shorter amount of time, which would not allow for a safe passing distance. It is important to follow the recommended time for passing to ensure the safety of yourself and other drivers on the road.
