Five Car lengths, but only if you are on your toes. It depends on how alert you are at the time and if you can see and monitor the tail lights of the chain gang a lot further ahead than the car in front of you. If you are behind a car and it hits a stopped dump truck - can you stop? If you are tired - give yourself a lot of stopping room.
Actually, 9 car lengths if using 2-second rule. If follow 3-second rule, you should keep 13 car length.

The stopping distance for a vehicle traveling at 30 mph is typically around 75 to 100 feet, depending on various factors such as road conditions, vehicle type, and driver reaction time. This distance includes both the reaction time distance and the braking distance. It's important for drivers to maintain a safe following distance to ensure they can stop in time.

Six car lengths is a good distance.
A safe following distance between cars when driving is typically recommended to be at least 3-4 car lengths.
A rearview mirror typically provides a field of view that extends approximately 200 feet behind the vehicle. The exact coverage can vary based on the mirror's size and angle, but it generally allows drivers to see approaching vehicles and obstacles within a safe distance. Proper adjustment ensures optimal visibility for safe driving.
Measuring safe cushion of space in seconds factors in both the speed of vehicles and reaction times of drivers, allowing for a standardized and more universal approach to determining safe following distances. This takes into consideration varying driving conditions and speeds, helping to ensure a safe distance between vehicles regardless of the specific situation.
at least ten feet away.

Driving at night with visibility of 300 feet can be safe, but it greatly depends on factors like speed, road conditions, and weather. If you can see well enough within that distance to react to obstacles or other vehicles, it may be manageable. However, at higher speeds, 300 feet may not provide enough time to stop or navigate safely. Always ensure your vehicle's headlights are functioning properly to maximize visibility.
