One car length for every 10 miles per hour of speed.
A safe distance, there is no defined limits of this type as driving near parked cars is situational (at best).
One car length for every 10 miles per hour.
Safe distance is 2 seconds, or 4 car lengths. More if snow is on the ground or its raining.
I always heard of the two second rule but I am not sure if that is law.
one car length per 10 miles per hour
it is recommende to keep a gap of at least two seconds behind the car in front of you so the distance varies with the speed
Be aware of your surroundings, reduce your speed, turn on the car's headlights and keep a safe distance between cars. If roads are starting to slip drop down a gear and do not brake use the engine to slow the vehicle
This is when you are driving in between two cars, one to the right and one to the left. You are in the middle and that is consider a "danger alley". This is not a safe position in a freeway.
Know your distance between cars, fire hydrants and railroad crossing. These are the most over looked.
