In normal driving conditions, the ideal minimum interval between your car and the one following should be at least three seconds. This allows for sufficient stopping distance and reaction time in case of sudden stops or emergencies. To establish this gap, pick a fixed point on the road ahead, and count the seconds it takes for the car behind you to reach that point after you pass it. Adjust the distance as needed in adverse weather or traffic conditions.
