The Two Second Rule...

1. Step 1

   The first step in determining the safe distance between your vehicle and the vehicle in front of you is to notice the objects that the vehicle in front of you is passing. Example: Notice when the vehicle passes a lamp post or a fire hydrant or parked car, etc.

2. Step 2

   As soon as the vehicle passes that parked car, start counting one thousand one, one thousand two, one thousand three, etc.

3. Step 3

   If you have passed that same car before you two seconds have gone by, then you are too close to the vehicle in front of you.

4. Step 4

   If you passed that same car after two seconds have gone by, then you are at a safe distance from the vehicle in front of you.

5. Step 5

   You'll notice that the safe distance actually is shorter when driving at slower speeds and increases when you're driving at higher speeds.
