Keep A Space Cushion Ahead
Most rear-end collisions
are caused by following too closely.
Many drivers don't
give themselves enough time and distance to react and avoid
a hazard by following too closely behind the vehicle in
front of them. When you are too close to the vehicle in
front of you, your ability to see obstacles is diminished
As described earlier,
use the "two second rule". This is also considered
a "space cushion". If you are traveling at night,
in poor driving conditions or at higher speeds use a four
second space cushion. Keep a larger space cushion ahead
during slippery driving conditions, when pulling a trailer
or carrying a heavy load since it will take longer to slow
or stop your vehicle in an emergency.
If you are following
too closely and someone merges into your lane, and "cuts"
in front of you, there will not be much time for you to
react and avoid a collision. If you keep a good space cushion
ahead, when someone merges into your lane, it will be less
likely you will be cut in front of.
