Of all the space around your vehicle, it is the area ahead of the
vehicle — the space you’re driving into — that is most important.
The Need for Space Ahead.
You need space ahead in case you must stop suddenly. According
to accident reports, the vehicle that trucks and buses most often
run into is the one in front of them. The most frequent cause is
following too closely. Remember, if the vehicle ahead of you is
smaller than yours, it can probably stop faster than you can. Following
too closely causes accidents.
