too closely reduces your ability to avoid a collision, so
if someone is tailgating you don't speed up and cause a
collision trap in front of you. It's
better to gradually slow and let the tailgater pass your
vehicle when it is safe to do so.
If you are in a situation
where you have to brake hard to avoid hitting a vehicle
in front of you. It's most important not to panic and be
used to the type of brake system your vehicle is equipped
with. If your car is equipped with anti-lock brakes press
hard on the pedal and you should be able to steer and control
your vehicle. If your vehicle doesn't have anti-lock brakes.
Brake hard, but not so much that you go into a skid and
possible loose control.
