Class D License
The Class D License examination has
20 questions and 20 road signs. Some of the test questions will
come from the list below; others will come from the Class E test questions in Chapter
5. You are allowed to miss not more than five questions and five
If you come upon an accident, activate
the Emergency Medical System (EMS) to insure prompt response. Then
apply four first aid rules:
- Protect yourself from possible injury or infection
- use barrier devices such as gloves and a mask.
- Start the breathing. If the injured person
has stopped breathing, start artificial respiration right away.
Do not stop until another qualified person relieves you or the
victim is breathing normally.
- Stop the bleeding. Most bleeding can
be stopped by pressing down on the wound. If possible you should
place a gauze pad, a clean cloth or even your fingers (if wearing
protective gloves) will have to be used. Bleeding from an artery
should always be stopped first. The blood from an artery will
be bright red and will come out of the wound in spurts. If the
blood is darker in color and flows evenly, it is from a vein.
Once the gauze or cloth is in place - DO NOT REMOVE IT.
- Treat for Shock. Persons who have
been injured may go into shock. When someone is in shock, all
of the body functions slow down. Shock can be very serious. It
can cause death. Shock may develop right after a crash or later.
Injured persons must be treated for shock regardless of whether
or not they appear to be in shock.
- Reassure the injured person. Your calmness
will help. Do not give them anything to drink.
- Cover the person with blankets or coats
to hold body heat. Have the person lie flat.
- Keep onlookers back so that the injured
person has air.
- Keep their head as low as possible unless
there is a head injury.
- Loosen tight collars to make breathing easier.
DO NOT MOVE AN INJURED PERSON
IF THE PERSON CANNOT MOVE OR COMPLAINS OF PAIN IN THE BACK OR
NECK OR HAS A HEAD INJURY.
DO NOT ATTEMPT TO REMOVE THE HELMET OF AN
INJURED MOTORCYCLE RIDER.
USE PRUDENT CARE AND GOOD JUDGEMENT. WORK ONLY WITHIN THE SCOPE
OF CARE YOU ARE TRAINED TO PROVIDE.
