It's often hard to get medical care on the road, so it's important to carry a personalized medical kit in the truck, both for your own health and for responding to emergencies.

You can buy a ready-made first aid kid, from basic to deluxe, but don't forget to take things for your own personal health.
If you already have a medical kit, take a few minutes to check and make sure it's fully stocked and that no medications have expired.
We spoke with a number of truckers, one of them a former EMT, and got their suggestions for what to pack:
Any current prescription medication you are taking
Pain reliever (such as aspirin, Tylenol, Advil)
Anti-diarrhea medication
Antacid
Antihistamine (for colds, allergies, bee stings)
Sterile saline solution (can be used to wash out eyes)
Chapstick
Hydrogen Peroxide
Antibacterial cream or ointment, such as Neosporin
Hydrocortisone/anti-itch cream
Something for sore muscles, such as Ben-Gay or Aspercreme
Wet towelettes
Ace bandage
Cold pack (the kind that doesn't need a freezer)
Tweezers (good for removing splinters)
Thermometer
Decongestant
Cough syrup or drops
Latex gloves (in case you stop to help with an emergency, to avoid contact with victims' body fluids)
Roll of gauze
Gauze pads
Band-Aids
Medical tape and scissors

Note: Read labels of over-the-counter medicines carefully. Antihistamines and many cold medications often can make you drowsy and should not be used when you need to drive. These medications, and cough syrups with lots of alcohol, have been known to result in citations for driving under the influence.
