You may want to include a vehicle repair kit. My car kit includes:

• Basic tools
• Reflectors
• Gloves, roll of towels
• Gas can (empty)
• Tire wrench
• Air foot pump
• Portable battery jump starter pak
• Jumper cables
• Spare fuses, Duct tape, Wire, Extra hose clamps, Tire repair kit (as well as keeping up the air pressure in the spare tire)
• I thought about adding a quart of oil and a quart of windshield washer fluid but haven't gotten around to that yet.

Let's face it, if I can't repair my vehicle with these basic items then the repairs are simply beyond my ability and a call for service is required!

I also carry my hard hat, hi-vis vest, hearing and eye protection, and work boots due to my job requirements.
