In addition to your "everyday carry" of a good tool kit and spare parts for your car, the following may be helpful in an evacuation, or post-disaster, especially if you are forced by unforeseen circumstances to take some bad or unimproved routes in a regular, non 4x4 off-road-ready car. You can do amazing things in a regular car, provided that you go slow, plan ahead and can accept significant damage or total loss and abandonment of the car:

- gas cans (very dangerous-emergency carry only)
- spare water/coolant
- full size spare, or two, mounted on rims (post disaster, there are lots of nails and other tire-shredding debris on the roads)
- Tow strap

For improvised off-roading:

- "Hi-Lift" jack (an amazing tool, for more than changing tires)
- Come-along with accessories and lots of chain or rope
- Shovel, axe, bow or chain saw, sledgehammer, hacksaw
- Carpet strips or other traction devices
- bolt and wire cutters (for gates and fences - only very extreme circumstances justify using these to access private property - try to minimize your damage. But public property like forestry roads may be gated or fenced off, too)
- The longest pry bar you can carry
- 2x4 and 4x4 wood pieces for cribbing
- Gazeteer or topographic maps
