Tips for Securing Your Load
Tie it Down
Large or heavy items should be firmly secured with solid straps, rope, bungee cords, or netting. Tie large items directly to your vehicle. Tied down materials must be able to withstand wind up to 70 miles per hour on the highway. At that speed, the wind is providing about a 20-pound-per-square-foot push, which can dislodge those loads and push them off your vehicle. Do not use restraints if they are frayed, cut, or damaged. Tie large objects directly to your vehicle or trailer.
Cover it Up
For loose, lighter items such as tree clippings, a sturdy plastic or canvas tarp or netting can be used to keep items in place. Tie the tarp securely or it might become road debris as well.
Lighter Goes Lower
Put lighter weight things at the bottom of the load and make sure they are secure. Evenly distribute the load to prevent it from sliding.
Do Not Overload
Keep material level with truck bed or trailer unless tied down, netted or under a tarp.
Double-check your load to make sure it is secure at the back and on the sides and top. Remember that loads can move and settle during a journey, allowing restraints to loosen. If possible, recheck restraints shortly after beginning your trip.
Make Sure It's Roadworthy
Ensure both the vehicle and trailer are in good mechanical condition and roadworthy. Check that your vehicle is rated to tow the load. Remember that your load will make your vehicle less maneuverable and it will take longer to stop.
Is there any chance of debris falling or blowing out of my vehicle? Would I feel safe if I were driving behind my vehicle? What would happen to my load if I had to brake suddenly or if I hit a bump?
