New flatbed drivers underestimate tarping. They pull tarps out in a 20 mph crosswind. They throw them over loads with sharp corners. They leave gaps on the back edge and find out about it two exits later when the tarp is flapping at 70 mph. A torn tarp is a $300 mistake, and re-tarping a loaded flatbed on the side of the highway is two hours you'll never get back. Here's the workflow that experienced drivers follow every time.
Before You Start
Setup determines whether the job goes clean or sideways:
- Check wind speed and direction. If it's gusting over 25 mph, wait. Tarping in high wind is how drivers get pulled off trailers and how tarps get ripped before they're even secured.
- Position the truck correctly. Park so the wind blows from cab toward rear — away from you as you work. This means the tarp blows away from you as you unfold, not into your face and off the load.
- Gear up: Gloves (tarp grommets and straps cut bare hands), your bungees, and corner protectors for any sharp edges on the load.
Step 1 — Position the Tarp on Top of the Load
Carry or drag the folded tarp to the top of the load — don't try to throw it from the ground. Stack it near the front edge, with the bottom hem of the tarp toward the front of the truck. You'll unroll toward the rear.
Keep the tarp folded until you're ready to deploy. An open tarp in any wind is already halfway off the trailer.
Step 2 — Protect Sharp Edges Before the Tarp Touches Them
This step comes before the tarp goes down, not after. Every sharp corner, every protruding bolt head, every rough metal edge on the load needs to be padded before the tarp makes contact.
- Use cardboard folded over corners for light edges
- Use plastic or steel corner protectors for harder edges
- Use foam pipe wrap or rubber matting for continuous sharp surfaces
A tarp touching an unprotected steel corner under vibration at highway speed will be ripped within 50 miles. The padding costs a dollar. The tarp costs $300.
Step 3 — Drop the Tarp Evenly
Walk the tarp backward from the front edge, letting it fall evenly on both sides of the load as you go. Don't throw it and don't yank it — throwing a tarp creates uneven tension on the grommets and can start a tear at the hem before it's even deployed.
Work in sections: unfold two or three feet at a time, let it settle on both sides, then continue toward the rear. A second person on the opposite side makes this significantly faster and cleaner.
Step 4 — Tighten from Front to Back, Then Sides
Once the tarp is laid over the load, pull out slack in this order:
- Front edge — pull down and forward, hook the front grommets to the front of the trailer or use bungees to anchor
- Rear edge — pull tight toward the back, remove all slack in the center panel
- Sides — pull down on both sides evenly, working from front to rear
Pull firmly but don't yank hard on individual grommets. Grommets are the most common failure point on tarps — they tear out when pulled unevenly under high force. Steady, even tension is what you want.
Step 5 — Bungee Down the Perimeter
Use heavy-duty 21" or 31" rubber bungees to secure the tarp hem to the trailer. Hook to D-rings, rub-rails, stake pocket tops, or dedicated tarp strap hooks — not to the tarp loops themselves if wind load will be significant.
- Space bungees every 2–3 feet along each side
- Don't overstretch — a 21" bungee stretched to 30" is past its working range and will snap the hook
- Double-hook on corners where wind pressure concentrates
Step 6 — Check the Wind Skirts
The "wind skirt" is the drop of tarp below the load bed level on each side. It matters:
- The skirt should reach below the trailer frame on all four sides, or as specified by your customer or the load requirements
- On short loads, tuck the rear skirt under the load if possible to prevent it from catching wind
- On loads that end well before the rear of the trailer, make sure the trailing edge is anchored — don't let it flap free
Step 7 — Final Walk-Around Before Pulling Out
Walk every side of the trailer before you move. You're looking for:
- Gaps where corners of the load are exposed
- Loose bungees that didn't catch their anchor properly
- Any section of tarp that's sitting on an unprotected edge
- Rear skirt not secured — the most common place drivers miss
Fix it now, in the yard, in two minutes. Not on the highway shoulder.
What to Avoid
- Tarping in winds over 25 mph: The tarp becomes a sail. You become a problem. Wait it out.
- Tarping over wet cargo: Moisture trapped under a tarp promotes mold on organic freight (lumber, paper, agricultural loads). Let wet cargo dry before tarping if time allows.
- Using bungees that are too short: Overstretched bungees snap hooks at speed. Match cord length to anchor distance.
- Leaving tarp flaps loose: A loose tarp edge at highway speed creates lift force that pulls the tarp free and can tear grommets out in seconds. Every edge gets anchored before you move.
- Skipping corner protection: This is the single most common cause of tarp damage on steel and machinery loads. Pad every edge, every time.
