Hotshot Tie-Down Rules: How Many Straps a Load Needs

Key point: the federal minimum for any piece of hotshot freight is the larger of two numbers, a tiedown count set by the article's length and a strength total of half its weight, and a 40 ft load that isn't blocked at the front needs at least five tiedowns before weight even comes into it.

Hotshots haul flatbed freight, so they live under the same cargo securement rules as semi flatbeds: 49 CFR 393.100 through 393.136. There's no separate hotshot rule. This guide turns those sections into a chart you can print, a counter you can run on any load, and the commodity rules that come up most on hotshot decks.

The two numbers every load has to meet

1. Count by length (49 CFR 393.110). Set by how long the article is, and whether something blocks it from sliding forward.
2. Strength by weight (49 CFR 393.106(d)). The working load limits (WLL) of the tiedowns must add up to at least half the weight of the article or group of articles.

How a tiedown counts toward that strength total depends on how it's attached. A tiedown that goes from one side of the trailer, over the cargo, to the other side counts its full WLL. One that goes from the trailer to an anchor point on the cargo, or over the cargo and back to the same side, counts half.

Behind both sits a performance standard: the system has to hold the cargo against 0.8 g braking, 0.5 g rearward and 0.5 g sideways without breaking (49 CFR 393.102). Meeting the count and the WLL total is how most drivers show they meet it.

Minimum tiedowns by length

From 49 CFR 393.110(b): two tiedowns for an article longer than 10 ft, plus one for every 10 ft or fraction past the first 10. If the article is blocked against forward movement by a headerboard, bulkhead or other secured cargo, the minimum is one tiedown per 10 ft or fraction of its length. Machinery and fabricated structural items that need special fastening methods are exempt from the count, but still have to be secured adequately.

Working load limits: what your gear counts for

A tiedown's WLL is the lowest WLL of any part of it, the tensioner and the anchor point included (49 CFR 393.108). If the manufacturer marked it, use the marking. If not, the rule assigns these values:

Values from the tables in 49 CFR 393.108. Chain grades only count when the chain is marked with its grade; an unmarked chain is treated as Grade 30.

That's why marked gear pays for itself. A worn tag can drop a strap to the default value, and a strap with a cut, burn or knot can't be used at all (49 CFR 393.104).

Run it on your load

20 ft steel bundle, 16,000 lb, not blockedEXAMPLE

Count by length (over 10 ft, up to 20 ft)3

Strength needed (half of 16,000)8,000 lb

4 in straps, 5,400 lb marked WLL, over the top3 give 16,200 lb

Same straps hooked direct to the bundle (half credit)2,700 lb each, 3 needed

Minimum3 tiedowns

EXAMPLE load. With unmarked 2 in straps hooked direct, each would count for only 1,000 lb, and the same bundle would need eight.

Commodity rules hotshots run into

The general rules apply to everything, and these sections add to them for specific freight:

For equipment, the four tiedowns go as close as practical to the front and rear of the machine, or to tie-down points the maker built for the purpose. Buckets, blades and booms are lowered and secured, and an articulated loader is restrained so it can't bend in transit (49 CFR 393.130). Machines under 10,000 lb can follow the same section or the general rules.

Edge protection, knots and other details

• Edge protection is required wherever a tiedown would be cut or rubbed by the cargo (49 CFR 393.104(f)).
• No knots in tiedowns, and repairs only to the gear's standard or the maker's instructions.
• Adjustable in transit. Every tiedown has to be something you can tighten on the road; steel strapping is the exception (49 CFR 393.112).
• Rolling cargo needs chocks, wedges or a cradle that can't come loose (49 CFR 393.106(c)).
• Loose items like dunnage, tarps and spare straps have to be secured too.

When to recheck

Check the cargo and every tiedown within the first 50 miles of a trip. After that, recheck whenever you change duty status, or after 3 hours or 150 miles of driving, whichever comes first (49 CFR 392.9). Straps loosen as loads settle, especially lumber and bagged freight.

How this guide was put together

Every number on this page comes from the eCFR text of 49 CFR Parts 392 and 393, checked on October 26, 2026. The counter applies 393.110, 393.106(d) and 393.130 to one article at a time and its formulas are unit tested. We recheck the rules every year and whenever FMCSA amends Subpart I; the next scheduled review is October 2027.

The gear to carry is on our hotshot equipment list, and the daily walk-around is in the hotshot pre-trip checklist. For the freight that pays for the straps, see hotshot loads and hotshot contracts.
