A loose load isn’t just a ticket — it’s a roadway hazard and a CSA point magnet. Here’s the framework.
The Basic Rule
Per 49 CFR 393.100-136, cargo must be:
- Firmly immobilized
- Restrained from shifting in any direction
- Secured against working free during normal driving
The Working Load Limit Math
Total tiedown WLL must equal at least 50% of cargo weight. So 40,000 lbs of freight = 20,000 lbs of combined WLL.
Tiedown Counts by Length
| Cargo Length | Minimum Tiedowns |
|---|---|
| ≤ 5 ft, ≤ 1,100 lbs | 1 |
| ≤ 5 ft, > 1,100 lbs | 2 |
| 5-10 ft | 2 |
| > 10 ft | 2 + 1 per additional 10 ft |
Special Commodity Rules
The standard has 8 commodity-specific sections:
- Logs
- Dressed lumber
- Metal coils
- Paper rolls
- Concrete pipe
- Intermodal containers
- Vehicles (auto haulers)
- Heavy machinery
Pre-Trip and En-Route
- Inspect securement within first 50 miles
- Re-check every 3 hours or 150 miles
- Re-check after every duty change

- Insufficient tiedowns
- Damaged or worn straps
- Improper edge protection
- Cargo not blocked from forward shift
If it shifts, it’s on you. Strap it like your CDL depends on it — because it does.
