If load is 5ft or shorter, 1,100 lbs or lighter:
Minimum number of tiedowns: 1
-
If load is 5ft or shorter, over 1,100 lbs:
Minimum number of tiedowns: 2
-
If load is more than 5ft but less than 10ft:
Minimum number of tiedowns: 2
- 1 tiedown for every 5 ft, or part thereof.
- 1 tiedown for every 10 ft, or part thereof.
- 2 tiedowns for every 10 ft, or part thereof.
- 1 tiedown for every 15 ft, or part thereof.
From The CDL Manual
When cargo is prevented from forward movement (for example, by the headboard, bulkhead, other cargo, or tiedown), secure the cargo according to the following requirements:
All Cargo:
1 tiedown for every 10 ft, or part thereof.
- Between 45 and 60 degrees.
- 90 degrees.
- It doesn't matter.
- Less than 45 degrees.
From The CDL Manual
The angle where the tiedown attaches to the vehicle should be shallow, not deep (ideally less than 45).
- Set the cargo on friction mats.
- Use some kind of blocking.
- Attach tiedowns to the cargo.
- Put something heavy on top of the cargo.
From The CDL Manual
What should you use in low-friction situations?
When there is low friction between the cargo and the deck (for example, with snow, ice, sand, gravel, and oil):
- Use tiedowns attached to the cargo.
- Use a means to improve the friction such as friction mats or tiedown that pass over the cargo.
- Use blocking and tiedowns.
- 100% of cargo weight.
- 80% of cargo weight.
- 20% of cargo weight.
- 50% of cargo weight.
From The CDL Manual
