When transporting a load of logs that are not contained within a bunk or cradle, what is the minimum number of tiedowns required for a single log that is 25 feet long?
- A3 tiedowns
- B2 tiedowns
- C5 tiedowns
- D4 tiedowns
Show answer & explanationAnswer & explanation
Correct answer: A. 3 tiedowns
For logs transported without bunks or cradles, the FMCSA regulations (393.116) specify that each log must be secured by at least two tiedowns. Additionally, if the log is longer than 10 feet, it must have at least two tiedowns, and if it's longer than 20 feet, it requires at least three tiedowns. A 25-foot log falls into the 'longer than 20 feet' category, requiring a minimum of three tiedowns.
Why the other options are wrong
- B. Too few. Two tiedowns are for logs up to 20 feet long.
- C. Incorrect. This number is not specified for a single log of this length.
- D. Incorrect. Four tiedowns are not specifically mandated for a single 25-foot log unless it's part of a larger, stacked load.
Securing Logs (No Bunks)
Specific FMCSA rules dictate the minimum number of tiedowns for logs not contained in bunks, based on log length.
- Logs 10 feet or less: 2 tiedowns.
- Logs 10 to 20 feet: 2 tiedowns.
- Logs over 20 feet: 3 tiedowns.
- Tiedowns must be placed to prevent rolling and shifting.
Memory trick: Short logs get two, long logs need three, keep them from rolling, wild and free!
