Expert Insights: Rumors can have a ring of truth
Rumors have a strange way of persisting in the transportation industry. The one thing I’ve learned about rumors surrounding DOT safety regulations is that even the strangest among them can have a ring of truth and merit some investigation.
For example, the old rumor that sleeper berths need white sheets is clearly false, but the rules do require each berth to be fitted with “adequate bedclothing and blankets.”
The rumor that drivers can log off duty to reach a “safe haven” is also false, but the rules do allow drivers hauling explosives to go off duty if parked in a specific type of safe haven or if eligible to drive on personal conveyance.
Even enforcement officers aren’t immune
The latest rumor I heard got its start with DOT inspectors who were warning drivers for not applying their reflective tape properly. The rumor is that the alternating red-and-white tape on the side of a trailer must start with a certain color at one end, and end with a certain color at the other.
Like most rumors, this one seems to have a ring of truth — and upon further investigation it actually does have a toe in the regulations, though it’s hard to find.
According to 49 CFR 393.11(b), reflective tape on the side of a large trailer has to comply with the DOT manufacturing standards in 571.108. Within there, the section that talks about taping the side of a trailer makes no mention of starting with a specific color. The red-and-white tape has to reach as close as possible to each end of the trailer and cover at least half the trailer length.
Does that put the rumor to rest? Not quite.
Look elsewhere in those standards and you’ll find certain specs for all alternating red and white tape, including these:
- White tape cannot be closer than 3 inches to a red or amber lamp, and
- Red tape cannot be closer than 3 inches to an amber lamp but can be close to a red lamp.
The side of a standard trailer has a red lamp near the rear and amber lamps at the front and mid-point. Put these requirements together and — lo and behold — you can see how the rumor evolved. Starting with red tape at the rear makes the most sense because red tape can be placed close to a red lamp, but white cannot.
Starting with red at the rear is not required — which means our rumor is still just a rumor, but it does carry that ring of truth. So the next time you hear a “tall tale” that you think cannot possibly be true, take some time to investigate. It may hold just enough truth to be a legitimate concern. Either way, you’re likely to learn something along the way to finding the truth.
