Anyone recall the word SLOW (in a yellow diamond sign) and REDUCED SPEED (in a regulatory rectangle)?
Have not seen either for a long time. Last time I saw a REDUCED SPEED sign might have been on I-95 approaching the Delaware Turnpike tolls before the barrier was reconstructed to allow for high-speed open-road tolling down the middle.
both are commonly found in Massachusetts. lots of SLOW signs in Boston.
a brief glance at the 1935 MUTCD shows that SLOW is absent.

REDUCED SPEED AHEAD is in the regulatory rectangle. I seem to recall REDUCED SPEED in a warning diamond. "SLOW" is covered by the MUTCD language that allows you to use any text on a warning sign.
I took a cursory look yesterday at all old MUTCDs from present version back through the 1971 edition, and could not find any images of either sign.
The use of "SLOW" on a warning sign never made any sense to me. What exactly is the "slow" I should be looking out for...?
EDIT: Clarified that I looked through the more recent versions, not the pre-1971 manuals.

I
definitely recall seeing REDUCED SPEED in a rectangle. Used to be found in Maryland, but were gone by the 1980's. As I suggested above, the last time I saw them was on the Delaware Turnpike, approaching the mainline barrier, but that was a few years ago.
Agreed regarding SLOW. The ones I recall had nothing else - just SLOW (might make sense to post a lower speed limit instead of a SLOW sign).

Never saw it in any (recent) MUTCD.

Slow-moving traffic, perhaps? "Congested Area" might make sense.
Pedestrians?
Bikes?
I agree with your point.
I am not especially in favor of either of them, but at one time they were rather common in some states.

You are right. REDUCED SPEED AHEAD was a white rectangle, though whether the sign was part of the Regulatory Series or Warning Series was debatable prior to December 16, 2009.
Mississippi uses these a lot

Massachusetts used to have a lot of these (in warning diamonds):
GO
CHILDREN
SLOW
Often with CHILDREN in a larger font.

Still has a lot of those. In fact there's a particularly ancient one on a side street adjacent to the bridge project I'm working on.
Reduced Speed Ahead as a regulatory sign (black on white rectangle) appeared in the MUTCD (R2-5a) from the 1971 edition until the 2003 edition. Beginning with the 2003 edition, the R2-5a regulatory sign has been replaced with the Advance Speed Zone warning sign (W3-5 series).

Thanks!
