Mystery Warning Signs...Meaning?
« on: May 18, 2015, 04:37:44 PM »

I drive by these signs on SB I-5 south of Bellingham everyday, and I cannot figure out what message they are conveying.

Ideas?

Last time I came back from Canada, those caught my eye. I've been looking for the answer for several weeks, but I haven't come up with anything.

Literally, it seems to convey that "those with trailers should use caution ahead, as the road dips to the right and you might lose control".

Tsunamis may pick up cars with trailers and drop them off in about 1.5 mi

OR Tsunamis may pick up cars with trailers for the next 1.5 mi

It looks like a wave I think.  :-P

Cars with trailers will hover over the road.

Next 1.5 Miles.

Downhill ahead = potential for runaway trailers if your car sucks

Warning: Slow cars pulling trailers blocking both lanes causing you to lose your mind because you can't pass them next 1.5 miles ?

Warning: Do not use your trailer-car combo as a surfboard on top of a medium-sized wave for the next 15 miles.  :clap:

Jokes aside, is there any official answer? I assume it's somewhere between "runaway trailer" and "losing control".

Noofficial answer. Just guessing that it tries to describe the incline, and that such incline will be tricky ifyou're in a car with a trailer, for the next 1.5m.

Not to get too OT, but the show ended when Robert Stack died. :)

It's a Washington specific alternative to sign W1-13 Truck Rollover.  Compare to New Jersey's propensity for nonstandard "ROTARY" signs for traffic circles and roundabouts.

I always assumed it meant that either the road wasn't banked, was banked wrong, or was banked for higher speeds than trailers usually travel, letting those drivers know to be careful incase their trailers start behaving oddly.

They said take a left at the fork in the road.  I didn't think they literally meant a fork, until plain as day, there was a fork sticking out of the road at a junction.

Essentially, yes.  It's been a very long time since I was up through there on highway (usually took Amtrak Cascades as it's faster and gets through the border without the hellacious wait at Peace Arch International Park), but I seem to recall at least one visibly off camber and relatively sharp curve through there.  The speed limit's 50 or 55 with good reason through there; there's a couple curves you can't take at that speed as it is.

The posted speed limit is 60 through there.  It might be difficult for a topheavy vehicle, especially if there's ice, which there easily might be.

I've never seen a sign quite like that, but I bet you are on the right track with your guesses.  Fyi, the term describing the degree of cross slope banking is "superelevation".  Use that term to properly affirm your road-geek-ness!    :-D
