Highway Water Barriers, in Winter?

Actually, that isn't water. Its gasoline, sometimes diesel. The barrels are storage for helping drivers who run out of gas on the highway. The empties simply need to be refilled, which is done on weekends at night so as to minimize the impact. Additionally, this is why you frequently see police near these barrels, they can keep their car running all day long but never need to leave. Tow trucks frequently pre-position themselves there for similar reasons.

don't believe me? Crack one open and fill up your tank. Let me know what happens.

Might want to wait til AFTER the cops leave before partaking in that....lot less explaining to do that way.

Around here they aren't filled. They are either empty or have a 50lb sand bag in the bottom.

Again, this is why Camaro5 is the best site on the internet. Where else would I learn all this. I know in Ohio they are filled with I.O.U.'s from the state. We can't afford sand, water, monkeys, or Jack Daniels.

So me and my cousin were thinking, what happens in the winter? Hitting a bunch of solid blocks of ice like that would not be good. If it was salt water, wouldn't it eventually separate and the water would still freeze? Do they fill them with some other kind of liquid?

gata love the cts in that movie though

I believe the ones that have water are kind of like antifreeze, radiator fluid. They have a salty electrolyte additive that raises the freezing point.
