SEATTLE — Roadside litter comes in all shapes and sizes — from dirty diapers to syringes — but there's one category that out-grosses the rest: trucker bombs.
Most drivers whiz along the nation's highways largely oblivious to their roadside surroundings. But next time you are out there, take a closer look.
"As soon as you look for it you’ll see it," says Megan Warfield, litter programs coordinator at Washington state's Department of Ecology. "You just see them glistening in the sun. It’s just gross."
They are trucker bombs, plastic jugs full of urine tossed by truckers, and even non-truckers, who refuse to make a proper potty stop to relieve themselves.
Disposing of trucker bombs, aka torpedoes or pee bottles, is a thankless task that in many cases falls to highway cleanup crews.
When it comes to human waste, the dangerous category covers trucker bombs and dirty diapers. Together the accounted for 8,000 pounds of trash collected from state roads last year.

In April, Colorado increased its "human waste" fine from $40 to $500. Transportation employees convinced lawmakers of the need for the drastic increase with their tales of finding urine jugs as they mowed roadway ditches. "We hit them, they explode. The operator ends up wearing this stuff," Randy Dobyns told state senators.

Dobyns estimated he picks up at least 50 containers a week, sometimes milk jugs, water bottles or even bags filled with urine. "The folks who dispose of this stuff are very creative in their use of containers," he said.

Well this is one American cultural practice that we don't need!
So when you see a truck stopped, and the driver "surveying" the off side rear wheel, just remember he is doing his thing for a clean and green New Zealand.........
