[Alberta's Child]

I haven't had this problem in years. I drive a pickup truck with an extended cab and reverse-opening rear doors, and I usually have an empty bottle or coffee cup handy in the cab. When nature calls and I'm nowhere near a bathroom, I use this strategy:

1. Pull off onto the shoulder or a quiet parking lot

2. Venture over to the passenger side of the vehicle and open both the front and rear doors.

3. Use the makeshift "porta-john" to shield myself from public view while taking care of business.

4. Empty the cup or bottle in the grass before driving away.

JUST DON”T USE BEER CONTAINER, OPEN CONTAINER LAW WILL get YOU into trouble

That’s what I’ve thought of doing. Privacy with those doors open.
