Hi Folks, This question is very "Specific"... Doesn't appear to

me that this question has anything to do with a person with a load

in their vehicle or how to mark it, how many feet the load extends

past the tailgate, etc... The "Real" and "Accurate Answer" to this

question is a definite "YES".. In California you are allowed to

drive your Pick-Up Truck with the Tail-Gate Down... Anything else

that you do with your Vehicle, Trucks or otherwise of course

"Common Sense" applies here... Thanks and Have A Good Day


No. If you have supplies in the back of your truck that extend a

few feet past your taillights, you will need to flag the end of the

supplies. If you are just trying to save on fuel by driving with

your tailgate down, you may want to look up the TV show

Mythbusters. They tested 2 of the same trucks, driving down the

same road at the same speed, with the same weight driver... and the

truck with the tailgate up got better gas mileage. Air travels over

the cab and across the bed without going into the bed. Lowering the

tailgate created a vortex in the bed of the truck, which caused

more turbulence.
