WATCH: ‘Dead Silent’ Tesla spotted hauling trailer

A Tesla semi truck prototype was recently spotted hauling a trailer along a highway in California, and witnesses are impressed. 

In the clip, what appears to be an original silver Semi prototype hauling a trailer can barely be heard over the excited shouts of the filming motorists. 

In fact, the electric rig prototype was apparently so silent, the motorists almost didn’t notice it, sort of like it snuck up on them. 

Check out the excited clip of the electric semi truck, below.
