TMZ has obtained the 911 tape from Britney Spears' tour bus escapade -- when she was pulled over in San Diego for "disturbing traffic" on the way to last week's House of Blues mini-show.

The truck driver who made the 911 call suspected it was Britney's entourage and even knew she was playing a "secret show" that night!

Truckers heart Britney.
