'They Shouldn't Be Transporting Passengers': Federal Government Warns Hollywood 'Topless' Tour Van Operators

The federal government is now investigating one of the most famous tours in the world because of an NBC4 investigation. The I-Team series documented potential safety hazards of Hollywood tour buses, including showing how some seatbelts have been modified or removed altogether. The series also looked at how the buses have been customized so that they are "topless," leading experts and officials to question their ability to protect passengers in the event of an accident.

The United States Department of Transportation has mailed certified letters to more than two dozen tour bus companies stating it believes the convertible tour buses lining Hollywood Boulevard are not safe and should not be taking passengers anywhere.
