Angry Guadalajara cab drivers staged a noisy protest outside the State Congress building Friday to demand tougher sanctions on drivers of private car companies, in particular Uber, who lack official operating permits.

The taxi drivers blocked streets with their yellow cabs for over an hour as they aired their grievances over the fierce competition that Uber and other firms now represent. 

Protestors shouted “Fuera Uber” (Uber Out), as they called on lawmakers to crack down on what they refer to as “pirate” taxis.

Representatives of the cab drivers later met with legislator Martin Lopez Cedillo, the head of Congress’ Transportation Committee, who promised to analyze the situation and see what steps can be taken to ensure laws are correctly applied. The taxi drivers say Uber cars that operate without permits should be removed from circulation rather than simply receive a fine.
