Report Jalisco Driving Guide in Mexico General Posted April 12, 2011 Just an observation: I have found it far more persuasive to have with me the entire code of traffic laws for whatever state I am traveling through (they are not all the same). If there is English, the polic disregard it. All of the traffic laws are available in each state's website. While Spencers rulebook is mega-helpful (English and Spanish) it is not persuasive to ruarl policemen. If you have the rules of the road of whatever state, it really stops the police in their tracks.
