Wont accept your drivers license if theres a crack, of any magnitude. This is not stated anywhere on their policy, and caused me to lose two hours of drive time. I fly with this license, I rent elsewhere with it, and I registered to vote with it. Yet Alamo refused to accept it. The only reason Im offering three stars is due to the boss. After jumping hoops to speak with the overseeing managers, I finally reached the boss. He was very understanding and stated that an email was sent out by the Houston PD stating they have to accept these, even if theyre taped. Problem solved. I had my car within two minutes.
