How to stay safe when traveling by taxi
Book your cab in advance.
Generally speaking, you'll be safer if you plan your trips ahead of time and call and schedule a cab to pick you up at a set time rather than hailing a cab on the street. This is particularly important if you are a woman or if you are young.

Select from the following.
[A]. Licensed taxi services have dispatch numbers you can call to schedule your cab in advance. Ask the operator for the name or car number of the car that is scheduled to pick you up..
[B]. Taxis typically are operating for retail use and those that are not operating for a special business want to avoid those services. You don't want to be committing to using a cab with a driver you're not reasonably used to..
[C]. Taxi companies use the already existing arrangement to map cab locations in advance-meaning booking more than one cab in advance, depending on the hotel's policies and requirements. Search online to find this information and book your cab at least 20 minutes earlier..
[D]. Taxis are often crowded, and booking them will limit these crowds. Always book first to avoid additional baggage fees..
[A].
