Step-by-step explanation:
The most common modus operandi (MO) for a taxi robbery typically involves one or several passengers directing the driver to a secluded area, where they then use the threat of violence or actual violence to rob the driver. Sometimes robbers may hail the taxi normally and then threaten the driver during the ride or upon arrival at the destination. Taxicab drivers are trained to be aware of suspicious behavior and to employ safety measures such as security cameras, silent alarms, and GPS tracking to help prevent robberies or assist in apprehending the suspects.
