The Motor City's cabbies must be able to speak English and know the geography if they want to continue to drive for hire.
A new set of regulations under consideration by the Detroit City Council include a dress code that forbids shorts, sleeveless shirts and slippers.The proposed guidelines call for cabdrivers to be U.S. citizens or holders of green cards allowing them to work in the country.
"We've been pushed by the public for cleaner, better cars, and for drivers who don't look scruffy, who talk to their passengers in English and who know their way around," said Consumer Affairs Director Esther Shapiro.
The city's 1,300 cabs would have to be well-maintained under the regulations that will be introduced Wednesday.
The council also will consider a new designation covering luxury sedans, described as six-passenger vehicles that are less than 2 years old and are hired by the hour.
