New rules take effect Sunday for Chicago taxi drivers and passengers.
Cab drivers are now restricted to 12-hour work days, while cab companies must keep more detailed records of their drivers, including schedules and violations on the road.
Passengers will see a few changes, including an extra $1 surcharge and a $50 fee if a rider vomits in the vehicle.
Some cabbies are threatening to strike during Monday rush hour until the city council approves a fare increase to cover new expenses.
