NEW YORK (CBSNewYork) — New rules for bicycle delivery riders take effect Tuesday in New York City.

The new commercial bike law was approved in October after complaints about bikers speeding and weaving down sidewalks.

Commercial bicyclists are now required to carry an identification card and wear helmets and reflective upper body clothing with the business’ name and cyclist’s ID number on the back.

Businesses could be fined $100 or more if they fail to provide riders with helmets, headlights and bells.

Commercial bicyclists must also obey all traffic laws, including yielding to pedestrians, riding in the direction of traffic and stopping at all red lights and stop signs, among others, and must take a safety course.

In addition, the law beefs up enforcement, giving Department of Transportation agents the power to write tickets to riders in addition to police.
