Delivery cyclists are facing new rules of the road today.

The city Department of Transportation has updated the laws for commercial bicyclists in an effort to make the streets safer.

Under the new rules, commercial cyclists must wear reflective vests and bicycle helmets.

They must also carry a business ID card at all times.

Business owners must supply all of these items.

They must also make sure bikes are equipped with a bell, lights, brakes, reflectors and a sign showing the business name and bike ID number.

Violators face fines from $100 to $250.
