PHILADELPHIA (CBS) - Police in parts of Center City and South Philadelphia have been giving written warnings to bicyclists who refuse to follow the rules of the road. Starting Labor Day, they’ll start writing tickets.

Lieutenant Ray Evers explains why the Captain of the 3rd District instructed officers to issue warnings to cyclists.

“Third district is a very large district. It covers to the Southern portion of Center City and Society Hill. He saw an uptick of some of the issues and felt it was important to be aggressive.”

Chief of staff of the Mayor’s Office of Transportation and Utilities Andrew Stober says there’s a good reason for law enforcement to take this stand because there are so many cyclists.

“There are more then 10,000 Philadelphians who choose to get to work regularly by bike.”

Steffie is a cyclist.

“I think it’s good for safety, but as far as bicyclists, I think they know the way of the road for the most part. I think Philadelphia should install more bike lanes.”

Steffie also wishes drivers would be more attentive to the road rules too.
