On Monday, the first night of the program, officers stopped 22 violators.

Yesterday morning, CPD’s net caught Undergraduate Council President Rohit Chopra ’04.

A former bicycle messenger and a member of a Cambridge committee redesigning Harvard Square, Chopra said he was aware of the law and agreed that light-less biking was a danger.

But he said that biking in the Square was hazardous in general.

“There are no bike lanes, it’s becoming a unsafe place to bike,” Chopra said.

Another Harvard biker, Paul G. Dexter ’04, said that traffic, not lighting, is the most important threat to safety.

“The biggest safety concern is from the speed cars are going when there are no bike lanes,” Dexter said. “The danger from that is the greatest problem, in the day just as much as at night.”

Murphy stressed that it is important for students to exercise caution when biking around Harvard Square.

“If you’re riding a bike at night, purchase a light,” Murphy said. “Try to stay to the right of traffic and be careful of parked cars.”
