Per law, bicycles must possess a license (a UCPD sticker affixed to your bicycle). Additionally, to use some secure bicycle parking areas on campus and at residence halls, you must have a license (UCPD sticker) on your bicycle.
UCPD offers bike licensing services for free. You will need to bring your bicycle to 1 Sproul Hall between 6pm to 9pm, Monday-Friday.
Contact UCPD if you have questions.
