Bicycle Safety and Operations

Protect Your Investment - Wear a Helmet

  • Reduce your risk of head injury by 85%.
  • When adjusting your helmet, remember to check your:


You should be able to fit two fingers between your eyebrow and helmet.


Side straps need to join right below your earlobes.


Chin straps should be snug, with room for only one finger.

Be Visible At Night

Bicycle lights and reflectors are required by law after dark to ensure that you remain visible to other cyclists, pedestrians, and vehicles.

  • Wear high-visibility clothing - Add reflective gear to your clothing to increase your ability to be seen by others.
  • Add lights - Lights increase your visibility to others and allow you to safely see the road ahead of you.  Flashing front, rear, and ankle lights have the added benefit of attracting more attention than static lights for passing vehicles.
  • Maintain your bike reflectors and add reflective tape - While most bikes already come equipped with reflective surfaces, you can add reflective tape to your helmet, bike, rims, and pedals for added safety.


Bike Light Giveaways

To support safe bike riding at night, UCI Transportation offers the opportunity to receive free bike lights.  The Be Visible campaign occurs after daylight saving ends each year and lasts until all available lights have been claimed.


Obey Signage and Signals

  • Obey traffic laws - Cyclists are required to stop at traffic lights, stop signs, and yield signs.
  • Watch for pedestrians - Use caution when approaching pedestrian crossings and stop if there is a stop sign.


Use Hand Signals

  • Hand signals tell everyone what you intend to do.
  • Signal as a matter of law, courtesy, and self-protection.


Follow General Bike Safety Procedures

  • Only Ride in designated bike lanes – shared pathways are marked and cyclists should use the appropriate bike lane whenever possible.
  • Ride single-file - Ride in a straight line about a car door's width away from the parked cars.
  • Pass with caution – Only pass on the left and alert the people around you. Say "On your left" as you are about to pass.
  • 3 feet law - When riding next to cars, allow 3 feet of space between your handlebars and the edge of the vehicle's side-view mirror.
  • Ride at a safe, reasonable speed - Consider the flow of bicycle traffic and other bike path conditions.
  • Don't weave between cars - Avoid riding to the curb between parked cars. Motorists may not see you when you try to move back into traffic.
  • Follow lane markings - Don't turn left from the right lane. Don't go straight in a lane marked "right turn only"; stay to the left of the right turn only lane if you are going straight
  • Choose the best way to turn left - There are two ways to make a left turn:
    • Like a motorist: Signal move into the left lane, and turn left. In a left turn only lane, stay to the right of the lane to allow any motorists behind to make their turn on your left.
    • Like a pedestrian: Ride straight across to the far-side crosswalk, dismount, and walk your bike across.
  • Whenever possible, avoid travel during peak travel times - Congestion occurs during the change of classes. You'll find the bike paths enjoyably empty during class time.

Bike Operation

Bicycling on sidewalks is prohibited on the University campus except in those few areas where no parallel roadway or bike path exists. Bicycles at UCI may not be operated on any landscaped areas, pedestrian corridor, pedestrian ramp, or anywhere signs are posted prohibiting bike riding.

Bicyclists must obey all posted speed limits. Additionally, no cyclist may travel at a speed greater than is reasonable and prudent under existing conditions. At the University, the speed limit on campus bike paths is 8mph.

Operating a bike while under the influence of alcohol or drugs is punishable by fines, jail time and/or loss of driving privileges.

It is also illegal for two persons to ride on a bike meant for one or to have earphones covering both ears while cycling.
