NSLS ESH Highlight #38

Following BNL Bicycling Regulations

Date: June 15, 2005
Editor: N. Gmür, G. Van Derlaske

All bicyclists must follow the New York State traffic laws while riding a bicycle on BNL property:

  • Wear a bicycle helmet: it is Laboratory policy for all cyclists on-site. The bicycle helmet must conform to the Consumer Product Safety Commission (CPSC) Bicycle Helmet Standard. Note: All helmets issued off-the-shelf from Property & Procurement Management conform to this standard. Only staff who ride Laboratory-owned bicycles are issued these helmets. Staff riding their own bicycles must purchase their own helmets.
  • Ride in the same direction as the flow of traffic; keep right where practicable to allow vehicles to pass.
  • Ride in a straight line and single file.
  • Stop at stop signs and red lights.
  • Use a light, reflectors, and reflective clothing during darkness.
  • Wear bright clothing during the daytime.
  • Ride to the right if you are moving slower than other traffic, unless you are turning left, passing another bicycle or vehicle, or avoiding hazards.
  • Use proper hand signals when turning, stopping, or changing lanes.


  • Use extra caution when it is raining, and allow extra time to stop.
  • Cross railroad tracks at a right angle to the tracks.
  • Walk your bike when using a crosswalk.
  • Do not wear headphones on both ears while riding.
  • Keep your bike properly maintained so it is safe.
  • Do not drink and ride.
  • Ride defensively.
  • Be alert for road hazards.
  • Watch for cars at cross streets and driveways.
  • Obey all traffic signals.
  • Keep a safe distance from parked cars and watch for car doors that may open.
  • Give pedestrians the right-of-way.

Failure to follow these regulations may result in a citation being issued for a traffic violation and in disciplinary action. See the SBMS section Issuing Traffic Citations for more information.

Bicycle Helmets

Whether you cycle around the BNL site for business or pleasure, the BNL bicycle-safety policy notes that you must wear a bicycle helmet and that the helmet must conform to the Consumer Product Safety Commission (CPSC) standard. For those using BNL-issued bicycles, helmets meeting the CPSC standard can be ordered fromlab inventory. The helmets are sized as follows:

K-70300 - small/medium (fits 20-3/8" to 22-7/8")
K-70302 - medium/large (fits 21-1/2" to 24-3/4")
K-70304 - large/extra large (fits 22-3/4" to 24-3/8")

Note: Bicycle helmets are a restricted-inventory item, so you must be authorized by the NSLS ESH Coordinator or Building Manager to order one through the PeopleSoft pick-ticket system.
