Bicycle Safety  Bicyclist Safety

Pedaling around Berkeley Lab? You're being healthy, clean, economical, and having fun! But play it safe – bicycle riders are, by law, subject to the same laws as motorists. Obey the traffic signs, speed limits, signals, and lane markings. And don’t forget to yield
to pedestrians!

Motor-vehicle drivers: Remember to share the road with cyclists! They have as much right to the road as any car. Be careful when you open car doors, pull out of parking spaces, and make turns.
