Sharing the Road with Bicycles and Motorcycles

When sharing the road with vulnerable road users or large vehicles, extra caution and understanding are necessary. Here’s how to safely and legally share the road:


🚴 Bicycles

  • Cyclists have most of the same rights and responsibilities as drivers
  • Typically ride on the right side of the lane, but may “take the lane” if it’s too narrow to share safely

✅ Passing Bicycles

  • To pass a bicyclist in the travel lane, change to another lane whenever you can — then return to your original lane
  • When you cannot change lanes, give at least 3 feet of space
  • If you cannot give 3 feet, do not pass until you can

🔄 Turning & Door Awareness

  • Check for bicycles before turning or opening car doors
  • Common crash: a car turning right cuts off a bike going straight in the bike lane — always look over your right shoulder
  • Bikes may be on sidewalks or crosswalks in some areas — treat them like pedestrians

🌙 Night Visibility

  • Bikes should have:
    • White headlight
    • Rear red reflector or red light
  • Be alert — some may not have lights

🏍️ Motorcycles

  • Smaller and harder to see — look twice before:
    • Changing lanes
    • Turning left
  • Many motorcycle crashes involve a car turning left into the rider’s path

⚠️ Lane Splitting

  • Legal in California
  • Motorcycles may ride between lanes in slow/stopped traffic
  • In heavy traffic:
    • Check mirrors before changing lanes or opening windows
    • Do not block motorcycles

🚗 Following Distance

  • Don’t follow motorcycles too closely:
    • They can stop faster than cars
    • A rear-end collision could be severely injurious or fatal

🚛 Trucks and Buses

🕳️ Blind Spots (“No-Zone”)

  • If you can’t see a truck’s mirrors, the driver can’t see you
  • Avoid lingering beside large trucks

🌀 Turns

  • Trucks make wide turns:
    • May swing left before turning right, and vice versa
  • Never squeeze between a turning truck and the curb

🛑 Stopping Distance

  • Trucks take longer to stop
  • Don’t cut them off
  • On hills, give extra space — they may roll back slightly when starting

🐢 Speed and Lane Use

  • Trucks often travel slower (55 mph limit) and must stay in right lanes on highways
  • If a truck is passing you, slow slightly to help them pass safely

🚌 Buses and Streetcars

  • Do not pass a stopped bus or streetcar on the side where passengers are boarding/exiting
  • If a bus is pulling back into traffic with its signal on:
    • Yield — this is required by law
  • Be aware of bus-only lanes in some cities

Sharing the road is about awareness, patience, and respect. Smaller vehicles are vulnerable, and large ones require space. Always drive defensively and courteously.
