Best answered in Yahoo... Their question was:
' A "Restricted Lane Ahead" Sign with a diamond shaped-marking on it means:? ' (clip)
Diamond lanes are typically buses-only, streetcars-only, or sometimes bus and carpool. If you have a chance to qualify, there will be signs saying the requirements and hours.
Read carefully -- California has several types:
- Buses only.

- Buses and carpools only certain hours, otherwise anyone
- Buses and carpools only. Ever.
And then carpools are sometimes 2 and sometimes 3 people.
Confusing eh?
