During a reserved bus lane’s posted hours, which use by an ordinary car does SGI’s handbook permit?

Correct answer: Entering it to turn right onto or off the street block.

Why

Read the bus-lane sign’s days and hours. While the restriction applies, an ordinary car may enter for a right turn onto or off the street block, but may not use the lane to continue straight or pass traffic. Check carefully before crossing the lane. SGI gives separate rules for bicycle-only lanes; their parking and driveway exceptions should not be treated as blanket permission to stop in an active bus lane.
