Learners generally know "don't drive in the emergency lane," but the exceptions and the exact conditions for pulling into one are where the real test happens.
Here is one worth locking in:
Besides a vehicle breakdown, when else is a driver permitted to use the emergency lane?
Permitted uses generally include allowing emergency vehicles to pass, or when directed to do so by traffic police or road signage, not for skipping congestion or making up time. Treating the emergency lane as a "free lane" during a jam is one of the more clearly tested violations.
Beyond emergency lane use, this category also covers lane discipline near expressway exits, where late lane changes create some of the highest-risk scenarios on the road.
Your turn. If there is a lane rule you keep mixing up, post it here. If you know the answer to someone else's, help them out.
