Under what condition may you drive in the breakdown lane?

Driving in the breakdown lane is permitted during times of heavy traffic when indicated by signs. These specific conditions facilitate the smooth flow of traffic and help alleviate congestion, allowing vehicles to bypass slow-moving or stopped traffic. It is crucial for drivers to be aware that this is not a free-for-all privilege, and the permission to use the breakdown lane is dependent on signage indicating such allowances.

In contrast, using the breakdown lane during emergencies is not a blanket rule that allows for routine driving there; it serves a specific purpose for emergency vehicles or situations. Being allowed to drive at any time in the breakdown lane disregards safety measures and proper use of the lane, as it could endanger stopped vehicles or emergency situations occurring in that space. Finally, driving in the breakdown lane simply because there are no other cars on the road does not align with traffic laws that govern proper driving behavior, which prioritize safety and designated roadways.
