Exclusive Lane
専用通行帯(せんようつうこうたい)
Meaning
A sign designating a lane reserved for specific vehicles (such as route buses). In principle, vehicles other than those designated may not use that lane.
Common mistake on the test
Unlike 'Priority Lane for Route Bus' (327-5), vehicles other than those designated may not, in principle, use an exclusive lane (a priority lane may be used if it is clear).
