On streets with a right-side dedicated transit lane that accommodates a moderate volume of right-turn movements, the transit lane can permit right turns approaching an intersection.
On streets with a right-turn lane but no transit lane, buses can be permitted to use the right-turn lane for through-movements.
At locations where right-turning vehicles can typically clear through the intersection quickly.
Can accommodate moderate right-turn volumes at intersections where right turn on red is permitted and pedestrian volumes are low.
Can be applied to streets with or without dedicated transit lanes.
Shared transit/right-turn lanes allow vehicles to make right turns across a transit lane.
The operational benefits of permitting right turns from transit lanes accrue entirely to right-turning motor vehicles.
Where driver compliance is very low, permitting right turns from the transit lane may sometimes be safer than prohibiting turns.
If vehicle right-turn volumes are high enough for right-turn queues to occur with regularity, right turns should be accommodated separately from transit in a turn pocket.
The left-side line of the transit lane should be dashed for 50–100 feet in advance of the intersection.
Mark pavement with right-turn arrow. Install Right Lane Must Turn RighT and Except Buses signs (MUTCD R3-7R & R3-1B).
Install BUS ONLY signs and markings on the receiving side of the intersection.
Solid transit lane striping should drop to dashed striping 50–100 feet in advance of the intersection.
If provided as a shared right-turn/queue jump, a protected right-turn signal may be used, with a sign indicating RIGHT TURN SIGNAL (MUTCD R10-10) and EXCEPT BUSES. EXCEPT BICYCLES signs may also be provided.
Transit signals may be used to indicate when transit proceeds and when general traffic proceeds for both buses and rail vehicles.
On streets without bus lanes, a shared transit/right-turn lane can be provided to the right of general traffic through-lanes.
