Curbside Bus Lanes

Curbside bus lanes are located along the right side of the road next to the curb. By giving buses their own space along the curb, these lanes help reduce delays and allow buses to move faster through busy areas. Moving buses out of mixed traffic also helps smooth traffic flow in the general traffic lanes.

The way curbside bus lanes operate can vary depending on the street. Signs, traffic signals, and pavement markings show when vehicles can or cannot enter the lane. 

Curbside bus lanes are located along the side of the road where parking and deliveries have traditionally taken place. These lanes are for buses only—drivers should not stop, park, or drive in them. Use signed loading areas or nearby side streets for deliveries, passenger pick-up, and drop-off. 

Understanding bus lane markings

Image
A solid white line and diamond symbol means the bus lane is reserved for buses and authorized vehicles. Drivers cannot enter the lane or make a right turn across it. Drivers should continue to the next location where a right turn is permitted.

Bus lanes are identified using signs, pavement markings, diamond symbols, and red pavement in some locations. These features help drivers understand where buses have priority and where vehicles may or may not travel.

White lines show when vehicles can enter or cross a bus lane.

Solid white line and diamond symbol

A solid white line and diamond symbol means the bus lane is reserved for buses and authorized vehicles. Drivers cannot enter the lane or make a right turn across it. Drivers should continue to the next location where a right turn is permitted.

Dashed white line

A dashed white line shows where vehicles can cross the bus lane for permitted movements. Only enter the bus lane where the dashed line begins and when it is safe to do so. 


Turning right when driving

A dashed white line indicates that vehicles are permitted to cross the transit lane to enter or exit driveways or to access a right-hand turning lane.

There are two common ways right turns work:

Shared right-turn lane 

At some locations, drivers and buses share the same lane to complete a right turn. Drivers can enter where the dashed line begins and turn right.

Crossing the bus lane to reach a right-turn lane

In other locations, drivers need to cross the bus lane to reach a right-turn lane. Drivers can only cross where the bus lane changes to a dashed line.

Bus lane signs

Signs help guide all road users and show how to safely navigate rapid transit corridors.

Bus-only lane sign

A bus-only lane sign shows that a lane is reserved for buses and authorized vehicles. Drivers and cyclists should stay out of the bus lane and not stop, park, or drive in it.

This sign shows that a lane is reserved for buses and authorized vehicles.

Drivers should:

  • Stay out of the bus lane unless signs or pavement markings allow access.
  • Do not stop, park, or drive in the lane.
  • Follow all signs, signals, and pavement markings.

Keeping bus lanes clear helps buses move reliably. 

Bus and bicycle lane sign

This sign shows that a lane is shared by buses and people cycling.

  • Buses and cyclists may use the lane where permitted.
  • All users should remain aware of each other and travel safely.
  • The shared design supports multiple ways of travelling through the corridor.

Blank-out signs

Some intersections use digital blank-out signs to manage turns across bus lanes.

These signs can turn on or off depending on traffic signal phase.  When displayed, drivers must follow the restriction shown on the sign.

Frequently asked questions

Can I use the bus lane if an emergency vehicle is approaching?

Yes. If an emergency vehicle is approaching from behind with its lights and sirens activated, safely move to the right to allow it to pass (even if that means briefly entering the bus lane).

Emergency vehicles always have priority. Return to your lane as soon as it is safe to do so.

When the bus lane is marked with a dashed line, how do I enter a driveway?

A dashed white line shows where you can cross the bus lane to enter or exit a driveway.

Wait until the dashed line begins, check for buses and other road users, signal your turn, and cross the lane when it is safe to do so.

Do not drive along the bus lane before turning. Cross the lane only at the dashed section and complete your turn into the driveway.

Can I bike in a curbside bus lane?

Look for the white regulatory signs that show whether the lane is reserved for buses only or buses and bicycles

Cycling is only permitted in curbside bus lanes where signs indicate it is allowed. Where cycling is permitted, the bus lane travels in the same direction as traffic and there are no dedicated cycling facilities nearby.

Vehicles that stop or park in a bus lane may receive a fine from by-law enforcement.

Keeping the lane clear helps buses move safely and on schedule.
