What does the Solid White Lines mean?
Solid white lines indicate you should not change lanes, such as near intersections, in tunnels, or in high-occupancy vehicle (HOV) lanes. You must not cross into an HOV lane at a solid white line.
In British Columbia, drivers are required to understand and respond correctly to the Solid White Lines at all times. Failure to comply with regulatory signs can result in fines or collisions.
Is this sign on the ICBC knowledge test?
Yes — the Solid White Lines is commonly tested on the BC ICBC knowledge test. Drivers must know its meaning, correct shape, colour, and the proper response when encountering it on the road. Road signs make up approximately 25–30% of the ICBC knowledge test, making them one of the most important categories to study.
BC Driving Test Tip
Solid white lines mean lane changes are discouraged or prohibited. HOV lane entry is only permitted at broken white lines.
