Alberta Class 7 License Practice Test

A white diamond marking in your lane is designed to communicate specific restrictions or privileges regarding the use of that lane. In the context of road signage and markings, the presence of a white diamond typically indicates that the lane is reserved for certain types of vehicles, such as high-occupancy vehicles, buses, or designated vehicle types depending on local regulations. This marking serves to inform drivers that they should not occupy this lane unless they meet the specified criteria, ensuring that traffic flow is maintained for vehicles that are allowed in that space.

It’s important to recognize that the other options describe different scenarios that do not align with the meaning of the white diamond marking. For instance, while some lanes might be for shared use or have specific turning restrictions, those scenarios are indicated with different types of markings or signage. Understanding the significance of road markings, such as the white diamond, helps promote safer driving practices and ensures compliance with roadway rules.
