This question tests basic knowledge of right-of-way rules at uncontrolled intersections, which are common in residential areas. In Canada BC, like in many places, when two vehicles arrive at the same time at an uncontrolled intersection, the driver on the left must yield to the driver on the right. This is a standard rule designed to reduce confusion and enhance safety at intersections without traffic signals or signs. It is also outlined in the ICBC (Insurance Corporation of British Columbia) driving guidelines and is a fundamental aspect of driving judgment in everyday scenarios.
